Necrosis of the ligamentum teres hepatis is a very rare and misdiagnosed pathology. Four cases have been reported in the literature. Clinical symptoms with acute abdominal pain suggest peritonitis. The diagnostic may be obtained by CT scan of the abdomen revealing a hypo/dense circular lesion, anterior to the liver, to the junction of the segments III and IV, associated with inflammation. The mechanism of isolated necrosis of the round liver ligament remains unclear. In the absence of a preoperative diagnosis, a video-laparoscopic exploration is proposed.
