Transverse (Lateral) Sinus Thrombosis
Synonyms
Definition
The intracranial lateral (transverse) venous sinuses (right and left) drain venous blood from the confluence of sinuses to the sigmoid sinuses. Thrombosis of the transverse (lateral) sinus can lead to reduced drainage of venous blood and secondary reduction in absorption of cerebrospinal fluid. As a result, transverse sinus thrombosis can lead to increased intracranial pressure (ICP), venous hypertension, or secondary hydrocephalus.
Symptoms of transverse sinus thrombosis can develop acutely and may mimic idiopathic intracranial hypertension (IIH). Typical symptoms of increased ICP include headache, diplopia associated with cranial nerve (CN) VI palsy, papilledema, nausea, and vomiting. Furthermore, patients might also exhibit CN VII or CN VIII dysfunction.
