Abstract
Hemangioblastoma (HBM) is a tumor distinguished by the presence of stromal cells and small vessels. These stromal cells represent stem cells, which, due to the influence of the neoplasm, proliferate and differentiate into "vasoformative elements" that create new blood vessels. Hemangioblastomas resemble arteriovenous malformation (AVM) in imaging features, characterized by an apparent vascular blush, the presence of multiple feeding vessels, and evident draining veins observed on digital subtraction angiography (DSA). Our study presents a case of HBM in the right cerebellar hemisphere mimicking AVM. The patient had been diagnosed with AVM in the same location two years ago and managed with endovascular embolization. One month prior, the patient experienced severe headaches, imbalance, nausea, left ear fullness, blurry vision, and high blood pressure. The imaging feature suggests HBM rather than AVM. The patient next underwent sub-occipital craniotomy and tumor resection with external ventricular drainage (EVD) insertion. The histopathological report of the excised mass confirmed HBM. In conclusion, AVM and HBM rarely occur together. Recent research indicates that HBM and AVM have exact embryologic origins and need later genetic alterations to develop into symptomatic lesions. Further research is required to clarify the uncommon combination of these lesions.

Case Report of a Hemangioblastoma With Large Blood Vessels and Rare Vascular Anomalies: Is It Fibromuscular Dysplasia or Arteriovenous Malformation Association? Cureus 2022; 14:e24527. [PMID: 35651437 PMCID: PMC9138196 DOI: 10.7759/cureus.24527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/27/2022] [Indexed: 12/03/2022] Open
Abstract
Hemangioblastoma is considered a benign neoplasm characterized by abnormal vasculature and stromal cells; several pathophysiological mechanisms have been proposed, such as genetic predisposition, hormonal factors, and arterial wall ischemia. Fibromuscular dysplasia is characterized by hyperplasia or thinning of the smooth muscle, elastic fibre destruction, fibrous tissue proliferation, and arterial wall disorganization. We present a cerebellar hemangioblastoma case not associated with Von Hippel Lindau syndrome. Histologically we evidenced big vessels with anomalies of the vascular walls corresponding to fibromuscular dysplasia, and those changes have not been described in these types of tumors. In this light, rare findings could be called vascular malformations or degenerative vascular changes, fibromuscular dysplasia or vascular anomalies. Arterio-venous malformation and hemangioblastoma pathology are rarely presented together. Notwithstanding, we could say that it is a stromal stem cell tumor in a varied stage of differentiation.

Advanced magnetic resonance imaging findings of cerebellar hemangioblastomas: A report of three cases and a literature review. Acta Radiol Open 2022; 11:20584601221077074. [PMID: 35273810 PMCID: PMC8902200 DOI: 10.1177/20584601221077074] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 01/12/2022] [Indexed: 11/17/2022] Open
Abstract
On conventional magnetic resonance imaging (MRI), hemangioblastomas typically
appear as mural nodules with an adjacent surrounding cyst or a solid mass in the
cerebellum. However, hemangioblastomas sometimes cannot be reliably
distinguished using this imaging technique from other tumors, especially
pilocytic astrocytomas and metastatic tumors, because of their similar imaging
findings and locations. Herein, we report three cases of cerebellar
hemangioblastomas and review their findings on conventional and advanced MRI,
including diffusion-weighted imaging (DWI), dynamic susceptibility-weighted
contrast-enhanced perfusion-weighted imaging (DSC-PWI), and magnetic resonance
spectroscopy (MRS). Solid contrast-enhanced lesions of hemangioblastomas showed
increased apparent diffusion coefficient values on DWI, increased relative
cerebral blood volume ratio on DSC-PWI, and high lipid/lactate peak on MRS.
Therefore, advanced MRI techniques can be helpful in understanding the
pathological and metabolic changes of hemangioblastomas and may be useful for
their characterization.

Abstract
RATIONALE Hemangioblastomas (HGBMs) are very rare, and the cerebellum is usually the most common site of occurrence. HGBMs with ring-enhanced walls are often misdiagnosed as metastases, abscesses, glioblastomas, tuberculomas, and demyelinating diseases. Thus, we present a rare case of HGBM masquerading as a ring-enhancing lesion in the cerebellum. PATIENT CONCERNS We present a 33-year-old female who was admitted to our department because of headaches, unstable walking, and visual loss in both eyes. Cranial nerve examination revealed deficits in cranial nerve II. DIAGNOSIS Magnetic resonance imaging revealed 2 cystic lesions in the cerebellum, with irregular ring-enhanced cyst walls composed of smaller nodular parts. Immunohistochemical staining of resected specimens established HGBM. INTERVENTIONS The lesions were completely resected using a right retrosigmoid approach. OUTCOMES Two years of follow-up revealed no recurrence of her symptoms or tumor. She is currently well and performs her daily duties. LESSONS HGBMs with enhanced cysts are often misdiagnosed by radiology because of their ring-enhanced nature. Computed tomography angiography may be the best modality for differentiating cerebellar HGBM from other ring-enhancing lesions. Surgery is the gold standard of treatment for these lesions.

Abstract
OBJECTIVE The purpose of this paper is to describe the variation of surgical plan and technique required in a rare subset of hemangioblastomas compared with the accepted general strategy. The established rule in hemangioblastoma surgery is to avoid cyst wall removal, as it is not neoplastic, and it will not recur if mural nodule is completely removed. However, the wall of the associated cyst is occasionally enhanced by gadolinium on preoperative magnetic resonance imaging. METHODS We present the case of a patient with a hemangioblastoma that was progressively compressed by a growing cyst, with the final appearance of a contrast-enhanced cyst wall. We collected similar cases reported in the literature. RESULTS Our study points out the need for a tailored preoperative strategy, the usefulness of intraoperative fluorescent dyes, and the crucial role of frozen section histopathologic analysis to confirm diagnosis and optimize treatment. CONCLUSIONS When a hemangioblastoma is associated with a contrast-enhanced cyst, care must be taken to intraoperatively confirm the presence of neoplastic cells and eventually remove the neoplastic cyst wall to reduce the risk of recurrence.

Abstract
BACKGROUND Solid/cystic hemangioblastomas are rare, and they lack a systematic description. We clarify the epidemiology, clinical features, imaging characteristics, and surgical outcomes of sporadic solid/cystic hemangioblastomas in the cerebellum. METHODS A total of 75 patients with sporadic hemangioblastomas from 2006 to 2018 were enrolled in this retrospective study and divided into solid (26/75), cystic (40/75), and solid/cystic (9/75) groups according to the imaging findings. All patients underwent microsurgical resection and had a definite 31 pathologic diagnosis. RESULTS The age at diagnosis in the solid/cystic group was the highest among the 3 groups (P < 0.05). The solid/cystic group showed the shortest symptom duration (P < 0.05), which was related to obvious peritumoral brain edema (P < 0.05). The combination of computed tomography angiography and magnetic resonance imaging helped with the differential diagnosis. The solid/cystic group showed the lowest rate of gross total resection (P < 0.05) as a result of the obscure brain-tumor interface, and the guidance of intraoperative ultrasonography helped with the microsurgical procedures to a certain extent. Patients in the solid/cystic group showed greater intraoperative blood loss (P < 0.05), a lower ratio of symptom improvement (P < 0.05), and a longer mean hospital stay (P < 0.05) than did patients in the cystic group. CONCLUSIONS Cerebellar sporadic solid/cystic hemangioblastomas are rare and usually affect elderly people. The combination of computed tomography angiography and magnetic resonance imaging may improve the preoperative diagnosis. Solid/cystic hemangioblastomas showed the lowest rate of gross total resection as a result of the obscure brain-tumor interface.

Abstract
BACKGROUND Posterior cranial fossa (PCF) hemangioblastomas are benign, highly vascularized, and well-differentiated tumors with well-described histopathologic features. Although relatively rare, this tumor is the most prevalent primary tumor of the cerebellum in adults. OBJECTIVE Because the demographics of patients with such a tumor (as well as the clinical, morphologic, pathologic, surgical features, and outcomes) are not fully understood, we systematized characteristic patient and tumor features. METHODS We undertook a systematic review of the English-language literature in PubMed for PCF hemangioblastomas in adults published in the past 31 years. We analyzed geographic distribution and year of publication of articles; demographic data of patients; presenting symptoms and clinical signs; tumor location and morphology; histopathologic features, extent of tumor resection, perioperative blood loss, and postoperative complications; length of hospital stay; and outcomes. RESULTS We reviewed 207 articles describing 1759 infratentorial hemangioblastomas in a cohort of 1515 adult patients. We found female predominance in patients with Von Hippel-Lindau disease (VHLD) compared with male predominance in the general patient group. Symptoms of intracranial hypertension were more common in the VHLD group compared with the general group of patients. The cerebellar location was more common in the VHLD group and solid (parenchymatous) tumor was the most common type. Most patients underwent total resection but rate of resection did not differ between the general and VHLD groups. Most patients had a favorable outcome. CONCLUSIONS The literature of adult PCF hemangioblastomas is limited and general surgical experience with such tumors is scarce because of their rarity. Rates of postoperative complications and mortality remain higher than expected. However, prognosis and surgical outcomes are generally favorable. Nevertheless, surgery of adult PCF hemangioblastomas is a demanding and challenging task.

Abstract
BACKGROUND Posterior fossa hemangioblastomas are WHO grade I benign lesions with a surprisingly high recurrence rate. This study determines the factors responsible for recurrence and the clinico-radiological and histopathological differences between primary (group A; n = 60) and recurrent/symptomatic residual (group B; n = 24) tumors. METHODS Radiologically, tumors were differentiated into cystic, cystic with a mural nodule, solid-cystic/microcystic and solid. Surgery was undertaken via a midline or lateral suboccipital approach. Histopathology differentiated them into reticular, cellular or mixed subtypes. RESULTS Truncal-appendicular ataxia in group A and von Hippel-Lindau (VHL) disease and raised intracranial pressure in group B were the predominant presentations. VHL patients in group B had a longer duration of symptoms (median 72 months) than those with non-VHL recurrences (median: 36 months). Multicentric mural nodules (n = 9/24, 37.50%, P = 0.0001) and bilateral cerebellar hemispheric involvement (n = 6/24, 25%, P = 0.0003) were exclusively seen in the preoperative radiology of group B tumors. Brainstem involvement was seen in the tumors of ten (16.67%) patients in group A and six (25.00%) patients in group B. One subset of patients required several resurgeries for repeated recurrences. Abnormal vascular proliferation and papillary projections into adjacent brain, and highly cellular stroma were unique histological features at recurrence. Total resection was achieved in 45 group A and 19 group B patients. The outcome based on the Karnofsky performance scale (KPS) was assessed at follow-up at 6 weeks (A: n = 60, B: n = 24): KPS0: A = 4, B = 1; KPS10-40 (dependent): A: 4, B = 5; KPS50-70 (independent for daily needs): A = 36, B = 16; KPS80-100 (fully independent): A = 16; B = 2. CONCLUSIONS In recurrent/residual tumors, the radiological as well as histopathological features showed a distinctive change toward a more aggressive nature. Higher incidences of multiple mural nodules, bilateral spread, remote recurrence and VHL disease at preoperative radiology; as well as proliferative angioarchitecture, an irregular brain tumor interface and highly cellular stroma at histology were found in these patients compared to their primary counterparts.

Abstract
BACKGROUND Hemangioblastomas (HBL) are uncommon tumors of the central nervous system (CNS), corresponding to 1-2.5% of all intracranial tumors. They can present sporadically or in patients with von Hippel-Lindau (VHL) disease and are most often located in the cerebellum, brainstem, and spinal cord. VHL disease is a multiple neoplasia syndrome inherited in an autosomal dominant fashion and caused by a VHL suppressor gene deletion. We present our experience in the management of patients with cerebellar HBL. METHODS Thirty consecutive patients with cerebellar HBL were included in this study. Hospital charts, radiological images, and operative records were reviewed. Modified Rankin scores were used to evaluate the clinical course. RESULTS Thirty patients diagnosed with cerebellar HBL were operated. Complete total resection was achieved in 93% of the cases. Postoperatively, 83% of the patients showed good functional recovery. CONCLUSIONS HBL of the cerebellum should be resected when symptomatic or when the tumor (or a tumor-associated cyst) shows signs of enlargement. Surgical intent should seek en bloc resection to minimize intraoperative bleeding. Patients with HBLs must be tested for VHL gene mutations, and in confirmed cases, relatives should be offered genetic counseling.

Abstract
A 30-year-old woman suffered cerebellar hemorrhage during the delivery of her first child. She had undergone surgical removal of a symptomatic cerebellar hemangioblastoma 6 years previously. Neuroradiological examinations indicated recurrent hemangioblastoma, confirmed by histological examination of the surgical specimen. She was discharged with no neurological deficit. Hemangioblastomas are benign tumors that are curable with surgical removal, but can grow during pregnancy. Women of reproductive age who have been treated for hemangioblastoma need careful long-term follow up, even if they show no signs of lesion recurrence.
