title: Ventilation-perfusion imaging in sarcoidosis: potential for nonembolic segmental mismatch.
abstract: We report a case of a postpartum female on oral contraceptives who presented with chest pain and was initially treated for pulmonary embolism on the basis of a lobar mismatch on ventilation-perfusion imaging. Subsequent angiography revealed that the pulmonary artery was extrinsically compressed. Gallium-67-citrate imaging documented sarcoidosis with uptake in bilateral hilar nodes, both lungs and parotid and salivary glands.
