Hemangioblastomas are rare benign, highly vascularized tumors occurring in the cerebellum and the spinal cord. They often develop tumor-associated cysts multiple times the size of the solid part of the tumor. Patients with von Hippel-Lindau (VHL) disease typically exhibit multiple tumors with the need of repeated surgeries during their lifetime. Read More

Purpose: This is the first single-institution study of its size to characterize the treatment impact and to address the question of whether hemangioblastoma treatment with Gamma Knife Stereotactic Radiosurgery (GKRS) in both sporadic and VHL patients changes the characteristic saltatory hemangioblastoma growth pattern.

Methods: The authors reviewed a single-institution tumor registry to identify patients who had received GKRS for hemangioblastomas between January 1st, 1999, and December 31st, 2017.

Results: 15 patients with 101 lesions met search criteria with a median age of first GKRS of 39. Read More

Vascular disorders of the spine are more rare than cerebral vascular entities but can result in significant morbidity. These lesions frequently demonstrate distinguishing characteristics by imaging that are imperative for the radiologist to recognize to properly guide diagnosis and treatment. We review distinguishing imaging characteristics for spinal vascular malformations, spinal emergencies, and spinal vascular masses. Read More

Purpose: Haemangioblastomas (HABLs) and pilocytic astrocytomas (PAs) are brain tumours presenting similar appearance and location in conventional magnetic resonance (MR) imaging. The purpose of our study was to determine whether a detailed analysis of diffusion (DWI) and perfusion (PWI) characteristics can be useful in preoperative differentiation of these tumours.

Material And Methods: The study group consisted of biopsy proven six HABLs and six PAs, which underwent preoperative standard MR examinations including PWI and DWI. Read More

Hemangioblastomas represent 3% of all central nervous system (CNS) tumors. The majority of CNS hemangioblastomas are infratentorial, with the cerebellum being the most frequent location, while 13% are found in the brainstem. Symptoms of brainstem hemangioblastomas can be very subtle and might therefore be overlooked or misinterpreted. Read More

Hemangioblastomas are rare, slow-growing, highly vascularized tumors of the central nervous system which often occur in the spinal cord. When presenting as sporadic, isolated tumors without Von-Hippel Lindau disease, they are curable through surgery with a low rate of recurrence. Tumor recurrence in these cases is usually associated with prior subtotal resection. Read More

OBJECTIVEVon Hippel-Lindau disease (VHL) is a tumor predisposition syndrome characterized by CNS hemangioblastomas (HBs) and clear cell renal cell carcinomas (RCCs) due to hypoxia-inducible factor activation (pseudohypoxia). Because of the lack of effective medical therapies for VHL, HBs and RCCs account for significant morbidity and mortality, ultimately necessitating numerous neurological and renal surgeries. Propranolol is an FDA-approved pan-beta adrenergic antagonist with antitumor effects against infantile hemangiomas (IHs) and possibly VHL HBs. Read More

Background: A major concern of patients who have stereotactic radiosurgery is the long-term risk of having a secondary intracranial malignancy or, in the case of patients with benign tumours treated with the technique, the risk of malignant transformation. The incidence of stereotactic radiosurgery-associated intracranial malignancy remains unknown; therefore, our aim was to estimate it in a population-based study to assess the long-term safety of this technique.

Methods: We did a population-based, multicentre, cohort study at five international radiosurgery centres (Na Homolce Hospital, Prague, Czech Republic [n=2655 patients]; Ruber International Hospital, Madrid, Spain [n=1080], University of Pittsburgh Medical Center, Pittsburgh, PA, USA [n=1027]; University of Virginia, Charlottesville, VA, USA [n=80]; and NYU Langone Health System, New York, NY, USA [n=63]).

Optic nerve hemangioblastoma is a rare tumor that is usually unilateral and most commonly occurs in the context of von Hippel-Lindau disease. Differential diagnosis is based on clinical history and imaging. Magnetic resonance imaging with gadolinium enhancement is the most useful imaging modality as it can reveal flow voids and an absence of dural attachment, differentiating optic nerve hemangioblastoma from other more commonly encountered optic nerve tumors.

Von Hippel-Lindau (VHL) disease, caused by germline mutations in the gene, is characterized by metachronously occurring tumors including pheochromocytoma, renal cell carcinoma (RCC), and hemangioblastoma. Although VHL disease leads to reduced life expectancy, its diagnosis is often missed and tumor screening guidelines are sparse. VHL protein acts as a tumor suppressor by targeting hypoxia-inducible factors (HIFs) for degradation through an oxygen-dependent mechanism. Read More

Hemangioblastomas are benign tumors of the central nervous system (CNS) that may occur either sporadically or as part of von Hippel-Lindau (VHL) disease, in which they coexist with a series of other tumors outside the CNS. Because of their low mitosis rate, hemangioblastomas usually have slow-growing and late manifestations, but may cause sudden neurological symptoms if tumor hemorrhage occurs. Few studies have evaluated the impact of pregnancy on the evolution of hemangioblastomas. Read More

Von Hippel-Landau (VHL) disease is characterized by malignant and benign tumors in multiple organs. Sunitinib, a tyrosine kinase inhibitor, has been clinically available for treating sporadic patients with recurrent or unresectable and metastatic clear renal cell carcinomas (cRCCs) and metastatic lesions of the lung, but its effect on VHL disease-associated tumors remains poorly understood. This retrospective case series examined the effect of sunitinib on RCC, hemangioblastomas, pheochromocytomas, and pancreatic neuroendocrine tumors in patients with confirmed VHL. Read More
