Transverse Sinus Thrombosis Secondary to Internal Jugular Vein Abnormalities.

Cerebral sinus venous thrombosis (CSVT) is a rare disorder that presents with highly variable neurological manifestations ranging from headache, confusion, seizures, coma to stroke-like symptoms. It predominantly affects young adults and children, with female predilection. We are presenting a case of 59-year-old female with left-sided transverse and sigmoid sinus thrombosis most likely secondary to dehydration on top of chronically diminutive left transverse sinus and internal jugular vein.
