Case:
A 17-year-old male who presented with urinary retention was found to have an alveolar rhabdomyosarcoma involving the peritoneum, prostate, and bladder. After neoadjuvant chemotherapy, a residual mass in the obturator internus muscle was resected through a perineal approach and inferior pubic ramus osteotomy.
Conclusion:
Tumors in the obturator internus are uncommon, resulting in limited literature on approaches and technical considerations for resecting masses in this region. We present a case of successful tumor resection from the obturator internus muscle using this approach while preserving neurovascular and urogenital function with no recurrence at 24-month follow-up.
