Spontaneous intracranial hypotension associated with cerebral venous thrombosis detected by a sudden seizure: a case report.

BACKGROUND

Spontaneous intracranial hypotension (SIH) is rare but can lead to life-threatening complications including cerebral venous thrombosis (CVT). The concurrence of CVT and SIH raises questions regarding priority.

CASE PRESENTATION: We present the case of a 52-year-old woman who developed sudden left-sided hemiparesis and generalized tonic-clonic seizures. She experienced progressive orthostatic headaches over the prior 2 weeks. Imaging showed thrombosis in the left transverse and sigmoid sinuses, bilateral subdural hematomas, and a cervicothoracic cerebrospinal fluid leak. Low molecular weight heparin was administered, but it was discontinued 2 days later due to subarachnoid hemorrhage. She was transferred to our hospital where an epidural blood patch was applied immediately, which resulted in complete symptom relief.

CONCLUSION

CVT is a rare complication of SIH that may result in devastating consequences. Treatment of SIH should be the primary focus. Prompt diagnosis and EBP application can result in a good outcome.
