title: [A case of huge duodenal leiomyosarcoma].
abstract: A case of duodenal leiomyosarcoma with large central necrosis was reported. Tumor was 15 X 10 X 10 cm in size. Ultrasonography showed a cystic tumor with thick wall in the right upper abdomen. CT scan revealed a gas formation in the central cystic cavity of the tumor. The gas formation was probably caused by bacterial infection. The diagnosis was confirmed histologically.
