Hyperdense Sylvian Fissure MCA "Dot" Sign Stroke 32:84-88, Barber,P.A.,et al, 2001 See this aricle in Pubmed Article Abstract The hyperdense appearance of the main middle cerebral artery (HMCA) is now a familiar early warning of large cerebral infarction, brain edema, and poor prognosis. This article describes the hyperdensity associated with embolic occlusion of branches of the middle cerebral artery in the sylvian fissure (MCA "dot" sign). We define it and determine its incidence, diagnostic value, and reliability. The MCA dot sign is an early marker of thromboembolic occlusion of the distal MCA branches seen in the sylvian fissure and is associated with better outcome than the HMCA sign.
