[Cystic abdominal lymphangioma in adults].

Cystic abdominal lymphangioma is a rare tumor in adult age. It occurs usually in children and is localised mostly in the head and neck. Only 2-8 % of lymphangiomas are localised intraabdominally. We present a case of a 20-year-old man who complained about acute abdominal pain after physical activity. Diagnosis of intraabdominal multilocular cyst was done by ultrasound, computed tomography and coeliacography. The definitive diagnosis of lymphangioma of the hepatoduodenal ligament was established by laparotomy and histologic examination of the specimen. Cystic abdominal lymphangioma is a rare disease in adults with difficult preoperative diagnosis. The surgical extirpation often completed with resection of involved organ is the method of choice in the treatment of this rare disease.
