Spontaneous Intracranial Hypotension Complicated by Cortical Vein Thrombosis

ABSTRACT

Spontaneous intracranial hypotension (SIH) is characterized by orthostatic headache, diffuse dural thickening, and enhancement in MRI associated with low cerebrospinal fluid pressure. While SIH causes several complications such as subdural hematoma, cranial nerve palsies, and altered consciousness, cerebral venous thrombosis caused by SIH has been rarely described. We report a patient presenting with generalized tonic-clonic seizure that was probably caused by cortical vein thrombosis that had developed after SIH.
