Case in brief

A woman in her 70s presented with severe abdominal pain after a fall. Imaging revealed a massive cystic lesion in the left retroperitoneum, which was confirmed to be a ruptured cyst. Surgical intervention involved laparotomy, extensive adhesiolysis, and excision of a multiloculated cyst containing about 6500 mL of fluid. Histopathology confirmed a benign serous cystadenoma.

Diagnostic / clinical pearl

Primary retroperitoneal serous cystadenomas can present with diagnostic challenges; definitive diagnosis relies on surgical excision and histopathological evaluation.
