Cerebral venous sinus thrombosis associated with spontaneous intermittent cerebrospinal fluid rhinorrhea: a case report

To present a rare case of cerebral venous sinus thrombosis [CVST]. A 43-year-old woman presented with coma and was diagnosed as a case of CVST. She recovered in a few days with heparin treatment. Many possible risk factors for CSVT were negative in the patient but intermittent cerebrospinal fluid [CSF] rhinorrhea was accidentally noticed. Cerebral computed tomography and magnetic resonance imaging were done. The patient was diagnosed as having spontaneous intermittent CSF rhinorrhea due to a defect in the base of the skull. This case showed the importance of being aware that a defect in the base of the skull may lead to intermittent CSF rhinorrhea in patients with CVST
