HEMANGIOBLASTOMA CEREBRAL PDF
BACKGROUND AND PURPOSE: Cerebellar hemangioblastomas (HBs) are traditionally classified into different morphologic types: cystic and. Hemangioblastomas (capilliary hemangioblastomas) are tumors of the central nervous system that originate from the vascular system usually during middle- age. The occurrence of cerebral hemangioblastoma in a patient with on Hippel-Lindau disease is very rare. In , Rochat described a cerebral hemangioblastoma.

Supratentorial hemangioblastoma is a rare form gemangioblastoma hemangioblastoma; little information is available regarding prognosis, treatment, and clinical characteristics, because the available literature is primarily composed of case reports and small case series.
Therefore, we performed a systematic review of the literature to analyze clinical characteristics, disease progression, and surgical outcomes with respect to survival for supratentorial hemangioblastomas. A total of articles met the search criteria, which combined for a total of patients. On the basis of our analysis of the literature on published cases of supratentorial hemangioblastoma, gross-total resection appears to be superior to other treatment modalities in extending PFS.
Hemangioblastomas are uncommon tumors of the central nervous system CNS that were first described by von Hippel in Supratentorial hemangioblastomas are exceedingly rare. Because of the rarity of hemangioblastomas in this location, the literature is primarily composed of case reports and small series. Little information is available regarding the clinical features of these tumors, particularly in comparison with lesions found in other locations.
No consensus is currently available regarding appropriate management approaches for supratentorial hemangioblastomas or whether supratentorial hemangioblastoma is part hemangioblastooma the stigmata of VHL.
To supplement the current understanding of the clinical significance and management of supratentorial hemangioblastoma, we systematically reviewed the published literature to determine what is known about the presentation and clinical course in patients with this disease.
Where possible, we performed statistical analysis to determine the efficacy of various treatment approaches using the existing body of published patient data. A comprehensive systematic review of the English-language literature hemangiolbastoma performed. A total of articles was identified, of which had patient data regarding supratentorial hemangioblastomas.
All references that contained individual patient data or purely supratentorial aggregated data sets of either histologically confirmed tumors or tumors presenting in the context of confirmed diagnosis of VHL disease were included in our analysis.
Patients with tumors unrelated to hemangioblastoma or VHL disease were excluded from all analyses.
Data from individual and aggregated case series were extracted from each article. The median largest tumor dimension and median tumor volume were not reportable or analyzable in our analysis, hemangiobblastoma studies did not consistently report either value. Patients were considered to have VHL disease if the study reported that they met clinical diagnostic criteria or genetic testing requirements.
Cerebral Hemangioblastoma Occurring in a Patient with von Hippel-Lindau Disease
A clinical diagnosis was made if patients met either of the following 2 criteria: Kaplan-Meier analysis was used to generate time to progression curves. Differences in time to progression were analyzed using the log-rank test. Five percent of patients underwent postsurgical treatment with fractionated radiotherapy.
Follow-up ranged from 0 to months in these studies. All patients receiving fractionated RT as the only treatment modality had presumed hemangioblastoma based on diagnosis of VHL disease. Rate of progression-free survival among patients with gross-total resection GTR and radiation therapy RT of tumors. Because of limitations of the available data on survival, survival analysis provided no significant results for specific treatment modalities. There was a trend toward significance in the association between presence of cysts and PFS; patients with cystic tumors were less likely to present with progression than were those with solid tumors 5-year PFS: When stratified by age, sex, and cystic composition, the association remained significant.
No other significant association was found between tumor location and VHL disease. CNS hemangioblastomas, especially multiple hemangioblastomas, are the most common manifestation of VHL disease.
Our principle goal was to identify features of these tumors that would not be immediately obvious by reading isolated case reports. Of more importance, among 14 tumors with documented serial imaging, 13 tumors showed growth, suggesting that these tumors show high propensity for growth.
Hemangioblastoma is currently considered to be a grade I meningeal neoplasm of uncertain origin according to the latest World Health Organization classification of CNS tumors. Thus, surgery has been the mainstay treatment for CNS hemangioblastomas with good outcomes. In series by Jagannathan et al. Solid tumors seem to have a higher rate of recurrence. Moreover, hemangioblastomas in patients with VHL have high propensity for tumor growth Asymptomatic lesions ceerebral be carefully followed up with a low threshold for surgical resection with development of new symptoms given low risks involved with surgery.
In one study by Jagannathan et al. As a retrospective study, this review is limited by the data available and may reflect source study biases. The diverse range of available data limits hemangioblatoma number of variables that can be analyzed and controlled.
Variables of possible interest, such as tumor volume and histological variants, were reported inconsistently and could not be analyzed. In conclusion, we report patient, tumor, and treatment characteristics for previously published cases of supratentorial hemangioblastomas.
Because of the relative rarity of this tumor, this study aims to accurately describe outcome and tumor location characteristics using a data set that would be difficult to accumulate at a single center treating this tumor.
