Falciform ligament cyst—a rare cause of abdominal pain

Falciform ligament is a fatty fibrous peritoneal fold located in the anterior abdomen. Falciform ligament cysts are rare, but they can cause significant symptoms and complications. A 38-year-old woman was diagnosed with an 8 cm falciform ligament cyst via ultrasound and computed tomography after presenting with chronic supraumbilical abdominal pain and a palpable abdominal mass. She underwent a laparoscopic resection of the cyst where the pathology subsequently confirmed the diagnosis. This article presents a literature review on the diagnosis and treatment of this rare pathological entity.
