Traumatic injury to the posterior fossa

Traumatic injury to the posterior fossa is a complex pathologic condition because of the great heterogeneity of lesions present. Treatment of primary brain injuries and prevention of secondary brain injuries is the mainstay of management. It is imperative to recognize traumatic lesions of the posterior fossa early because of the occurrence of rapid neurologic decline. The decision regarding whether or not to proceed with surgical intervention depends on the patient's clinical condition, neurologic status, and imaging findings. Nonoperative management should be considered only if the patient is fully conscious and the associated posterior fossa lesions are small with little or no mass effect.
