A case report of sinus hypoplasia

Abstract

Transverse sinus (TS) hypoplasia has serious potential effects on cerebral hemodynamics. Right sinus hypoplasia is less common. In this article, we present a rare case of right transverse and sigmoid sinus hypoplasia with headache complaint. A 37-year-old male patient was admitted to the emergency department because of headache and anxiety complaints continuing for the last two days. Neurological examination including fundoscopy was normal. Cranial and diffusion magnetic resonance (MR) imagining, and MR venography were planned to exclude venous sinus thrombosis. According to MR venography, right TS, right sigmoid sinus and jugular bulb were reported as hypoplasic. Patients who apply to the emergency department with headache, anxiety, and nervousness should be considered for transverse and sigmoid sinus hypoplasia.
