Esophageal lymphangioma: Endoscopic ultrasound, computed tomography, and magnetic resonance imaging appearance

A case of esophageal lymphangioma in a 75-year-old man who complained of worsening dysphagia is presented. Endoscopic ultrasound showed an echogenic pattern of honeycomb or grid-like multiple microcysts within the submucosa. The sagittal image of computed tomography showed a thickened esophageal wall and fluid retention in the proximal esophageal lumen. Magnetic resonance imaging showed a high signal intensity mass with a septate-like internal structure on T2-weighted imaging and short tau inversion recovery. The tumor was completely resected by endoscopic submucosal dissection. Esophageal lymphangioma is a rare submucosal tumor that can be precisely diagnosed by CT and/or MRI.
