Lateral Sinus Thrombosis

Infectious or noninfectious thrombosis of the lateral sinus of the brain. Septic thrombosis may be associated with OTITIS MEDIA or MASTOIDITIS. $CRANIOCEREBRAL TRAUMA$; BRAIN NEOPLASMS; NEUROSURGICAL PROCEDURES; THROMBOPHILIA; and other conditions may result in non-septic thrombosis. Clinical manifestations include headache, vertigo, and increased intracranial pressure. Extension of the thrombus into adjacent venous structures may result in INTRACRANIAL HEMORRHAGES or SEIZURES.
