Foreign body pulmonary embolism originating from a gunshot wound to the head.

Foreign body pulmonary emboli from a cranial venous sinus are unusual. Two patients are presented with gunshot wounds to the head who subsequently developed foreign body pulmonary emboli. Neither had any pulmonary complaints at presentation or during followup. Radiologists and primary care physicians should be aware of the possibility of distal missile pulmonary emboli when a foreign body enters the peripheral venous system or an intracranial venous sinus.
