Central neurocytoma (CN) is an uncommon brain tumor arising primarily in the lateral ventricular near the foramen of Monro and approximately accounting for 0.1-0.5% of all primary tumors of the central nervous system. We report a case of neurocytoma located in the fourth ventricle and extended into the third ventricle. The tumor is composed of uniform round cells with immunohistochemical features of neuronal differentiation. CN is probably a differential diagnosis with oligodendrogliomas and ependymoma. Morphology and immunohistochemical findings associated with clinical and radiological characteristics may support CN diagnosis.

Pilomyxoid astrocytoma (PMA) is a rare central nervous system tumor that has been included in the 2007 World Health Organization Classification of Tumors of the Central Nervous System. Due to its more aggressive behavior, PMA is classified as Grade II neoplasm by the World Health Organization. PMA predominantly affects the hypothalamic/chiasmatic region and occurs in children (mean age of occurrence = 10 months). We report a case of a 24-year-old man who presented with headache, nausea, and vomiting. Brain CT and MRI revealed a mass occupying only the third ventricle. We performed partial resection. Histological findings, including monophasic growth with a myxoid background, and absence of Rosenthal fibers or eosinophilic granular bodies, as well as the strong positivity for glial fibrillary acidic protein were consistent with PMA.

The Brain

The introduction of Shiga toxin into the ventricular system of the brain with major location in the third ventricle resulted in a response similar to that following the administration of the toxin either intravenously or by cross-circulation. The intravenous administration at the dosage level employed would have elicited no response. These observations lend support to the hypothesis that Shiga toxin activates some mechanisms in the central nervous system which are capable of producing visceral lesions. These mechanisms are those which control the vasomotor components of homeostasis. This hypothesis permits an explanation of the proximo-distal and intramural features of the lesion.

The Difference

A previous study demonstrated that the threshold dose of intra-arterial angiotensin II required to induce a pressor response in the rat was significantly lower when the drug was administered into the carotid artery than when administered into the abdominal aorta. This result was interpreted to indicate that part of the increase in arterial pressure produced by low concentrations of blood-borne angiotensin in this species was the result of an effect on structures in the central nervous system selectively accessible via the carotid vascular bed. The purpose of the present study was to establish more precisely the site of the pressor action of angiotensin within the central nervous system. The central component of the pressor effect of angiotensin was quantified as the difference in pressor responses to intracarotid and intra-aortic infusions of angiotensin II (delta c-a). In conscious rats, delta c-a was attenuated by administration of the angiotensin antagonist, saralasin, into the third cerebral ventricle. In rats with chronic electrolytic lesions of the anteroventral third ventricle (AV3V), delta c-a was abolished. Periventricular structures surrounding the third ventricle appear to mediate the central component of the pressor action of blood-borne angiotensin in the rat.

Frequent Site

Neurocysticercosis is the most frequently observed parasitosis of the central nervous system worldwide. The fourth ventricle is the most frequent site of intraventricular infestation, a location that carries a higher risk for CSF blockage and intracranial hypertension due to CSF blockage. A great number of patients become shunt dependent which carries a poorer prognosis. We report on a case of a patient with symptomatic obstructive hydrocephalus due to cysticercus in the fourth ventricle where an endoscopic approach via a frontal burr hole was performed. Although there is no consensus in the literature for the optimal treatment of this disease, this method seemed adequate for treatment of fourth ventricle cysticercosis in patients with hydrocephalus, aqueductal and foramen of Monro dilatations.

Neuroepithelial Cysts

✓ Thalamic neuroepithelial cysts are rare lesions of the central nervous system. Surgical management of these lesions has varied and yielded mixed results. The authors identified 10 reported cases in the literature, five of which involved symptomatic lesions. The authors present three unique cases of symptomatic thalamic neuroepithelial cysts associated with hydrocephalus, which were all successfully treated using endoscopic third ventriculostomy and fenestration of the cyst into the third ventricle.

Classification Of Tumors

This chapter presents the most up-to-date classification of tumors of the nervous system, based on the histological appearance of the neoplasm and also on information derived from cytogenetics and molecular biology, now recognized worldwide as increasingly important for more precise diagnosis, prognosis, and therapeutic guidance. The chapter provides a detailed morphologic description of each major tumor type, with numerous illustrations of macroscopic and microscopic lesions. First we consider primary tumors of the nervous system, including those derived from neuroepithelial tissue (astrocytic, oligodendroglial, ependymal, neuronal, and glioneuronal), pineal tissue, peripheral nerve sheath, and meninges. Next lymphomas, hematopoietic neoplasms, and secondary (metastatic) neoplasms are described.

Schwannoma is a benign encapsulated tumor that originates from the Schwann cells lining nerve fibers outside the central nervous system. We report a rare case of schwannoma that arose from the left arythenoid cartilage The patient underwent excision of the mass through microlaryngeal endoscopic procedure. No recurrence was observed during follow-up.
