Rare case of retropubic parasymphyseal cyst in a male patient

Introduction Retropubic parasymphyseal cysta are rare, and few cases have been reported in men. Case presentation A 65‐year‐old male patient presented with a 6‐month history of pelvic and perineal pain. Magnetic resonance imaging revealed a high‐intensity, irregular‐shaped mass extending from the pubic symphysis to the bladder. Contrast enhancement revealed no uptake in the central part of the mass, indicating a cystic component. Computed tomography showed erosion of the pubic symphysis and pubic osteophytes. Pathological findings of biopsy specimens revealed inflammatory fibrous tissue but no malignancy. The definitive diagnosis was retropubic parasymphyseal cyst associated with inflammation. The patient was treated with cefazolin from 1 day before surgery until postsurgical day 7. Oral antibiotic therapy was then prescribed for 1 month to maximize treatment. After 2 months, the patient’s symptoms resolved. Conclusion Retropubic parasymphyseal cysts with inflammation and smaller asymptomatic cysts can be managed effectively with conservative or minimally invasive treatment.
