Complicated congenital seminal vesicle cyst with unilateral renal agenesis: A rare case report

A 16-year-old male presented with persistent abdominal pain for 2 weeks. Mild elevation of liver enzymes ALT and AST was observed. Abdominal ultrasound revealed a missing right kidney and a dense cystic mass near the bladder. CT scan confirmed right kidney agenesis and identified a 7.5×7.5×10 cm cystic mass extending from the bladder to the prostate. Due to fever and worsening pain, laparoscopic surgery was performed to remove the complicated seminal vesicle cyst. Purulent ejaculate was drained and the cystic mass was completely excised. The patient recovered well and liver enzyme levels returned to normal after 1 month.
