Cerebral angiofibroma: case report

Rare Infratentorial and Supratentorial Localization of Juvenile Angiofibroma: A Case Report

Angiofibromas are rare tumors of the head and neck that mostly occur in the sphenopalatine region. We present a case of angiofibroma in a young male patient with an unusual and extremely rare localization, which to our knowledge has not been described before. It was situated in the tentorium and spread to the supratentorial and infratentorial regions. The patient initially presented with symptoms of increased intracranial pressure. After a diagnostic evaluation was done, the whole tumor was successfully removed using the supratentorial and infratentorial approach and the microsurgical technique.

Angiomyxofibromatous Tumor of the Falx Cerebri

We report a distinctive angiomyxofibromatous lesion arising from the falx cerebri of a 48-year-old woman. The tumor was composed of bland-appearing, spindle, and stellate cells in a myxoid matrix with prominent vascularity. The tumor cells were immunopositive diffusely for vimentin and focally for S-100 protein, but were immunonegative for epithelial membrane antigen, CD34, MIC2, Bcl-2, glial fibrillary acidic protein, cytokeratin CAM 5.2, desmin, and smooth muscle actin. This lesion could not be categorized according to the current World Health Organization classification of tumors of the nervous system, thus underscoring a need to enhance our understanding of myxoid mesenchymal neoplasms and reassess their nosology.
