CASE REPORT: PRIMARY RETROPERITONEAL VENOUS HEMANGIOMA MIMICKING RETROPERITONEAL LYMPHADENOPATHY IN PHRACHOMKLAO HOSPITAL
Abstract
A 35 year-old male patient presented with abdominal pain. Ultrasound (u/s) and computed tomography (CT) suspected to be caused by distal CBD stone obstruction and additional incidental findings ofa large retroperitoneal hypodense nodule at para aortic region, appearing to engulf the left renal vein, suggestive of lymphadenopathy. A diagnosis of paraaortic lymphadenopathy was made based on U/S and three studies of CT findings to be hypodense, non-enhancing lesion of the mass which was atypical for hemangioma. However; upon laparoscope resection, histopathologically examination revealed retroperitoneal soft tissue mass to be a venous hemangioma. Retroperitoneal venous hemangioma is a very rare condition, which accurate preoperative diagnosis is very difficult.
