We reported a rare case of choroid plexus papilloma arising at the foramen of Luschka of the fourth ventricle. The features of the tumor, as observed by computed tomography, magnetic resonance imaging and digital subtraction angiography are described, along with a review of the literature.

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....

Choroid plexus papilloma (CPP) is a rare benign tumor of the central nervous system with a propensity for location within the lateral ventricle in children. We report a case of a 14-year-old girl who presented with transient facial paresis and ataxia. Her imaging showed a non-enhancing intra fourth ventricular mass, the histology of which was reported as CPP. The atypical clinical and radiologi...

Choroid plexus carcinoma is a rare intracranial neoplasm, affecting mainly very young children. The commonest site is within the lateral ventricles and the prognosis is very poor. We report a seven month old baby boy who presented with raised intracranial pressure and seizures. Brain CT scan showed large intraventricular mass with calcification and hydrocephalus. Total macroscopic resection of ...
