Prognostic implications of atypical histologic features in choroid plexus papilloma.
The prognostic significance of atypical histologic features in choroid plexus tumors remains uncertain. Therefore, a series of 164 choroid plexus tumors was evaluated for the presence of atypical histologic features, including mitotic activity, increased cellularity, nuclear pleomorphism, blurring of papillary growth pattern, and necrosis. The impact of histopathologic and clinical features on ...
متن کاملSurgical Removal of a Huge Atypical Choroid Plexus Papilloma
The authors present a case of huge atypical choroid plexus papilloma in both lateral and third ventricles. A 2-yearold girl presented with lethargy and vomiting. Magnetic resonance images disclosed a huge enhancing mass, which probably arose from the left lateral ventricle and extended to the right lateral and the third ventricles. Total removal of the mass via the interhemispheric transcallosa...
متن کاملAtypical Choroid Plexus Papilloma Treated With Single Agent Bevacizumab
Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages. Papillomas have an indolent course and carry a good long-term outcome if gross total surgical resection is achieved. However malignant evolution may occur, with a 10-30% incidence....
متن کاملMalignant progression in choroid plexus papillomas.
OBJECT Malignant progression of choroid plexus papillomas has been occasionally reported, but this issue has not yet been systematically addressed. METHODS Frequency and extent of malignant progression were examined in a retrospective series of 124 primary choroid plexus papillomas using uniform histological criteria. RESULTS After gross-total resection and a mean follow-up period of 59 mon...

choroid plexus papillomas are rare intracranial tumors, accounting for less than 1% of all intracranial tumors in adults. however, they are relatively more common in children and constitute 1.5 to 4% of childhood intracranial tumors. in children, choroid plexus papillomas are predominately located in the lateral ventricles, followed by the forth and third ventricles and, rarely, in the cerebell...
