Traumatic Hematoma of the Posterior Fossa

Abstract

Posterior fossa injury is rare, occurring in less than 3 % of head injuries. We retrospectively reviewed patients' clinical and radiological findings, management, and outcomes. The aim of the present study was to investigate the features of posterior fossa hematoma, including posterior fossa epidural hematoma (EDH), posterior fossa subdural hematoma (SDH), and intracerebellar hematoma. From January 1995 to January 2009, 4,315 patients with head trauma were hospitalized at our institution. The -present study focused on 41 patients (1.0 %) with traumatic hematomas of the posterior fossa. Eighteen patients had EDH, 10 patients had SDH, and 17 patients had intracerebellar hematomas. In each type of injury, occipital bone fractures were seen in many patients, and hematoma enlargement was often observed within a few days of the injury. In addition, a high frequency of associated lesions and a high poor outcome rate were features of intracerebellar hematomas and -posterior fossa SDH. The present study suggests that repeat CT imaging and careful management are necessary until the lesion is stabilized, and patients showing lesions with mass effects should therefore be immediately treated with surgery.

Posterior fossa acute extradural hematoma in children: Review and management guidelines

“…It accounts for less than 0.13% to 1.9% of all traumatic head injuries. [ 2 3 ] The rarity is because of the early ossification and due thickness of the basioccipital bone, resulting in less amount of fracture as compared to supratentorial counterparts. PFEDH accounts for 4%–12.9% of all acute extradural hematoma cases.…”

Surgical Treatment of Severe Traumatic Brain Injury

“…Compared with the aforementioned traumatic brain injuries, traumatic posterior fossa mass lesions are rare. In a recent retrospective review of 4315 patients of hospitalized TBI patients, only 41 (1%) were noted to have posterior fossa hematomas [50]. In these 41 patients, there were 18 patients with posterior fossa EDH, 10 with SDH, and 17 with intracerebellar hematoma [50].…”

EDH is the most common posterior fossa lesion reguiring surgery, followed by SDH and intracerebellar hemorrhage [7].…”

Akut Posterior Fossa Subdural Hematom

“…supratentorial subdural hematomas (SDHs) are one of the commonest diseases encountered in the neurosurgical practice. Takeuchi and colleagues [8] analyzed 4315 patients with head trauma from 1995 to 2005. They found that 41(1%) their patients had traumatic hematomas of the posterior fossa and of those, only 10 had SDHs.…”
