Comparative Study Clinical Trial
Brainstem cavernomas: long-term results of microsurgical resection in 52 patients.
To review the natural history and the long-term results of microsurgical resection of brainstem cavernous angiomas operated on in one institution. ⋯ Surgical resection is recommended for superficial lesions and for lesions that can be reached through the anterolateral pontine surface. Surgery is also recommended for symptomatic cavernomas with a satellite subacute hematoma.

Comparative Study
Functional outcome after central corpectomy in poor-grade patients with cervical spondylotic myelopathy or ossified posterior longitudinal ligament.
We studied the long-term functional outcome in poor-grade patients (Nurick Grades 4 and 5) with cervical spondylotic myelopathy (CSM) or ossified posterior longitudinal ligament after central corpectomy (CC). We sought to determine whether there were any prognostic factors that could predict functional outcome in these patients. ⋯ More than three-fourths of patients with poor-grade CSM improve in their functional status after CC, with nearly 24% of patients obtaining a cure. Because patients with a duration of myelopathic symptoms of 12 months or less had the best functional outcome, early decompressive surgery should be offered to patients with poor-grade CSM.

Case Reports
A highly vascular intracranial solitary fibrous tumor treated with radiotherapy and toremifene: case report.
A case of an unusual intracranial solitary fibrous tumor with features of high vascularity and resultant difficulty at resection is presented. The use of surgery, radiotherapy, and toremifene has been successful with no recurrence after 18 months. ⋯ The use of surgery, radiotherapy, and toremifene in treatment of a vascular intracranial solitary fibrous tumor has been successful and warrants further research.

Comparative Study Clinical Trial
Gamma knife radiosurgery for trigeminal neuralgia.
The purpose of this study was to assess outcomes in patients treated with gamma knife radiosurgery for trigeminal neuralgia. ⋯ Gamma knife radiosurgery established durable pain relief in 61% of patients with medically refractory idiopathic trigeminal neuralgia. A longer follow-up period is necessary to fully assess the incidence of late complications and recurrences.

Case Reports Comparative Study
Neural damage caused by cerebral hyperperfusion after arterial bypass surgery in a patient with moyamoya disease: case report.
The prognosis of cerebral hyperperfusion syndrome after vascular reconstructive surgery, including extracranial-intracranial arterial bypass, is not poor unless intracerebral hemorrhage develops secondary to hyperperfusion. ⋯ The current case suggests that cerebral hyperperfusion after vascular reconstructive surgery can cause irreversible neural damage, which results in cognitive impairment.
