Abstract
Primary splenic epidermoid cysts are extremely rare and typically discovered incidentally. The symptoms are variable, from an asymptomatic abdominal mass to severe abdominal pain. It is difficult to diagnose a primary splenic epidermoid cyst using imaging tests preoperatively, as it can appear similar to other cyst types. We report a 23-year-old woman who presented with left-sided abdominal pain. An advanced computed tomography (CT) scan revealed an 18 × 15 × 12 cm complicated splenic cyst, which was ultimately treated with a laparoscopic splenectomy, and the patient achieved a full recovery.
