FDG PET/CT in a Case of Esophageal Extranodal NK/T-Cell Lymphoma, Nasal Type.

Lymphoma involving the esophagus is rare. We describe FDG PET/CT findings in a case of extranodal NK/T-cell lymphoma, nasal type involving the larynx, hypopharynx, and cervical and upper thoracic esophagus. The esophageal tumor showed segmentally increased FDG uptake mimicking esophagitis. This case indicates that esophageal lymphoma should be included in the differential diagnosis of the hypermetabolic esophageal diseases.
