title: Cystic Lymhangioma of the Lesser Sac in Adult Presenting with Features of Gastric Outlet Obstruction - A Case Report.
abstract: Cystic lymphangioma is a paediatric benign tumour, occurs commonly in head and neck region. Adult intraabdominal lymphangiomas are uncommon and only few cases of lesser sac cystic lymphangioma are reported in the literature. We present a case of lesser sac cystic lymphangioma in a 26-year-old lady who presented with features of gastric outlet obstruction. Clinical examination revealed a 10x10 cm firm, non tender, mobile intraabdominal lump in the epigastrium. An upper gastrointestinal endoscopy showed possible external compression at the body of the stomach. Ultrasound demonstrated a multicystic lesion, with internal echoes in one locule. CECT showed a large multiloculated cystic lesion with hyper-dense content in the lesser sac extending up to the left lobe of the liver and indenting the stomach, lesser sac, and upper border of pancreas. On surgical exploration, a 10X8 cm multi cystic lesion with clear fluid was found in the lesser sac very close to the lesser curvature of stomach. Histopathological examination of the excised lesion showed features of cystic lymphangioma. Though very rare, intraabdominal cystic lymphangiomas should be considered in all atypical cases of gastric outlet obstruction. A reasonable knowledge about these benign lesions will aid in establishing the diagnosis and surgical management.
