Choroid plexus papilloma (CPP) is a low-grade neoplasm of the choroid plexus that typically occurs in childhood and comprises under 1% of adult brain tumors. In this article, we report our experience delivering craniospinal irradiation (CSI) to a highly unusual case of disseminated CPP in an adult patient 8 years after an initial near total resection. The patient remains free of disease progres...

OBJECTIVE Choroid plexus carcinomas are rare and occur more frequently in children than in adults. The differential diagnosis includes choroid plexus papilloma and papillary ependymoma. The prognosis is generally poor. The objective of this paper is to discuss the epidemiological characteristics, diagnosis, treatment, and prognosis of this rare childhood tumor. CASE REPORT A three-year-old ch...

Pediatric choroid plexus papillomas and carcinomas are highly vascularized neoplasms, which are difficult to distinguish with conventional imaging. We aimed to analyze the diagnostic accuracy of PWI, by using both pseudocontinuous arterial spin-labeling and DSC-PWI. We reviewed the PWI of 13 children with choroid plexus neoplasms (7 papillomas and 6 carcinomas). We quantified CBF, relative CBF,...

Transcerebral removal of a small choroid plexus papilloma in the region of the foramen of Monro was followed within 48 hours by severe and progressive unilateral hydrocephalus. Acute unilateral hydrocephalus is a hitherto unrecognized complication of intraventricular surgery.

Background Choroid plexus carcinomas (CPC) are rare brain tumors with a dismal prognosis. Although the role of surgery has been well established, the question of whether chemotherapy improves the prognosis is still under discussion. Methods We created a database of all cases of choroid plexus tumors (CPT) reported in the literature up to the year 2004 to determine prognostic factors and differe...

Tumors of the choroid plexus (CPT) are rare. While choroid plexus papillomas (CPP) are regarded as benign, choroid plexus carcinomas (CPC) have a dismal prognosis, and there is limited information available regarding the best treatment. Maximal possible surgery is generally believed to be the major prognostic factor, but data to answer the question, of whether second surgery improves the progno...

We report a case of an incidental pineal cyst discovered on MR imaging that progressed to a choroid plexus papilloma. The MR features of pineal cysts, the difficulty of distinguishing benign cysts from cystic neoplasms, and the implications for surgical management are discussed.
