Falciform Ligament Torsion Caused by Omental Hernia Through the Foramen of Morgagni

Introduction: Torsion of the falciform ligament, one of the rarest causes of acute abdominal pain, often presents with pain in the right upper quadrant and epigastrium. Case Presentation: In this case, we present the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings of torsion of the falciform ligament that occurred in the presence of omental fat herniation through the foramen of Morgagni in an 88-year-old female patient who presented to the emergency department with acute epigastric pain. Conclusion: Torsion of the falciform ligament may develop secondary to omental hernia in the setting of Morgagni hernia and should be taken into consideration as one of the rarest causes of acute abdominal pain, even in elderly patients.
