The most common sellar pathology that merits neurosurgical attention is the pituitary adenoma. However, some developmental, inflammatory, and neoplastic lesions may primarily or secondarily involve the sella, mimicking pituitary tumors. Advances in imaging and endocrinological assessment have helped in the recognition of these less common sellar, supra sellar pathologies, which may occasionally create confusion in management.

Background: Although extraparenchymal Neurocysticercosis (NCC) is well established, presentation in the suprasellar space is rare. When presenting in the suprasellar space, the imaging characteristics may mimic more common lesions including craniopharyngioma and Rathke cleft cyst depending on the life cycle of the parasite. Although antiparasitic medical therapy may be effective for viable NCC, it is not routinely employed for calcified NCC. Read More

Astrocytes, the most numerous cells of the central nervous system, exert critical functions for brain homeostasis. To this purpose, astrocytes generate a highly interconnected intercellular network allowing rapid exchange of ions and metabolites through gap junctions, adjoined channels composed of hexamers of connexin (Cx) proteins, mainly Cx43. Functional alterations of Cxs and gap junctions have been observed in several neuroinflammatory/neurodegenerative diseases. Read More

Introduction: Hemangioblastomas are rare, histologically benign, highly vascularized tumors of the brain, the spinal cord, and the retina, occurring sporadically or associated with the autosomal dominant inherited von Hippel-Lindau (VHL) disease. Children or adults with VHL disease have one of > 300 known germline mutations of the VHL gene located on chromosome 3. They are prone to develop hemangioblastomas, extremely rarely starting at age 6, rarely at age 12-18, and, typically and almost all, as adults. Read More

Persistent inflammation has been identified as a contributor to aging-related neurodegenerative disorders such as Alzheimer's disease. Normal aging, in the absence of dementia, also results in gradual cognitive decline and is thought to arise, in part, because of a chronic pro-inflammatory state in the brain. Toxoplasma gondii is an obligate intracellular parasite that establishes a persistent, asymptomatic infection of the central nervous system (CNS) accompanied by a pro-inflammatory immune response in many of its hosts, including humans and rodents.

The glycosylated mucin domain of the cyst wall glycoprotein CST1 is heavily stained by agglutinin, a lectin that binds to -acetylgalactosamine. The cyst wall is also heavily stained by the chitin binding lectin succinylated wheat germ agglutinin (s-WGA), which selectively binds to acetylglucosamine-decorated structures. Here, we tracked the localization of acetylglucosamine-decorated structures that bind to s-WGA in immature and mature cysts. Read More

Surgical options for symptomatic intracranial arachnoid cysts include cyst shunting and microscopic or endoscopic fenestration. We advocate a microsurgical keyhole approach for the durable fenestration of middle fossa arachnoid cysts, taking advantage of the superior magnification, depth perception, and illumination of the operating microscope, as well as the ability to use bimanual surgical technique and variable suction to ensure safe manipulation of arachnoid membranes and fenestration of these lesions into the deep cisterns. Key technical aspects of this approach demonstrated in this video (Video 1) include performance of a dime-sized temporal craniotomy; strict microsurgical technique with sharp dissection via a No. Read More

Background: Rathke's Cleft Cysts (RCCs) are rare epithelial cysts arising from remnants of the Rathke pouch in the pituitary gland. A subset of these lesions enlarge and produce a mass effect with consequent hypopituitarism, and may result in visual loss. Moreover, some RCCs with a high intra-cystic protein content may mimic cystic pituitary adenoma, which makes their differential diagnosis ambiguous. Read More

Introduction: Nasal dermoids with intracranial extension are benign lesions that can have life-threatening consequences, as a nasal punctum may serve as a portal of entry for infection into the central nervous system. The surgical management of these lesions can be challenging, as the extracranial and intracranial cysts and sinus tract must be resected to prevent recurrence, and the surgery must be carried out with an acceptable esthetic result.

Technique: The authors present a technique for the resection of nasocranial dermoids that eliminates the need to remove and replace the frontonasal segment. Read More

Background And Purpose: Because it can be difficult to discriminate between a Rathke cleft cyst and cystic craniopharyngioma by conventional MR imaging alone, we investigated whether contrast-enhanced 3D T2-FLAIR MR imaging at 3T helps to distinguish a Rathke cleft cyst from a cystic craniopharyngioma.

Materials And Methods: We evaluated pre- and postcontrast T1-weighted and 3D T2-FLAIR images of 17 patients with pathologically confirmed Rathke cleft cyst ( = 10) or cystic craniopharyngioma ( = 7). All underwent 3T MR imaging studies before surgery. Read More
