Laparoscopic management of cystic lesion of the hepatoduodenal ligament

Cystic neoplasms of the hepatoduodenal ligament are exceedingly rare lesions that pose significant diagnostic and therapeutic challenges due to their nonspecific clinical presentation and complex anatomical location. These lesions, which include cystic lymphangiomas, hydatid cysts and benign cystic neoplasms, often mimic other cystic abdominal masses, complicating preoperative diagnosis. We present a case of a 29-year-old male with a cystic lymphangioma located in the hepatoduodenal ligament, highlighting the role of advanced imaging and laparoscopic excision in effective management. This report underscores the importance of high clinical suspicion, comprehensive imaging and meticulous surgical technique in addressing these uncommon cystic neoplasms.
