Spontaneous falciform ligament necrosis: A rare case report.

Spontaneous and isolated necrosis of the falciform ligament is a rare condition. A 55-year-old lady presented with sudden onset of epigastric pain, fever and vomiting. Laboratory studies revealed less than three-fold increase in serum amylase and lipase levels. Ultrasound examination and contrast enhanced computed tomography (CECT) revealed features suggestive of inflammation and necrosis of the falciform ligament involving ligamentum teres hepatis and extending to the lesser omentum with an adjacent minimal ill-defined collection. Then, conservative management was started. However, the symptoms did not resolve completely. Therefore, CECT scan was repeated 12 days later which showed findings similar to previous scan with expansion and organization of the collection anterior to lesser omentum with peripheral enhancement, suggestive of an abscess. A minimally invasive approach to treatment was adopted. Aspiration of the collection was performed under ultrasound guidance. This was followed by continuation of supportive management. The patient improved clinically and was discharged. This case study highlights the importance of imaging in the diagnosis of falciform ligament necrosis. An innovative minimally invasive approach to treatment in the form of ultrasound guided aspiration may be considered when a collection is present adjacent to the necrosed falciform ligament.
