Association of Cerebral Venous Thrombosis and Intracranial Hypotension: Review of 3 Cases.
Cerebral venous thrombosis is a rare complication of intracranial hypotension. We describe 3 cases in which this phenomenon occurred, as a result of a lumbar puncture or due to a spontaneous cerebrospinal fluid leak. We emphasize the importance of early detection of the intracranial hypotension syndrome, the most common clinical manifestation being orthostatic headache. It is not an innocent condition as it is associated with other potential complications such as subdural hygroma/hematoma, cranial nerve palsies, cerebellar tonsillar descent, and even brainstem manifestations. Any change in the typical features of the syndrome should lead to further investigation. Repeat cerebral imaging is important in that situation, including ruling out cerebral venous thrombosis.
