Abstract:
A 30-year-old man presented with headache, left hemiparesis, and uncal herniation. Magnetic resonance imaging showed acute infarction in the right middle cerebral artery (MCA). Lifesaving craniotomy proceeded because of the uncal herniation. Assessment of brain tissue led to a diagnosis of MCA dissection. His skin biopsy showed ultrastructural abnormalities of dermal connective tissue. This is the unique case that dissection was diagnosed from both a biopsy specimen of the MCA and the dermal connective tissue.
