Retrorectal tumours: a case report

The authors describe a case of retrorectal tumour in a 48-year-old female. Retrorectal tumours are rare, and their diagnosis is notoriously difficult and late. In this case the first-step diagnosis was made on the basis of clinical findings and radiological investigations such as abdominal ultrasonography. The second step included pelvic CT scans and MR imaging which yielded more precise anatomical details and information for the best surgical approach. We opted for a posterior approach with complete, easy removal of the tumour mass which, after pathological examination, turned out to be an epidermoid cyst. The postoperative course was uneventful and, one year after operation, the patient complains only of mild, irregular perineal pain with completely negative radiological investigations (US and CT scan).
