Summary
A case of esophageal leiomyosarcoma, for which CT scan, endoscopie ultrasonography (EUS) and angiography were employed for preoperative diagnosis is reported. CT scan identified an exophytic mass which had no rim-enhancement in the lower end of the esophagus. EUS revealed a homogeneous mass originating from the muscularis propria. Angiography showed a mildly hypervascular tumor. Histologically, the resected specimen was a leiomyosarcoma. These results suggest that the evaluation by EUS combined with CT scan and angiography is useful in differentiating smooth muscle tumors from other submucosal tumors.
