Background
Cerebral venous sinus thrombosis (CVST) is an uncommon type of stroke. Subarachnoid hemorrhage (SAH) is becoming more widely recognized as a possible complication of CVST, and this concomitant scenario frequently complicates diagnosis and prognosis.
Case presentation:
In this study, we report a rare case of CVST in a 76-year-old woman who presented with an isolated headache. The patient was diagnosed with subarachnoid hemorrhage complicated by CVST by computed tomography venography (CTV) and magnetic resonance venography (MRV). Low molecular weight heparin (Fraxiparine, 4100 IU, subcutaneous injection, once every 12 hours) was administered for anticoagulation. The patient developed no recurrence of thrombosis during the 6-month follow-up period. The literature on similar cases was also reviewed.
Conclusions
Clinicians should be aware of the possibility of CVST when patients are treated for subarachnoid hemorrhage.
