High grade Burkitt lymphoma in an immunocompetent young patient: Concomitant gastric and ileal localizations.

Burkitt lymphoma is a highly aggressive and rapidly growing B cell non-Hodgkin lymphoma with heterogeneous pattern of manifestations. We present a rare case of a 39-year-old immunocompetent male with double localization of Burkitt lymphoma: gastroduodenal and ileal tract. The gastric location is extremely rare, and the association with another site is unusual with only few reports in the literature. Imaging modalities play a crucial role in correct diagnosis as it can manifest as a focal mass or as segmental wall thickening. Radiologists should recognize common and uncommon presentations and sites of Burkitt lymphoma given the urgency of potential treatment, in order to improve the patient's prognosis.
