title: A huge gastric leiomyosarcoma diagnosed preoperatively through diagnostic imaging.
abstract: The authors were able to diagnose a huge gastric leiomyosarcoma prior to surgery using various diagnostic imaging techniques. The patient was a 68-year-old woman who presented with a large gas-filled mass the size of a child's head in the center of her abdomen. Based on characteristic findings from a gastric barium study, CT, MRI, and angiography, the patient was diagnosed as having a gastric leiomyosarcoma displaying extramural growth. Upon operation an extramural tumor (20 x 19 x 12 cm) originating from the gastric antrum was confirmed.
