The esophagus is the least commonly involved gastrointestinal organ, accounting for fewer than 1% of patients with lymphoma. Such involvement is mostly secondary, from mediastinal lymph nodes or gastric lymphoma. The primary form arises from the esophageal wall itself and occurs much less frequently. Primary esophageal lymphoma is mostly seen in male patients with Hodgkin's disease. A primary non-Hodgkin's lymphoma of the esophagus with concomitant involvement of the bone marrow is presented, and imaging features of esophageal lymphoma are reviewed.
