Spontaneous Arrest of Sporadic Spinal Hemangioblastoma Growth after Postoperative Nodular Recurrence: Case Report.

Cureus 2018 Sep 28;10(9):e3380. Epub 2018 Sep 28.

Neurosurgery, The Icahn School of Medicine at Mount Sinai, New York, USA.

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

Repurposing propranolol as an antitumor agent in von Hippel-Lindau disease.

Authors:

J Neurosurg 2018 Oct 1:1-9. Epub 2018 Oct 1.

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

Risk of radiation-associated intracranial malignancy after stereotactic radiosurgery: a retrospective, multicentre, cohort study.

Lancet Oncol 2018 Nov 22. Epub 2018 Nov 22.

Department of Neurosurgery, Laura and Isaac Perlmutter Cancer Center, NYU Langone Health System, New York University, New York, NY, USA. Electronic address:

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]).

Retromedullary Hemangioblastoma Mimicking a PICA Aneurysm: Case Report & Literature Review.

World Neurosurg 2018 Nov 4. Epub 2018 Nov 4.

Texas A&M College of Medicine, Temple, Texas, USA; Department of Neurosurgery, Baylor Scott & White Health, Temple, Texas, USA. Electronic address:

Background: Hemangioblastomas (HBMs) are benign vascular neoplasms that most commonly arise within the cerebellum. While other vascular lesions should be considered in the differential diagnosis, HBMs rarely resemble aneurysms on neuroimaging and only one case of a cerebellar HBM mimicking a posterior fossa aneurysm has been reported. Here we describe a retromedullary HBM that masqueraded as a distal posterior inferior cerebellar artery (PICA) medullary branch aneurysm. Read More

Hemangioblastoma of the optic nerve.

Surv Ophthalmol 2018 Oct 13. Epub 2018 Oct 13.

Sheffield Ocular Oncology Service, Royal Hallamshire Hospital, Sheffield, UK.

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.

Division of Endocrinology and Metabolism, Department of Medicine, University of Rochester School of Medicine and Dentistry, Rochester, New York 14642, USA.

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-Lindau disease (vHL, familial cerebello-retinal angiomatosis) is a rare genetic autosomal dominant disorder associated with predisposition to vascular tumors. Mutations of VHL tumor suppressor gene, located on chromosome 3p25-26, are responsible for clinical manifestation of the disease. The VHL gene product encodes VHL protein, which is responsible for HIF-1 (hypoxia-inducible factor-1) dependent cell cycle regulation and cellular pathways mediated by VEGF, PDGF, TGF-α, EPO.

OBJECTIVE Akin to the nonoperative management of benign intracranial tumors, stereotactic body radiation therapy (SBRT) has emerged as a nonoperative treatment option for noninfiltrative primary spine tumors such as meningioma and schwannoma. The majority of initial series used higher doses of 16-24 Gy in 1-3 fractions. The authors hypothesized that lower doses (such as 12-13 Gy in 1 fraction) might provide an efficacy similar to that found with the dose de-escalation commonly used for intracranial radiosurgery to treat acoustic neuroma or meningioma and with a lower risk of toxicity.

We report the case of a 21-year old woman presenting with high blood pressure and raised normetanephrine levels. Indium-111-pentetreotide single photon-emission computed tomography with computed tomography (SPECT/CT) and 2-deoxy-2-[fluorine-18]fluoro-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT) imaging showing isolated tracer-uptake by a 2 cm tumor close to the costovertebral angle of the third thoracic vertebra. Thoracic surgery led to normalization of normetanephrine levels. Read More

A Method for Cranial Nerve XI Silencing During Surgery of the Foramen Magnum Region: Technical Case Report.

Oper Neurosurg (Hagerstown) 2018 May 18. Epub 2018 May 18.

Department of Neurological Surgery, University of California, San Francisco, California.

Background And Importance: Skull base surgery involves the microdissection and intraoperative monitoring of cranial nerves, including cranial nerve XI (CN XI). Manipulation of CN XI can evoke brisk trapezius contraction, which in turn may disturb the surgical procedure and risk patient safety. Here we describe a method for temporarily silencing CN XI via direct intraoperative application of 1% lidocaine. Read More

Microsurgical Resection of Spinal Cord Hemangioblastoma: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2018 Dec;15(6):E88-E89

Semmes Murphey Neurologic & Spine Institute, Memphis, Tennessee.

This video demonstrates microsurgical resection of spinal cord hemangioblastoma. Hemangioblastomas are rare, benign, highly vascularized tumors classified as grade I according to World Health Organization classification systems. About 3% of all intramedullary tumors are hemangioblastomas. Read More
