Objective. To evaluate intestinal lesions in Burkitt lymphoma. Methods. Ultrasonography was used in the initial evaluation of 6 Japanese patients with intestinal Burkitt lymphoma. Results. Ultrasonography revealed marked wall thickening of the colon from the cecum through either the ascending or the transverse colon, which led to a target sign (4 cases) or a pseudokidney sign (2 cases). The target sign histopathologically corresponded to invagination of an occult tumor of the cecum into the ascending colon. Wall thickening of the colon when associated with a target or pseudokidney sign corresponded to marked lymph edema or a diffuse infiltration of Burkitt lymphoma cells into the intramural layers, respectively. Conclusions. Ultrasonography provides useful information in the initial evaluation of intestinal lesions with distinctive histopathologic characteristics in Burkitt lymphoma.

Key Words: intestine • Burkitt lymphoma • ultrasonography
