- Abstract: Lipiodol brain embolism is a rare complication associated with transcatheter arterial cheomoembolization (TACE). The present case describes a patient with lipiodol brain embolism who presented with several symptoms, including drowsy mental state, right facial palsy, and weakness in the right upper and lower limbs. The patient's non-enhanced computed tomography scan and magnetic resonance imaging (MRI) findings revealed multifocal lipiodol deposition and an acute infarction of the brain. A retrospective review of the angiography findings revealed a right inferior phrenic artery-pulmonary vein shunt, which was not observed during the previous TACE. Three days after TACE, the patient's symptoms improved; however, the extent of the brain hyperintensity had widened further on the following MRI. The patient gradually recovered and was finally discharged.
