Thalamic bleeding: diagnosis, course and prognosis.

Isolated thalamic bleeding without involvement of the internal capsule or other neighboring structures is extremely rare. Thalamic hemorrhage often leads to bleeding into the ventricular system. The extent of the bleeding is not a valid criterion for prognosis. The chance of survival was found to be poorest in initially comatose patients. CT is eminently suitable for determining the size and position of the hemorrhage and also for the followup of thalamic bleeding. No significant correlation was found between the clinical and CT outcome.
