The falciform ligament is a peritoneal double layer that anatomically divides the right and left hepatic lobes. Abnormality of the falciform ligament is rare – less than 20 cases of torsion of the falciform ligament have been reported to date in adults. The pathophysiology of these entities is similar to intra-abdominal focal fat infarction. The clinical of the patient with torsion of the falciform ligament is abdominal pain of sudden onset and focal location. Laboratory tests can lead to diagnostic confusion with cholecystitis. Ultrasonography is usually the initial evaluation test, but the gold standard diagnosis is computed tomography. We report the case of a 30-year-old female patient reporting sudden abdominal pain that radiates to the dorsal region associated with nausea and vomiting diagnosed with torsion of the falciform ligament with ultrasonography and confirmed with computed tomography. She was treated conservatively without the need for surgical treatment, being discharged after one week hospitalization.
