Traumatic Posterior Fossa Hematoma, A Rare Entity: Study of 21 Cases

Background Traumatic posterior fossa hematoma is a rare entity. Traumatic posterior fossa hematomas are associated with considerable morbidity and mortality and their surgical management remained controversial. Methods From August 2011 to August 2017, approximately 5,100 patients with head injury were managed. Authors reviewed clinical and radiological findings, management criteria, and outcome of posterior fossa hematoma in 21 patients. Results Out of 21 cases, 13 survived with our management. The Glasgow Coma Scale (GCS) on admission was higher in favorable group than in poor outcome group. Factors associated with Glasgow Outcome Scale in two groups were status of fourth ventricle, basal cisterns, subarachnoid hemorrhage (SAH), hematoma volume, and their location (hemispheric or midline). Similarly, associated supratentorial lesions, age, gender, lesions in other parts of body, and timing from injury to reporting to hospital were taken into consideration. Conclusion The factors correlated with patient outcome were age, sex, mode of injury, GCS at admission, associated intracranial hematomas, associated SAH, hematoma volume, hematoma location, basal cisterns, status of fourth ventricle, and associated multiple injuries on other body parts. It is hereby concluded that timely surgical intervention should be employed whenever indicated without delay. Posterior fossa hematomas were rarely observed in the pediatric age group.

Chronic subdural hematoma of the posterior fossa associated with cerebellar hemorrhage: report of rare disease with MRI findings

Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, occurring mostly during anticoagulation therapy. The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma.
