Sildenafil-related cerebral venous sinus thrombosis and papilledema: a case report of a rare entity

Abstract

We present a rare case of cerebral venous sinus thrombosis associated with long-term and high-dose use of sildenafil. A 29-year-old man was referred to our neuroophthalmology clinic for bilateral visual deterioration and severe headache. He had stage 2 papilledema and other clinical and neurological examinations were normal. He had used the drug for nearly 2 years, two to three times a day. All laboratory parameters including blood count cell, coagulation panels, and genetic tests including methylene-tetrahydrofolate reductase and factor V Leiden mutation were unremarkable. The brain magnetic resonance imaging result confirmed transverse cerebral venous sinus thrombosis (CVST). The opening pressure of cerebrospinal fluid (CSF) was 43 cm H₂O with normal biochemistry and no cells. Clinicians must be aware of the possibility of CVST when the patient uses sildenafil.
