CTICasesEsophageal Leiomyoma
Imaging findings
Chest CT demonstrates a large subcarinal mass containing coarse, dystrophic calcifications immediately adjacent to and compressing the esophagus. An esophagram confirms a smooth, fixed filling defect arising from the wall of the esophagus with regular contours.
Key takeaways
Esophageal leiomyomas are benign mesenchymal tumors that typically present as intramural or submucosal esophageal masses. Unlike external cysts causing compression, leiomyomas present as fixed, intrinsic filling defects of the esophageal wall, often containing dystrophic calcifications, especially when large.
