Report summary

MRI of the pelvis in a woman with known treated cervical cancer shows an enhancing lesion in the upper vagina/vaginal vault at the cervix region that extends to the posterior urethral wall, suspicious for residual or recurrent tumour. There is also right paravaginal soft-tissue thickening (mix of post-treatment change and possible residual/recurrent tumour) and mild-to-moderate free fluid in the pelvis.

Findings

Upper vagina / vaginal vault (cervix region)

moderate confidence

Needs attention

Approximately 20 × 23 × 23 mm altered-signal-intensity lesion involving the upper vagina/vaginal vault, showing post-contrast enhancement and partial diffusion restriction, raising concern for residual/recurrent viable tumour.

In plain words: A roughly 2 cm abnormal area at the top of the vagina takes up contrast dye in a way that suggests active tumour tissue may still be present or have come back. 'Diffusion restriction' is an MRI signal often seen with tumour.

Vagina and paravaginal tissues

moderate confidence

Needs attention

Right anterolateral paravaginal soft-tissue thickening with surrounding oedematous signal changes, likely representing a combination of post-treatment inflammatory/fibrotic changes and residual/recurrent tumour.

In plain words: The tissue beside the vagina on the right is thickened and swollen. This may be a mix of scarring/inflammation from prior treatment and possible remaining or returning tumour.

Urinary bladder and urethra

moderate confidence

Needs attention

Abnormal soft tissue extends to/adheres with the posterior aspect of the urethra. No definite intraluminal urinary bladder mass identified on the provided images.

In plain words: Abnormal tissue touches the back of the urethra. No clear mass was seen inside the bladder itself.

Peritoneal cavity

high confidence

Needs attention

Mild to moderate free fluid is noted within the pelvis.

In plain words: There is a small to moderate amount of free fluid in the pelvis.

Uterus

high confidence

Normal

Uterus is atrophic.

In plain words: The womb is small and shrunken, which is a normal change after menopause and treatment.

Adnexa

high confidence · not localized

Normal

Both adnexa appear unremarkable for age. No adnexal mass lesion identified.

In plain words: The areas around the ovaries look normal for her age, with no mass seen.

Lymph nodes

high confidence · not localized

Normal

No significant/bulky pelvic or inguinal lymphadenopathy identified.

In plain words: No enlarged lymph nodes were seen in the pelvis or groin.

Bones (pelvis)

high confidence · not localized

Normal

No obvious focal suspicious osseous lesion identified within the visualized pelvic bones.

In plain words: No suspicious areas were seen in the pelvic bones shown on the scan.

Cervix

high confidence

Cervix is poorly delineated and appears flushed with/indistinguishable from the adjacent vaginal vault, in keeping with the known treated disease and post-treatment changes.

In plain words: The cervix cannot be clearly separated from the top of the vagina, which is expected after the cancer treatment she has already had.

Vagina / urethra

moderate confidence

The lesion extends inferiorly/anteriorly towards the posterior wall of the urethra, with associated abnormal soft tissue along the right anterolateral paravaginal region and apparent adherence/involvement of the posterior urethral wall.

In plain words: The abnormal area reaches toward and appears to attach to the back wall of the urethra (the tube that drains urine) and involves tissue beside the vagina on the right.

Findings

Left hip region (patient's left femoral head/neck)

moderate confidence

Needs attention

The left femoral head and acetabular region show a small focus of altered marrow signal and slightly irregular joint contour compared with the smoothly rounded, uniformly fatty right femoral head at the same level.

No abnormality seen

moderate confidence · not localized

Normal

On these masked ADC slices, aside from the structures described above much of the pelvic tissue is thresholded to black or shown only as scattered bright speckle, so no additional discrete deviating structure was traced. The central and paired lateral structures listed above are the only coherent tissue regions examined here.

Central pelvic soft-tissue mass

high confidence

A large, ill-defined mass occupies the midline central pelvis on the more cranial slices, with strikingly heterogeneous signal: broad areas of very high STIR signal mixed with intermediate-signal solid tissue and several sharply rounded, uniformly bright fluid-filled locules. It has no clear fat plane from the surrounding structures and expands to fill the space between the pelvic side walls. This is the most significant finding of the series because it is a space-occupying process that distorts and displaces the adjacent central pelvic structures, outranking the well-defined bony and vascular structures which retain their normal outline.

Presacral / lower midline soft tissue

moderate confidence

Immediately inferior to the central structure, a vertical dark cleft descends toward the perineum, flanked symmetrically by intermediate-signal soft tissue; it is thinner and more uniform than the cavity above it.

Paired lateral pelvic structures

moderate confidence

Symmetric rounded regions of darker (low-ADC) grey sit on each side of the pelvis, on the patient's right (image left, cx~0.15) and left (image right, cx~0.85), most evident on slices 11-14. They are lower in ADC value than the central structure and lie lateral to it, without a discrete margin distortion visible on these slices.

Signal-void foci within the mass

moderate confidence

Several sharply marginated, very dark round foci lie within the central mass, some rimmed by enhancing tissue; these are pockets of no signal (gas or blooming) sitting inside the enhancing soft tissue and distinguishing it from the surrounding vascularised tissue.

Bilateral iliac fossa foci

moderate confidence

On the caudal slices there are rounded and irregular high-STIR-signal foci within the soft tissue of both iliac fossae, adjacent to the iliac bones, standing out against the darker surrounding muscle; they are present on both the right and left.

Right gluteal/iliac soft tissue

low confidence

Patchy strands of increased enhancement course through the fat-suppressed soft tissue lateral to the right iliac bone, appearing as bright linear signal against the darker suppressed background.

Urinary bladder

moderate confidence

On the superior slices the bladder is a smooth-walled, thin-rimmed structure containing homogeneous high T2 signal fluid in the anterior midline; its posterior wall abuts the central intermediate-signal mass, with loss of the intervening fat plane at that interface.

Subcutaneous fat and superficial soft tissues

moderate confidence

Fine bright reticular streaks are present within the subcutaneous fat of both thighs and the lower pelvis, more prominent than the underlying muscle signal.

Mid-lower rounded structure

moderate confidence

A rounded, well-defined structure with a bright thin rim and a lower-signal center sits in the mid-lower soft tissues below the upper mass; its margin is smooth and it does not distort the surrounding tissue. It is more sharply circumscribed and less signal-heterogeneous than the upper mass.

Vascular flow voids

moderate confidence

Paired small round dark structures with bright rims flank the midline on multiple slices, consistent with the appearance of pelvic vessels in cross-section; they are draped along the margins of the central mass.

Fluid-filled structure, inferior midline

moderate confidence

In the more posterior slices a smoothly walled, low-signal ovoid structure sits in the inferior midline beneath the mass, with a thin enhancing rim; the mass lies immediately superior to and contacts its upper margin.

Lower lumbar / sacral vertebrae

moderate confidence

The posteriorly located vertebral bodies and their intervening discs are seen in profile; the anterior sacral margin lies immediately behind the mass with the intervening fat effaced.

Peripheral soft tissues

low confidence

The lateral and posterior soft tissues appear as fragmented intermediate-to-low ADC speckled material bilaterally, symmetric in distribution, with the outer pelvic contour thresholded to black on this map.

Rectum / posterior pelvis

low confidence

The rectum lies posterior to the central mass in the caudal slices, appearing as a rounded structure with mixed intraluminal signal; its anterior wall is closely apposed to the mass with reduced intervening fat.

MRI

Whole-exam read: 10 of 11 series, 334 representative slices in total.

Findings

1.In the middle of the pelvis there is a large, ill-defined area with a mix of appearances — broad zones that look like fluid, some solid-looking tissue, and several sharply rounded fluid pockets — with no clear line of fat separating it from nearby structures. Importantly, the automated readings disagreed about this area: they did not reach the same conclusion, so a human radiologist is needed to decide what it actually is. We are not picking a side here.
2.Just below that central area, one reading described a vertical dark line running down toward the area between the legs, with soft tissue on either side of it. Other readings did not mention this, so it is not settled.
3.On each side of the pelvis, rounded areas were seen that appear darker on a map that reflects how water moves in tissue. One of the other readings also noted these, but it is not confirmed.
4.On one of the specialized maps, apart from the areas already described, no additional separate abnormal structure could be traced. The readings disagreed about this point as well, so a radiologist should settle it.
5.Within the central area there are several very dark, sharply outlined round spots — pockets that give off no signal, which can represent gas or a scanning effect. Only one reading described these, so they are not settled.
6.Near the pelvic bones there are rounded, bright spots in the soft tissue standing out against the darker muscle. The scan could not confirm which side of the body these are on, so no side is being stated, and this was noted by only one reading.
7.One reading described a small area of altered signal in the bone marrow of one hip and a slightly uneven joint outline compared with the other side. The other readings did not mention this, so it is something a single reading raised rather than an established finding.
8.Patchy bright streaks were seen running through the soft tissue beside one of the pelvic bones after contrast. The scan could not confirm which side this is on, and the readings disagreed about it, so it needs a radiologist to sort out.
9.The bladder appears as a smooth, thin-walled structure holding fluid at the front of the pelvis. Its back wall lies right up against the central pelvic area, with the normal thin layer of fat between them not visible at that point. All of the readings agreed on this.
10.One reading noted fine bright web-like streaks in the fatty layer just under the skin of both thighs and the lower pelvis. The other readings did not mention this.
11.A separate, well-defined rounded structure with a thin bright rim and a darker center sits lower down, beneath the central area, with smooth edges that do not push on nearby tissue. This was noted by one reading and is not settled.
12.Small paired dark round structures with bright rims sit alongside the midline; these have the typical look of blood vessels seen in cross-section. Some readings noted this and some did not.
13.A smooth-walled, fluid-containing oval structure with a thin rim that takes up contrast sits low in the midline, beneath and touching the central area. This was noted by some readings and is not settled.
14.The lower spine (lumbar and sacral bones) and the discs between them are seen from the side. The front edge of the sacrum lies just behind the central area, with the normal fat between them not visible. This was noted by some readings and is not settled.
15.The soft tissues around the edges of the pelvis appear as speckled, symmetric material on one of the maps. This was noted by some readings and is not settled.
16.The rectum lies behind the central area, and its front wall sits closely against it with less fat than usual between them. This was noted by some readings and is not settled.

Impression

This was an MRI (a scan using a magnetic field and radio waves, not X-rays) of your pelvis, including images taken after a contrast dye was given to make certain tissues stand out. The reading centered on a large area in the middle of your pelvis, and the automated readings did not agree about what it is — that disagreement is important and needs a human radiologist to settle it. Several smaller observations were also noted, most of which were mentioned by only one reading and are not settled. Given the reason for your scan, it would be sensible to review these results with your doctor promptly.

The central finding of this study is an area in the middle of the pelvis that the automated readings could not agree about — which is exactly why a trained radiologist and your treating doctor need to review the actual images rather than rely on these summaries. Several observations describe this area touching or lying right against nearby structures (such as the bladder, the rectum, and the front of the sacrum) with the normal thin fat layer between them not visible; loss of that fat plane can happen for different reasons and, by itself, does not tell you the cause. Many of the other items were raised by only one reading, or the readings disagreed, so they should be treated as things to check rather than confirmed facts. Because these results are being read in the context of a follow-up after cancer treatment, it is important not to draw conclusions from this explanation alone — the meaning depends on comparison with your earlier scans and on your doctor's overall assessment.

Questions for your doctor

1.The automated readings disagreed about the large central pelvic area — what does a radiologist conclude it actually is when the images are reviewed carefully?
2.How does this area compare with my scans from before and during treatment?
3.The reading noted that the normal fat layer between this area and my bladder, rectum, and sacrum was not visible — what does that mean in my situation, and does anything further need to be checked?
4.Some items (the hip marrow signal, the streaks near a pelvic bone, and the skin-layer streaks) were raised by only one reading or the side could not be confirmed — do any of these need additional imaging or a repeat scan to clarify?
5.Are any additional tests, a biopsy, or a follow-up scan recommended based on these findings?
6.How soon should I be seen, and are there any symptoms I should watch for in the meantime?

Glossary

MRI:: A scan that uses a strong magnet and radio waves (no X-rays) to make detailed pictures of the inside of the body.
Contrast (dye):: A liquid given during the scan that highlights certain tissues and blood vessels so they show up more clearly.
Enhancement:: Tissue appearing brighter after contrast dye is given, which shows how the dye is taken up in that area.
STIR / fat-suppressed images:: MRI settings that dim the signal from fat so that fluid and other tissues stand out more clearly.
Diffusion / ADC map:: A special MRI technique and its map that reflect how easily water moves within tissue; it is used to compare different areas.
Signal void:: A spot that gives off no signal and appears very dark; it can represent gas or a scanning effect.
Fat plane:: A thin layer of fat that normally separates neighboring structures; when it is not visible, two structures appear to be touching directly.
Effaced:: Flattened or no longer visible, often used when a normal separating layer can no longer be seen.
Flow void:: The dark appearance blood vessels normally have on MRI because blood is moving through them.
Locule / cystic focus:: A small rounded pocket that contains fluid.
