angiofibromas are the most common benign tumors of the nasopharynx, intracranial extension has been reported in approximately 20-25% of cases. intracranial extension may be difficult to treat because of poor exposure that may lead to recurrence. a 16-year-old male patient presented with a 6-month history of nasal obstruction, intermittent epistaxis, right superior orbital fissure syndrome, and ...

Background: Metastasis of systemic neoplasms to the spine is common; however, metastasis primary spinal cord tumors other regions in body an infrequent occurrence. A few case reports have described tumors, and most cases, patients were younger than 30 years age. Case Description: We present illustrative a 47-year-old female with metastatic lesions lumbosacral vertebrae after initial diagnosis i...

OBJECTIVE T-stage is an imperfect prognostic indicator for patients with nasopharyngeal carcinoma. We evaluated the effect of extent of intracranial involvement on survival after conventional radiotherapy in patients with Stage T4 nasopharyngeal carcinoma. METHODS We conducted a retrospective analysis of the results of computed tomography, magnetic resonance imaging and treatment outcomes in ...

Efforts to produce intracranial neoplasia by various chemical carcinogens have been attended with scant success prior to the work of Seligman and Shear (2). By intracerebral implantation of pellets of 2o-methylcholanthrene, these workers produced i i gliomas and 2 fibrosarcomas in a series of 2o male mice of the C3H strain. Seligman and Shear reported also successful subcutaneous transplantatio...

Gliomas are the most common primary intracranial tumors. One extracellular matrix component that has been implicated in glial tumor biology is brain enriched hyaluronan binding (BEHAB)/brevican. In this study, the CNS-1 rat glioma cell line was transfected with a vector containing either a full-length BEHAB/brevican cDNA, a 5' insert encoding the NH(2)-terminal BEHAB/brevican cleavage product, ...

Received, November 20, 2004. Accepted, May 19, 2006. TO REVIEW THE literature on endovascular therapies available to clinicians to aid in the management of head, neck, and intracranial tumors. Hypervascular tumors of the head and neck region, as well as the intracranial region, are associated with large amounts of blood loss intraoperatively. Preoperative embolization of selected hypervascular ...

Combined chemotherapy and prophylactic cranial irradiation has improved the prognosis of children with acute leukemia. However cranial irradiation carries a latent risk of the induction of secondary intracranial tumors. We encountered a patient who developed multiple intracranial radiation-induced meningiomas (RIMs) 25 years after prophylactic cranial irradiation for the treatment of acute leuk...

Intracranial lipomas (iLp) are very rare congenital malformative lesions, being less than 0.1% of intracranial tumors [1]. They originate from abnormal differentiation of the mesenchimal tissue of meninx primitiva [2–4]. Intracranial lipomas mainly localize in the pericallosal zone, where they are mostly asymptomatic, being frequently associated to other defects of differentiation of the midlin...
