title: Focal pulmonary uptake of gallium-67 due to radiation pneumonitis: the case for a misdiagnosis of Hodgkin's disease progression.
abstract: Gallium-67 scan is usually performed in patients with Hodgkin's disease and high-grade non-Hodgkin lymphoma for evaluation of disease status after treatment. We present a case of an asymptomatic woman in complete remission of Hodgkin's disease after treatment with chemotherapy and radiotherapy where a focal uptake of Gallium-67 was discovered two months after finishing treatment. As classical radiation pneumonitis can appear one to three months after finishing radiotherapy and normally has an asymptomatic course, this possibility should be considered in these cases, especially when prior chemotherapy was administered.
