Case ReportsHistopathological findings in a surgically resected thalamic cavernous hemangioma 1 year after 40-Gy irradiation.
Stereotactic radiosurgery is a controversial treatment modality in the management of cerebral cavernous hemangiomas (CHs), and results vary from center to center. Even the interpretation of treatment failure is controversial. It is suggested that the systematic pathological investigation of irradiated specimens could help to resolve the controversy. ⋯ Compared with nonirradiated control CH tissue samples, there was endothelial cell destruction and marked fibrosis with scar tissue formation in the stroma of the treated lesion. The histopathological findings in this specimen were similar to those described in arteriovenous malformations after gamma knife surgery. The results of light microscopic investigations suggest that the ionizing effect of radiation energy evokes vascular and connective tissue stroma changes in CHs as well.

Case ReportsMultiple cerebral aneurysms in a neonate: occlusion and rupture.
Aneurysmal subarachnoid hemorrhage in a neonate is exceedingly uncommon. The authors report the case of a neonate with a large anterior communicating artery aneurysm, accessory left middle cerebral artery aneurysm, and left internal carotid artery (ICA) fusiform aneurysm. ⋯ The large aneurysm was treated with detachable coils and the patient made a significant recovery. Of the 15 case reports of cerebral aneurysms in neonates that have been published, none has contained a description of multiple aneurysms or a discussion of endovascular treatment.

Outpatient gamma knife surgery for vestibular schwannoma: definition of the therapeutic profile based on a 10-year experience.
The purpose of the study was to define the therapeutic profile of outpatient gamma knife surgery (GKS) for vestibular schwannoma (VS) by using sequential tumor volumetry to quantify changes following treatment. ⋯ Outpatient GKS is feasible, effective, and safe. Its therapeutic profile compares favorably with that of microsurgery.

Case ReportsTemporary symptomatic swelling of meningiomas following gamma knife surgery. Report of two cases.
In two patients in whom gamma knife surgery was performed for meningiomas clinically significant volume increases were observed in the first 3 months after treatment. Clinical examination and various imaging studies form the basis of the report in these patients. In each case, the volume increase was temporary.

Relative roles of microsurgery and stereotactic radiosurgery for the treatment of patients with cranial meningiomas: a single-surgeon 4-year integrated experience with both modalities.
The authors sought to assess the respective roles of microsurgery and gamma knife surgery (GKS) in the treatment of patients with meningiomas. ⋯ Both GKS and microsurgery serve important roles in the overall management of patients with meningiomas. Both are safe and effective and provide high degrees of satisfaction when used for differentially selected patients.
