Review Case Reports
Spinal Epidural Inflammatory Pseudotumor: A Case Report and Review of Literature.
Inflammatory pseudotumor is a histologically proven benign tumor-like lesion of unknown etiopathogenesis. It is less commonly found in central nervous system, and least commonly in the spinal canal. Spinal epidural inflammatory pseudotumor is a rarely reported entity. ⋯ It was a radiologic dilemma; thus, complete excision was required for diagnosis and a better outcome.

Review Case Reports
Spontaneous Regression of an Intraparenchymal Cyst Following Deep Brain Stimulator Electrode Implantation: Case Report and Literature Review.
The development of an intraparenchymal cyst following deep brain stimulation (DBS) surgery is an uncommon complication that lacks a clearly defined management strategy. The pathophysiology is not known and may be related to perielectrode edema or cerebrospinal fluid tracking. Previous case reports have described various therapies for symptomatic cysts, including hardware removal or conservative treatment with steroids. ⋯ Only 15 additional cases have been reported in the literature, although the true incidence may be underreported because of varying practices in obtaining postoperative scans. Cysts were identified in symptomatic patients on average 6.2 months after surgery. All symptomatic cysts were treated with hardware removal or steroid therapy. Observation alone may be sufficient when a DBS-associated cyst is identified. More reports are needed to characterize this rare complication.

Primary solitary intracranial malignant melanoma (PIMM) is extremely rare. In 1992, an extensive review of 81 patients with PIMM was undertaken. Imaging studies, microsurgery, and adjuvant therapy have developed considerably over the last 25 years, and targeted therapy recently has been proven successful for metastatic melanoma. These factors could influence current and future clinical PIMM results. ⋯ Gross total removal of the PIMM was the most promising treatment. Currently adjuvant therapy has not been associated with the survival period. To improve clinical outcome, immunotherapy and targeted therapies are likely to become more important.

There is no consensus concerning the management of adult patients with posterior fossa metastasis-associated obstructive hydrocephalus, especially regarding surgical procedures. A literature review was performed to assess the surgical strategy in the management of patients with metastatic brain tumor. ⋯ The Neuro-oncology Club of the French Society of Neurosurgery suggests a prospective assessment of these neurosurgical procedures to compare their safety and efficacy.

Multicenter Study
Tailoring Endoscopic Approach to Colloid Cysts of the Third Ventricle: A Multicenter Experience.
Endoscopic removal of third ventricular colloid cysts has grown in popularity. The biggest issues concern radicality, cure or at least long-term control of the disease, and endoscopic remnants. Technologic advances in instrumentation and introduction of novel tools have greatly improved endoscopic results. Deeper knowledge of surrounding anatomy and awareness that colloid cysts vary in their position (foraminal or retroforaminal) can further improve with the selection of a tailored approach for each patient. ⋯ A traditional precoronal transforaminal approach should be considered only for pure foraminal cysts (group A), as the retroforaminal component is poorly controlled. Retroforaminal cysts (groups B and C) should be resected through a retroforaminal transpellucidum interfornicialis route. A supraorbital transforaminal approach is a more versatile approach suitable for most cases.
