Enterogenous Cyst and Glioblastoma: A Brief Histopathological Review of Two Uncommon Cystic Lesions of the Central Nervous System
Cisto entérico e glioblastoma: Uma breve revisão histopatológica de duas lesões císticas incomuns do sistema nervoso central
Abstract
Intracranial cystic lesions are common findings in cerebral imaging and might represent a broad spectrum of conditions. These entities can be divided into nonneoplastic lesions, comprising Rathke cleft cyst, arachnoid cyst, and colloid cyst, as well as neoplastic lesions, including benign and malignant components of neoplasms such as pilocytic astrocytoma, hemangioblastoma, and ganglioglioma. Surgical resection and histological evaluation are currently the most effective methods to classify cysts of the central nervous system. The authors report two uncommon cases presenting as cystic lesions of the encephalic parenchyma—a enterogenous cyst and a glioblastoma—and discuss typical histological findings and differential diagnosis.
Resumo
Lesões císticas intracranianas são achados comuns em imagens cerebrais e podem representar um amplo espectro de condições. Essas entidades podem ser divididas em lesões não neoplásicas, compreendendo cisto da bolsa de Rathke, cisto aracnoide e cisto colóide, e lesões neoplásicas, incluindo componentes benignos e malignos de neoplasias, como astrocitoma pilocítico, hemangioblastoma e ganglioglioma. A ressecção cirúrgica e a avaliação histológica são atualmente os métodos mais eficazes para classificar os cistos do sistema nervoso central. Os autores relatam dois casos incomuns que se apresentam como lesões císticas do parênquima encefálico, um cisto entérico e um glioblastoma, e discutem achados histológicos típicos e diagnósticos diferenciais.
