Cortical venous thrombosis (CVT) is a common and frequently unrecognized type of stroke that affects approximately five people per million annually and accounts for 0.5-1% of all strokes. Exact incidence in India is yet to be documented. Puerperal CVT may account for the majority of CVT cases in India. Cerebral venous sinus thrombosis (CVST) usually affects young to middle aged groups. Outcome of CVST patients may vary from complete recovery to permanent neurological deficits, with varying presentation of the natural course of the disease. Factors related to poor outcome were papilledema, altered consciousness, coma, age older than 33 years, diagnostic delay >10 days, intracerebral hemorrhage, and involvement of the straight sinus. This case report is of thrombosis in the deep venous system of brain causing venous infarction of unilateral thalamus. There are very few cases reported all over the world with unilateral thalamic venous infarct. Prognosis of unilateral deep cerebral vein thrombosis is said to be better than that of bilateral thrombosis, if detected early and timely treated. Patient with a unilateral thrombosis may show complete recovery from his neurologic symptoms. Reports of reversible edema of the thalamus are well documented. In this case, patient is overall well preserved except that he continues to have recent memory impairment even after 4 weeks of discharge from hospital.
