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.

✓ Since its description by Dandy in 1922, several techniques have been used to perform third ventriculostomy under endoscopic control. Except for the blunt technique, in which the endoscope is used by itself to create the opening in the floor of the third ventricle, the other techniques require more than one instrument to perforate the floor of the ventricle and enlarge the ventriculostomy. The new device described is a sterilizable modified forceps that allows both the opening of the floor and the enlargement of the ventriculostomy in a simple and effective way.The new device has the following characteristics: 1) the tip of the forceps is thin enough to allow the easy perforation of the floor of the ventricle; 2) the inner surface of the jaws is smooth to avoid catching vessels of the basal cistern; and 3) the outer surface of the jaws has indentations that catch the edges of the opening to prevent them from slipping along the instrument's jaws. The ventricle floor is opened by gentle pressure of the forceps, which is slowly opened so that the edges of the aperture are caught by the distal outer indentation of the jaws, leading to an approximately 4-mm opening of the floor. This device has been used successfully in 10 consecutive patients.This new device allows surgeons to perform third ventriculostomy under endoscopic control in a very simple, quick, and effective way, avoiding the need for additional single-use instruments.

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 tapeworm Spirometra mansonoides infects man worldwide, particularly in Asian countries. Rarely, the central nervous system is involved; such a case is presented here. In the total of 12 reported cases, including the case described, the worm presented clinically as a mass suspicious for neoplasm or chronic abscess cavity. Surgical removal was invariably curative in each case. Although infrequent, the possibility of tapeworm infection should be entertained in the evaluation of intracranial masses in patients who have visited exotic locales.

✓ Local recurrence developed 6 years after the initial resection of an intraspinal meningeal tumor that originally was thought to be an angioblastic meningioma. Histological review of the pathology led to a change of that diagnosis to one of mesenchymal chondrosarcoma. The recurrent vascular tumor was embolized, then totally excised. Because this tumor had malignant features, the patient received irradiation and chemotherapy. No evidence of regrowth has been observed during a period of more than 4 years. Mesenchymal chondrosarcomas of the central nervous system and their treatment are reviewed.

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.

✓ Two patients are reported who had intracerebral mass lesions composed of hemangioma and glial neoplasm. After excision, one recurred as an oligodendroglioma, and the remnant of the other remained static over a 5-year period. These lesions may represent a subgroup of cerebral hemangiomas that have the biological potential for future glial neoplastic growth. Reference is made to experimental work with polyoma virus which can induce cavernous hemangiomas in the central nervous system in mice, and which is a papovavirus. Other papovaviruses can induce ependymomas in hamsters.

✓ Superficial siderosis is a rare condition characterized by deposition of hemosiderin in the leptomeninges and in the subpial layers of the brain and spinal cord. It is associated with cerebrospinal fluid abnormalities consistent with recurrent bleeding into the subarachnoid space. The usual symptoms are hearing loss, ataxia, spastic paraparesis, sensory and sphincter deficits, and mental deterioration. A case is presented of severe superficial siderosis of the central nervous system in a 51-year-old man who had suffered a brachial plexus injury at the age of 20 years. The diagnosis was made by means of magnetic resonance imaging 16 years after the initial symptoms, which comprised bilateral hearing loss and anosmia. Subarachnoid bleeding was due to traumatic pseudomeningocele of the brachial plexus, a very unusual cause of superficial siderosis. This case is interesting insofar as the surgical treatment prevented further bleeding and possibly progression of the disease.
