Sonographic and CT appearance of exogastric leiomyoma

Conventional barium examinations and endoscopy are often inconclusive in patients with subserosal, exogastric leiomyoma. Ultrasonography and CT in a patient with a large exogastric leiomyoma revealed a rounded, well-encapsulated tumour with a necrotic cavity centrally. The origin of the tumour from the stomach was demonstrated on both ultrasonography and CT.
