Gamma knife radiosurgery (GKRS) has been established as an effective and safe treatment for intracranial schwannoma. However, serious complications can occur after GKRS, including hydrocephalus. The pathophysiology and risk factors of this disorder are not yet fully understood. The objective of the study was to assess potential risk factors for hydrocephalus after GKRS. ⋯ Because hydrocephalus is curable, patients should be closely monitored for the development of this disorder after GKRS. In particular, patients with intracranial schwannomas with irregular enhancement patterns or cysts should be meticulously observed.

Osteopetroses are a heterogeneous group of heritable disorders characterized by increased bone density as the result of defective osteoclast-mediated bone resorption. The autosomal-dominant osteopetrosis type I (ADO-I) is defined by the presence of osteosclerosis involving mainly the skull bones, variably associated with compression of the foramina of cranial nerves and vascular structures, hypertelorism, exophthalmos, and less commonly with hydrocephalus, pseudotumor, and Chiari malformation type I. ⋯ After reviewing the literature, we can confirm that ours was the second case of an adult ADO-I patient associated with anterior ethmoidal meningoencephalocele, the first one needing a combined treatment of the encephalocele and hydrocephalus. Because ADO-I is a rare disease with a wide spectrum of clinical manifestations, our case can represent a prototype for the future management of similar cases.

Patients undergoing carotid endarterectomy (CEA) are at risk of developing ipsilateral stroke or transient ischemic attacks (TIAs). In this study, we explored factors associated with development of these events following CEA in patients with long-term follow-up. ⋯ Our data suggest that family history of stroke, cigarette smoking, and atrial fibrillation are independent risk factors for developing ischemic events after CEA. In patients with asymptomatic presentation, female gender is also a risk factor. Identification of patients at risk is critical for tailored postoperative patient management and patient education.

The incidences of metastatic brain tumors from gynecologic cancer have increased. The results of Gamma Knife surgery (GKS) for the treatment of patients with brain metastases from gynecologic cancer (ovarian, endometrial, and uterine cervical cancers) were retrospectively analyzed to identify the efficacy and prognostic factors for local tumor control and survival. ⋯ GKS is effective for control of tumor progression in patients with brain metastases from gynecologic cancer, and may provide neurologic benefits and preservation of the quality of life.

Traumatic brain injury (TBI) is one of the major challenges in health care, representing the third most frequent cause of death. Current optimal management is based on a progressive, target-driven approach combining both medical and surgical treatment strategies. Here we describe cisternostomy, an emerging surgical treatment for the treatment of TBI. ⋯ In the current common practice, the surgical measures for TBI include external ventricular drainage insertion and decompressive craniectomy. There is evidence that both of these measures reduce intracranial pressure but the effect on the outcome, particularly in the long term, is equivocal. A new line of evidence supports cisternostomy as an emerging surgical treatment for TBI.
