Focal necrosis of the falciform ligament as a rare cause of abdominal pain: A case report.

Abstract

The falciform ligament, a peritoneal fold that anatomically separates the right and left lobes of the liver, may infrequently be a cause of patients' complaints. In very rare instances, fatty appendages of the falciform ligament may undergo torsion, resulting in fat infarction. Despite its rarity, falciform ligament pathologies often mimic common abdominal issues, leading to misdiagnosis. Herein, we report a case of inflammation and necrosis of the falciform ligament in a 72-year-old female. The patient presented with abdominal pain, a positive Murphy's sign, and elevated inflammatory markers. Imaging, including a computed tomography (CT) scan, was pivotal in confirming the diagnosis of falciform ligament necrosis. Contrary to the proposed surgical approach (resection of the falciform ligament) in some reported cases, conservative management (including analgesia, hydration, and antibiotics) proved successful in this case. This report emphasizes the importance of considering falciform ligament torsion in upper abdominal pain differential diagnoses and highlights the key role of imaging for accurate diagnosis.
