title: Positive gallium-67 scintigraphy associated with pulmonary embolism.
abstract: A 54-year-old man presenting with symptoms and signs of pulmonary embolism demonstrated gallium-67 accumulation within the right lower lung field in the region of a pulmonary embolism with effusion. An associated infectious process was ruled out. This is contrary to the usual clinical experience and identifies a potential pitfall in the use of gallium-67 as an aid in the differential diagnosis of pulmonary embolism and pneumonitis.
