Cysts of the central nervous system : a clinicopathologic study of 145 cases.
ABSTRACT Non-neoplastic, non-inflammatory cysts of the central nervous system may cause symptoms because of pressure, rupture or secondary inflammation. A total of 145 cases of cysts were reviewed during a study period of 12 years. The clinical details and histological features were noted in all cases. During this period 53 epidermoid cysts, 16 dermoid cysts, 38 colloid cysts, 23 arachnoid cysts, 5 neurenteric cysts, 5 ependymal and glial cysts, 2 Rathke's cleft cysts and 3 unclassified cysts were encountered. The possible histogenesis is also discussed.

ABSTRACT: The authors of this retrospective review and analysis of the literature cover an institutional series of neurenteric cysts of the central nervous system in children treated in the magnetic resonance imaging era during a 14-year period. Sixteen patients 20 days to 14 years of age are described. The most frequent signs and symptoms at presentation were acute spinal cord compression (11 patients), paresis of a cranial nerve (two patients), meningitis or infection (two patients), and intracranial hypertension (one patient). The locations of the cysts were as follows: in the spinal canal in 12 patients (75%), the clivus in two (12.5%), the cavernous sinus in one (6%), and the craniocervical junction in one (6%). The most common location was the ventral aspect of the spinal canal (seven patients). Associated spinal deformities were found in five patients. All patients underwent surgery, with a posterior approach used in all of the spinal cases. Total resection was achieved in 12 of the 16 cases and partial resection in four. Of the four patients who underwent subtotal resection, the cyst recurred in three, requiring further surgery. Neurenteric cysts are uncommon congenital anomalies that can present acutely in the pediatric population. Total removal is usually possible and is associated with a good prognosis.Journal of Neurosurgery 01/2006; 103(6 Suppl):512-23. · 2.96 Impact Factor
Chapter: Neurenteric Cysts[show abstract] [hide abstract]
ABSTRACT: Neurenteric or enterogenous cysts are uncommon congenital lesions that result from displaced elements of the alimentary canal and are commonly encountered in the posterior mediastinum. These cysts can occur at any level of the neuraxis from the posterior clinoid to the coccyx; they are most commonly found in the lower cervical and upper thoracic regions [1–4]. The lesions are generally located ventral to the spinal cord and at the cervicomedullary junction [1, 5].12/2007: pages 475-485;
