Abstract

Cerebral lipiodol embolization is a rare but known complication of lymphatic embolization for plastic bronchitis. The classic imaging finding on a noncontrast head computed tomography is multiple small areas of hyperdensity within the cerebral hemispheres, which represent lipiodol deposition in the brain. We report a case of lipiodol deposition in the middle cerebral artery following lymphatic embolization, producing an "ultradense" vessel sign on noncontrast computed tomography.

Keywords: Cerebral lipiodol embolization; Lymphatic embolization; Plastic bronchitis; Ultradense vessel.
