title: Extra scrotal spermatocele causing lower abdominal pain: a first case report.
abstract: Lower quadrant abdominal pain is a common complaint evaluated in emergency departments (EDs). The number of differential diagnoses is lowered when the pain in a male patient is associated with a palpable tender mass. These diagnoses include inguinal hernia, inflamed inguinal lymph node, rectus sheath hematoma, cryptorchidism, mass derived from the spermatic cord, and polyorchidism. We report a case of extra scrotal spermatocele causing lower quadrant abdominal pain that was misdiagnosed as an inguinal hernia on several ED visits. Lower quadrant mass and pain caused by a spermatocele are unusual conditions. Upon the patient's third (ED) visit, the painful mass remained located in his right lower quadrant. The lower quadrant mass was movable on palpation and with pressure could be delivered into the superior aspect of the scrotum. The patient had an abdominal and pelvic computed tomography scan and lower quadrant ultrasound. The imaging studies revealed the mass to be a cystic structure. Surgical excision confirmed that the mass was a spermatocele. Differential diagnoses, diagnostic approaches, and treatment are discussed.
