A 26-year-old male patient was referred for management of a giant splenic cyst. This was on a background of blunt abdominal trauma 10 years prior. He presented with a 6-month history of left upper quadrant abdominal pain and there was no other significant medical history. On examination, he had a palpable left upper quadrant mass. Blood tests including hydatid serology were negative. Computed tomography demonstrated a 17-cm peripherally calcified intrasplenic cyst with visceral displacement.
