The purpose of this study is to determine whether PTK787/ZK 222584 is effective in treating hemangioblastoma of the brain and/or retina in patients with von Hippel-Lindau disease. The stud...
RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying sunitinib to see how well it works...
Von Hippel-Lindau (VHL) disease is an inherited syndrome manifested by a variety of benign and malignant tumors. Hemangioblastomas are the most common lesion associated with VHL disease a...
Background: - Von Hippel-Lindau (VHL) disease is a rare gene disease. People with VHL often have a brain tumor called hemangioblastoma. Standard treatment for these tumors is risky surger...
This 3-dimensional operative video illustrates resection of a thoracic hemangioblastoma in a 30-year-old female with a history of Von Hippel-Lindau disease. The patient presented with right lower extr...
Optic nerve hemangioblastoma (ONH) is a rare tumor that is usually unilateral and most commonl occurs in the context of von Hippel-Lindau (VHL) disease. Differential diagnosis is based on clinical his...
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 rese...
Hemangioblastoma is composed of neoplastic stromal cells and a prominent capillary network. To date, the identity of stromal cells remains unclear. Mesenchymal stem cells can give rise to committed va...
Spinal hemangioblastomas constitute 1.6-5.8% of all spinal cord tumors. Microsurgical excision of these tumors is challenging. The purpose of this study is to analyze the neurological improvement and ...
Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
An autosomal dominant disorder caused by mutations in a tumor suppressor gene. This syndrome is characterized by abnormal growth of small blood vessels leading to a host of neoplasms. They include HEMANGIOBLASTOMA in the RETINA; CEREBELLUM; and SPINAL CORD; PHEOCHROMOCYTOMA; pancreatic tumors; and renal cell carcinoma (see CARCINOMA, RENAL CELL). Common clinical signs include HYPERTENSION and neurological dysfunctions.
Benign and malignant intra-axial tumors of the MESENCEPHALON; PONS; or MEDULLA OBLONGATA of the BRAIN STEM. Primary and metastatic neoplasms may occur in this location. Clinical features include ATAXIA, cranial neuropathies (see CRANIAL NERVE DISEASES), NAUSEA, hemiparesis (see HEMIPLEGIA), and quadriparesis. Primary brain stem neoplasms are more frequent in children. Histologic subtypes include GLIOMA; HEMANGIOBLASTOMA; GANGLIOGLIOMA; and EPENDYMOMA.
A benign tumor of the nervous system that may occur sporadically or in association with VON HIPPEL-LINDAU DISEASE. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with INTRACRANIAL HYPERTENSION, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)
