Parametrial malakoplakia, a rare inflammatory condition, can mimic pelvic malignancy on MRI. This case highlights key imaging findings that, combined with clinical symptoms, aid in differentiating it from cancer.
Area of Science:
- Radiology
- Pathology
- Gynecology
Background:
- Parametrial malakoplakia is an uncommon chronic inflammatory condition.
- It can present with symptoms mimicking pelvic malignancy, posing diagnostic challenges.
Observation:
- A patient presented with pelvic pain and vaginal discharge, exhibiting a "frozen" pelvis on physical examination.
- MRI revealed bilateral parametrial infiltration without a discernible primary pelvic tumor.
Findings:
- The MRI findings, coupled with inflammatory symptoms, suggested an inflammatory etiology rather than malignancy.
- Resective biopsy confirmed the diagnosis of parametrial malakoplakia.
Implications:
- This case underscores the importance of considering inflammatory conditions like malakoplakia in the differential diagnosis of apparent pelvic malignancies.
- Recognizing specific MRI appearances can guide appropriate diagnostic pathways and avoid unnecessary aggressive treatments.
