CONCOMITANT GASTRIC AND LUNG UPTAKE OF TC-99M MDP ON BONE SCAN IN A PATIENT WITH DIFFUSE LARGE B-CELL NON-HODGKIN’S LYMPHOMA

Abstract

Extra osseous uptake of Tc-99m Methylene Di Phosphonate (MDP) is not an uncommon finding on skeletal scintigraphy. However, concomitant lung and gastric uptake is a rare presentation. We presented a case report of a young male whose bone scan revealed lung and stomach uptake with a cold lesion over T7 vertebra. CT guided biopsy revealed diffuse large B-cell Non-Hodgkin’s lymphoma. Lung and gastric uptake of Tc-99m MDP on bone scan guides the reporting physician about the soft tissue calcinosis due to hypercalcemia associated with either malignant or non-malignant conditions.
