Intracranial hypertension caused by superior sagittal sinus stenosis secondary to a depressed skull fracture: Case report and review of the literature.

Depressed fractures that occur on the superior sagittal sinus (SSS) cause stenosis or thrombosis of the sinus in 11.5% of cases. Despite this, the appearance of signs and symptoms derived from high intracranial pressure is an infrequent event. So far, only 17 cases of venous sinus injury causing intracranial hypertension have been documented. It is necessary to establish treatment immediately before clinical suspicion. Surgical treatment by craniectomy is a fast, effective and safe alternative according to the series. However, it is necessary to anticipate the possibility of haemorrhage in the operating room. The case of a 7-year-old girl admitted for traumatic brain injury (TBI) with the diagnosis of a left parasagittal occipital sinus fracture that stenosed the posterior third of the superior sagittal sinus is presented. Upon arrival, she was asymptomatic, and conservative management was selected. Subsequently, the patient began to present with headache, nausea, vomiting and diplopia associated with bradycardia and apnoea pauses of central origin. She underwent surgery with a craniectomy with satisfactory clinical and radiological evolution and normalization of the intracranial pressure (ICP) registry.
