Abstract

Retroclival hematomas are a rare entity, presenting anteriorly to the brainstem in the epidural, subdural, or subarachnoid space. Although those that develop in the epidural space often arise from trauma, subdural retroclival hematomas frequently occur spontaneously in the setting of coagulopathy, aneurysm rupture, or pituitary apoplexy, with many cases having an unknown etiology. 1-4 Although most are treated with conservative management, surgical intervention is preferred for those presenting with evidence of brainstem compression, hydrocephalus, worsening neurological deficits, and clinical deterioration. 5 In this report, we present the case of a 75-year-old woman with a medical history of mitral regurgitation, nonischemic cardiomyopathy, and atrial fibrillation on warfarin presenting with 4 days of temporoparietal headaches and double vision. On examination, the patient demonstrated right abducens and hypoglossal nerve palsies. Computed tomography revealed a subdural hemorrhage within the retroclival cistern, extending into the dorsal inferior aspect of the C2 vertebral body, resulting in posterior displacement of the pons, medulla, and proximal cervical spinal cord. Spinal and cerebral angiograms did not show evidence of any vascular malformation. An endoscopic transclival approach was selected for hematoma evacuation. Key surgical steps included harvesting of nasoseptal flap, endoscopic transnasal approach to the sellar/subsellar space, transclival drilling, retroclival hematoma evacuation, and clival reconstruction. The patient tolerated the procedure well and was discharged 15 days postoperatively with resolution of prior cranial nerve deficits. Postoperative computed tomography imaging revealed complete retroclival hematoma evacuation. At her 3-month follow-up, the patient remained neurologically intact with imaging confirming no residual subdural hematoma. Institutional Review Board approval was obtained for this submission (2018-9379). Patient consent was not obtained as personal identifying information was kept confidential, following guidelines set forth by Institutional Review Board requirements.
