Persistent intracranial hypertension caused by superior sagittal sinus stenosis following depressed skull fracture. Case report and review of the literature.

Intracranial hypertension caused by a compound depressed skull fracture on the posterior part of the superior sagittal sinus is a rare condition, and nonspecific symptoms and signs can delay appropriate diagnosis and treatment. The authors report on a case of intracranial hypertension that persisted despite conservative treatment, including anticoagulation therapy, which did not improve severe flow disturbance related to the venous sinus compression. Management of this rare condition is discussed and the literature is reviewed.
