Endoscopic evacuation of hypertensive putaminal hemorrhage guided by the 3D reconstructed CT scan: a preliminary report.
The minimally invasive procedure is the trend in nowadays neurosurgical techniques. We designed a new targeting method using three-dimensional (3D) reconstructed CT images combining neuroendoscope for hypertensive putaminal hemorrhage (HPH). ⋯ Use of the 3D reconstructed CT imaging technique combining neuroendoscope may add as a minimally invasive, economic, and timesaving way for targeting HPH. It also serves as a reliable and useful alternative for hospitals without stereotactic or navigating modalities. However, further prospective studies were needed to clarify its efficacy and safety compared to conventional surgeries.

Case ReportsPenetrating head injury by a stone: case report and review of the literature.
Traumatic intracranial penetration of foreign objects of non-missile intracranial nature rarely occurs. Haemorrhages, major vascular injury and contusions can be causes of death in early stage, epileptic seizures and infections are possible complications in later stages. ⋯ In the present study, we report a rare case of traumatic intracranial stone as a foreign object. A brief review of the literature is presented.

Case ReportsPhase-contrast cine MRI revealing en valve mechanism in spontaneous third ventriculostomy: report of a case and literature review.
A 50-year-old epileptic woman affected by hydrocephalus due to aqueductal stenosis was admitted to the hospital because of headache, dysarthria, and mild lateral pulsion. Cranial computed tomography (CT) revealed left cerebellar hemorrhage. Subsequent magnetic resonance imaging (MRI) of the brain demonstrated an enlarged ventricular system unchanged from prior studies. ⋯ Spontaneous third ventriculostomy (STV) was diagnosed on the basis of these findings. STV is a rare condition occurring in chronic obstructive hydrocephalus patients as a result of longstanding pulsations against the walls of the third ventricle, the floor in particular. We reviewed the literature to establish which imaging and clinical findings could improve the identification of STV in patients affected by obstructive hydrocephalus.

Case ReportsSpinal cord syrinx expansion following acquired Chiari malformation decompression: case report.
Chiari malformation development after lumboperitoneal (LP) shunting for pseudotumor cerebri is a recognized phenomenon. Treatment options for an acquired Chiari malformation include observation, LP shunt revision or ligation, ventriculoperitoneal (VP) shunt placement, and suboccipital decompression. The authors describe a case of suboccipital decompression of an acquired Chiari malformation that resulted in the development of a spinal cord syrinx. ⋯ An enlarging spinal cord syrinx can occur following the suboccipital decompression of an acquired Chiari malformation in pseudotumor cerebri patients. Careful consideration to VP shunting should be given prior to posterior fossa decompression in such cases in an attempt to avoid syrinx development.

Case Reports Comparative StudyDifferentiating radiation necrosis from tumor recurrence in high-grade gliomas: assessing the efficacy of 18F-FDG PET, 11C-methionine PET and perfusion MRI.
The authors analyzed the characteristics of perfusion magnetic resonance imaging (MRI), (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) and (11)C-methionine (MET) PET to compare the efficacies of these modalities in making the distinction between radiation necrosis and tumor recurrence of high-grade glioma. ⋯ A quantitative rCBV as calculated from a perfusion MRI scan might be superior to the L(max)/R(max) ratio as derived from (18)F-FDG and (11)C-MET PET in order to distinguish a recurrence of high-grade glioma from radiation necrosis.
