BackgroundElevation of bone for the treatment of depressed skull fractures overlying venous sinuses is rarely required or performed. The neurosurgical literature only describes a handful of cases of surgical intervention in which the posterior two-thirds of the superior sagittal sinus was involved. Clinical course is variable, signs and symptoms suggest increased intracranial pressure, and all conservative measures should be exhausted before proceeding with the surgical route.Case DescriptionA 27-year-old man presented with a self-inflicted gunshot wound to posterior head. On presentation, there were no neurologic complaints. On imaging, the bullet fragment was associated with a comminuted anteriorly displaced fracture over the torcula. Vessel imaging showed tapering of the superior sagittal sinus and transverse sinuses near the torcula, suggesting narrowing due to mass effect. The patient did not respond to initial conservative management and developed worsening diplopia and papilledema concerning for increased intracranial pressure. Occipital/suboccipital craniectomy was performed with elevation of depressed skull fracture, decompression of dural venous sinus, removal of bullet, and mesh cranioplasty. Repeat ophthalmology examination postoperatively showed improvement in optic disc edema and diplopia.ConslusionsThis case confirms that the approach of surgical management of superior sagittal venous sinus injuries associated with skull fractures described in the literature also can be used successfully for injuries over the torcula if conservative management does not help alleviate the symptoms and results in good outcome. It was felt that delayed surgery also plays an important role, as it gives time for scar tissue to form, which may help to protect the sinus from injury during surgery.Copyright © 2020 Elsevier Inc.
