Multimodality diagnostic imaging of diffuse esophageal leiomyomatosis.

This entity represents a rare presentation of uncommon benign smooth muscle tumors of the esophagus. The characteristic clinical, histologic, and multimodality imaging findings may distinguish this benign tumor from its malignant counterpart leiomyosarcoma and from achalasia.
