title: Intracardiac malignant lymphoma detected by gallium-67 citrate and thallium-201 chloride.
abstract: An abnormal uptake of 67Ga and 201Tl in the right atrium was observed initially in a 77-yr-old man with superior vena cava syndrome. The pathological diagnosis of the surgically resected specimen was non-Hodgkin's malignant lymphoma in the right atrium. Thallium-201 is used as an imaging agent for malignant tumors. However, previous reports suggested that 201Tl scintigraphy may not be a useful method to detect cardiac involvement in patients with malignant neoplasms. In this case both 201Tl and 67Ga accumulation was observed in the intracardiac tumor by scintigraphy.
