Medtronic received information from literature that a patient was suspected to have foreign body emboli after pipeline implantation.The patient underwent uneventful coil-supported pipeline embolization of a right paraophthalmic aneurysm.It was reported that the patient was tired during the next 2 months.On week 8 post-embolization, she developed sudden headache and neck pain while watching a foreign movie and noticed difficulty reading the subtitles.Neurologic examination revealed left inferior homonymous quadrantanopsia.Ct and mr imaging demonstrated a 2 to 3 cm right parieto-occipital hematoma, with multiple subcortical enhancing lesions scattered throughout the ipsilateral hemisphere.The clopidogrel dosage was titrated to an empiric range of 100¿200 p2y12 reaction units (pru).After an 8-week course of dexamethasone, mr imaging showed near-complete resolution of perilesional edema and decreased lesion enhancement, with no new lesions.
