BACKGROUND
Intracranial ependymal cysts are rare lesions generally located in the cerebral parenchyma, juxtraventricular region, or subarachnoid space; but no case of a purely intraventricular ependymal cyst has been reported.
CASE REPORT
A case of intraventricular ependymal cyst presenting with symptoms of psychosis is reported. The patient's symptoms resolved almost completely following endoscopic resection of the cyst. The embryologic basis of the development of an ependymal cyst inside the ventricle and its histologic characteristics are discussed. Possible mechanism of psychosis in this case is also discussed.
CONCLUSION
Minimally invasive techniques, as in this case, may be useful in refractory psychotic cases with cystic lesions.
背景
颅内室管膜囊肿是罕见病变，通常位于脑实质、脑室旁区域或蛛网膜下腔；但尚无纯脑室内室管膜囊肿的病例报道。
病例报告
报告1例以精神病症状为表现的脑室内室管膜囊肿病例。囊肿经内镜切除后，患者症状几乎完全缓解。文中讨论了脑室内室管膜囊肿发生的胚胎学基础及其组织学特征。还讨论了该病例中精神病可能的发病机制。
结论
如本病例中的微创技术，可能对伴有囊性病变的难治性精神病病例有用。
