Review Case Reports
Solitary Primary CNS Lymphoma mimicking third ventricular colloid cyst- case report and review of the literature.
Primary central nervous system lymphoma is a rare malignant tumor of the central nervous system. It is associated with poor prognosis and accounts for 0.7%-0.9% of all lymphomas and only 0.3%-1.5% of intracranial tumors. Typically, these lesions are in the cerebral white matter near the corpus callosum, the central gray matter, the basal ganglia-thalamus-hypothalamic region, the posterior fossa and the periventricular region. Only 2 cases with pure third ventricular lymphoma have been reported in the literature. ⋯ Eleven months after surgery, the patient is fully consciousness and oriented, with no memory issues or neurologic deficit. She is back to her baseline activities. We are reporting this case for the rarity of the disease and the unusual location of it.

Review Case Reports
Extracranial-intracranial bypass for cerebral vasculitis after graft-versus-host disease: case report and literature review.
Cerebral vasculitis owing to chronic graft-versus-host disease (GVHD) is very rare. To our knowledge, only 2 cases have been reported. We describe the first case of superficial temporal artery-middle cerebral artery (STA-MCA) bypass for cerebral vasculitis owing to GVHD. ⋯ Although the mechanism of cerebral vasculitis after chronic GVHD is not known, cerebral vasculitis that causes cerebrovascular disease long after bone marrow transplantation should be considered. In this case, an STA-MCA bypass was efficient for the repeated ischemic attacks owing to cerebral vasculitis. Moreover, it is important to select the optimal recipient vessels to area originated neurologic symptoms.

Review Historical Article
The history of and controversy over Kambin's Triangle: A historical analysis of the lumbar transforaminal corridor for endoscopic and surgical approaches.
The transforaminal corridor in the lumbar spine allows access to the traversing and exiting nerve roots, the thecal sac, and the intervertebral disc space. Surgeons performing midline and minimally invasive approaches for lumbar interbody fusion access the disc space within the boundaries created by the exiting root of a segment and the traversing root after a complete facetectomy and removal of the pars interarticularis and lamina. Endoscopic surgeons and interventional pain management physicians approach the lumbar segment through a similar corridor, but with the bony anatomy intact. ⋯ The objective of the current work is to add clarity to the various lumbar transforaminal corridors. The term Kambin's triangle should be limited to percutaneous access to the disc space for endoscopic procedures in the intact spine and should not be applied to transforaminal lumbar interbody fusion after laminectomy and facetectomy. Instead, the term expanded transforaminal corridor should be applied.

Review Biography Historical Article
Did Ibn Zuhr (Avenzoar) postulate before Vesalius that liquid collects in ventricles in the hydrocephalus?
This study aimed to present and evaluate the part of Avenzoar's Liber Teisir that pertains to hydrocephalus. Avenzoar was an Andalusian physician prominent in the history of medicine because of the broadness of his observations and original methods. His most important work is recognized to be the Al-Taysīr fī al-Mudāwāt wa al-Tadbīr (On Preventive Regimen and Treatment), and its Latin version, Alteisir scilicet regiminis et medelae, which was in use for centuries in Europe. ⋯ Avenzoar might have noted one of the earliest records on the clinical state called idiopathic adult hydrocephalus and postulated liquid collection in the ventricles of the brain in hydrocephalus before Vesalius.

Repair of a transclival meningocele through a transoral approach: Case report and literature review.
Transclival meningoceles and related primary spontaneous cerebrospinal fluid leaks at the clivus are extremely rare lesions, with only a few cases reported in the literature. ⋯ Transclival meningocele should be considered in patients with spontaneous cerebrospinal fluid rhinorrhea. The existing classification of meningoencephaloceles based on the location of the defect in the cranium should probably be reconsidered, taking into consideration the described entity.
