Unusual extraosseous tumoral accumulation of 99mTc-MDP in non-Hodgkin's lymphoma in two cases

Abstract

The authors describe a rare pattern of soft tissue uptake observed in a ^99mTc-MDP bone scintigraphy of two patients with the diagnosis of non-Hodgkin's lymphoma. Both patients had abdominal masses and bone scintigraphy revealed unusual ^99mTc-MDP uptake in the abdominal region. The possible mechanisms of soft tissue uptake of bone seeking agents are discussed.
