Abstract

Malignant lymphomas with cental and/or peripheral low densities suggesting internal infarcted necrosis arerare, probably due to the same reason as that of normal lymph nodes in which spontaneous infarction seldom occuresbecause of dual vascular connection and low oxygen consumption of activated lymphocytes. We report eight cases ofhistologically proven non-Hodgkin's lymphoma, that showed necrotic low density within tumor mass in CT scan, priorto any teatment. The locations of necrotic lymphomas were mediastinum in 3 cases, abdomen in 4 cases, and neck in1 case. The histologic types of the cases wre diffuse histiocytic (Rappaport) in 4 cases, porly differentiatedlymphocytic types in 2 cases, lymphoblastic type in 1 case, and mixed type(predominantly poorly differentiatedlymphocytic) in 1 case. It seems that malignant lymphoma can be included in differential diagnosis oflymphadenopathy with cental and/or peripheral necrotic low densities on CT.
