OBJECTIVE Extraventricular intraparenchymal choroid plexus tumors (CPTs) in the cerebral hemisphere are extremely rare. The aim of this study was to investigate the clinical characteristics, radiologic findings, and surgical outcomes of this atypical type of CPT. METHODS The study comprised 6 patients with pathologically proven extraventricular intraparenchymal CPTs who were surgically treate...

A case is presented of a patient with dysphonia, hearing loss and ataxia due to vestibulocochlear and vagal nerve compression by choroid plexus papilloma in the cerebellopontine angle. Choroid plexus papillomas are rare tumors usually arising in the lateral and fourth ventricle, and rarely found in the cerebellopontine angle, making the neuroimaging characteristics usually not sufficient for di...

Abstract Background Choroid plexus papillomas (CPPs) are histopathologically benign and rare central nervous system tumors. These tumors remain more frequent in children than adults. It is infrequent for these to cause a sudden unexpected death. We aim this case discuss the unusual fatal presentation of choroid papilloma mechanism Case we report 61-year-old man with no medical history, diagnose...

At 8-22 weeks gestation, the lateral ventricular choroid plexus swells with glycogen deposits, which are thought to be an important source of anaerobic energy for a relatively hypovascular stage of brain development. Sonographic images during this phase demonstrate enlarged and echogenic ventricles, accounting for up to 80%-90% of the cerebral axial dimension in the earliest gestations studied....
