  • Hemilaminectomy for the Removal of Intraspinal Tumors

    目的:探讨半椎板切开入路切除椎管内肿瘤的优缺点。方法:回顾性分析2004~2006年经手术切除病理证实的椎管内肿瘤196例的临床资料。其中80例行了半椎板入路肿瘤切除,与同期的116例全椎板切除病人进行比较。结果:半椎板切除病人手术住院时间明显缩短,术后起床反应轻微,远期效果较全椎板好,对脊柱的稳定性影响小。结论:单侧半椎板入路切除椎管内肿瘤损伤小,最有利于脊柱稳定性的维持。病人手术后住院时间短,反应轻微,远期疗效好。但也有暴露局限的缺点.

  • Clinical features and treatment of central nervous system embryonal tumor, not otherwise specified

    ObjectiveTo review the clinical records of patients with central nervous system (CNS) embryonal tumors, not otherwise specified (NOS); and summarize their clinical features, diagnosis, and treatment.MethodWe reviewed the data of patients with intracranial tumors admitted to Department of Neurosurgery of West China Hospital, Sichuan University from January 2014 to December 2016, and retrospectively analyzed the clinical features, diagnosis, and treatment of seven patients with CNS embryonal tumors, NOS.ResultsThere were 4 males and 3 females, and the mean age was 25.4 years old. The tumor was located in cerebral hemisphere in 5 patients, and in third ventricle in 2. Clinical presentation included headache, nausea, and vomiting due to intracranial hypertension, and focal neurological signs. All patients underwent craniotomy for tumor resection and postoperative pathology confirmed CNS embryonal tumor, NOS. The patients were followed up for 6 months to 3 years, and 2 patients died during follow-up.ConclusionsCNS embryonal tumor, NOS is malignant intracranial lesion, and has been enlisted as a separate entity under classification of CNS embryonal tumors. It has its unique radiological features, including rare occurrence of perilesional edema, cystic changes, and clear demarcation. Through comprehensive treatment including surgical resection, chemotherapy, and radiation therapy, patients can enjoy prolonged survival and improved quality of life.

  • Intraoperative Neurophysiological Monitoring During Microsurgery for Solid Medullary Hemangioblastoma

    目的 探讨显微切除延髓实体性血管母细胞瘤术中电生理监测的意义。 方法 2007年7月-2009年8月,在电生理监测下显微切除13例延髓实体性血管母细胞瘤,观察切除程度、死亡率及术后脑干功能,并对电生理监测下的手术技巧进行讨论总结。 结果 完全切除13例延髓实体性血管母细胞瘤,术后因呼吸功能衰竭死亡1例,6个月脑干机能状态较术前保持或改进10例。 结论 延髓实体性血管母细胞瘤切除术中行神经电生理监测有助于提高手术效果,改善预后。

  • MRI manifestations of intracranial solitary fibrous tumor

    Objective To study the MRI features of intracranial solitary fibrous tumor (ISFT). Methods MRI features of 8 patients with ISFT treated between December 2010 and December 2015 were retrospectively analyzed and relavent literatures about its neuroimaging were reviewed. Results All the 8 cases were single solitary fibrous tumor (SFT), among which 4 arose from and beneath the tentorium, 2 in the left cerebellopontine angle, 1 in jugular foramen region and 1 in saddle area. All tumors had clear boundary, 3 were oval or round, 2 were irregular-shaped, 2 were lobulated and 1 was dumb-bell shaped. Tumor size ranged from 35 to 65 mm. On pre-contrast MRI, 5 cases were mixed with hypo to hyperintense signals on (T1 weighted image) T1WI and heterogeneous on (T2 weighted image) T2WI. The rest 3 cases were featured by solid and cystic components; the solid component was hypo to isotense on T1WI and hypointense on T2WI while the cystic areas, which were not enhanced in the postcontrast images, were hypo and hyperintense on T1WI and T2WI, respectively. All the areas with low T2 signal intensity were strongly enhanced after gadolinium administration. Flow-empty actions, peritumoral edema and “dural tail” sign was found in 6, 3 and 0 cases, respectively. All the 3 cystic cases were confirmed as malignant ISFT while the rest 5 were benign. Conclusions MRI manifestation of ISFT has some characteristics. There may exist some correlations between the intratumoral cyst and malignant potential. However, the diagnosis of ISFT remains dependent on histopathology.

  • Clinical characteristics and prognostic factors of pediatric diffuse brain stem glioma

    ObjectiveTo explore the clinical features and prognostic factors of diffuse brain stem glioma in children. MethodsA retrospective analysis was conducted on pediatric diffuse brain stem glioma diagnosed by pathology in West China Hospital of Sichuan University between January 2016 and May 2019. The demographic data, clinical manifestations, MRI findings, pathological results, and treatment were included in the prognosis study.ResultsA total of 39 cases of pediatric diffuse brain stem glioma confirmed by pathology were enrolled, including 21 males and 18 females aged between 3 and 14 years with an average of (8.1±2.8) years and mostly between 5 and 10 years (29 cases). The mean maximum diameter of gliomas was (4.46±0.81) cm. Among the 39 cases, there were 15 cases complicated with hydrocephalus and 16 cases whose tumors completely surrounded the basilar artery. The median survival time was 6 months. The one-year survival rate was 15.4%, and the two-year survival rate was 5.1%. Univariate analyses showed that the tumor enhancement and completely enclosed basilar artery had significant impact on the prognosis (P<0.05). Multiple Cox regression analysis showed that whether the basilar artery was completely wrapped was related to the prognosis [hazard ratio=4.596, 95% confidence interval (1.839, 11.488), P=0.001]. ConclusionsPediatric diffuse brain stem gliomas are common in children aged 5-10 years with poor prognosis. Whether the tumor completely surrounds the basilar artery is closely related to the short overall survival time.
