Diffuse lung uptake on [99m]Tc-MDP bone scintigraphy-case report

ABSTRACT

A [99m]Tc-methylene diphosphate [MDP] bone scan of a 35 years old female patient performed for possible skeletal metastasis from carcinoma breast. Diffuse [99m]Tc-MDP uptake was seen in both the lung fields on [99m]Tc-MDP bone scintigraphy. Biochemical and radiological evaluation excluded all the known causes of the diffuse [99m]Tc-MDP lung uptake. Raised serum ferritin levels of 1226ng/ml [normal range for adult female = 13 - 15 ng/ml] was the only abnormal biochemical finding and attributed as the possible cause of lung uptake
