A Case of Seminal Vesicle Cyst Incidentally Diagnosed during Rupture of Abdominal Subcutaneous Abscess

Abstract

Seminal vesicle cyst is a rare disease and is often asymptomatic. We present a case of huge seminal vesicle cyst connected to the abdominal wall and observed as a subcutaneous abscess. An 89-year-old man presented with asymptomatic spontaneous rupture of the left lower abdominal subcutaneous abscess. Computed tomography (CT) showed a relatively low intensity cystic mass located in the Retzius' space just below the abscess, surrounding the right bladder wall laterally and connecting to the right seminal vesicle posteriorly. Biopsy of the skin around the subcutaneous abscess and aspiration biopsy of the pelvic cystic fluid showed no evidence of malignancy. We diagnosed the lesion as a seminal vesicle cyst with bacterial infection. The patient was treated with antibiotics and there has been no relapse.
