Choroid plexus papilloma

Abstract

Choroid plexus tumors are rare intracranial tumors which account for only 0.4-0.6% of all brain tumors. These are intraventricular papillary neoplasms derived from choroid plexus epithelium and range from choroid plexus papillomas (World Health Organisation (WHO) grade I) to choroid plexus carcinomas (WHO grade III). It is an important albeit rare cause of hydrocephalous. We present to you the case of a 1-year-old child who presented with the signs and symptoms of hydrocephalous and was diagnosed as choroid plexus papilloma on histopathology.

A Case of Choroid Plexus Papilloma with Rare Location Presenting with Impaired Consciousness

“…Bilateral lateral ventricular diameters were larger than normal in CT scan of our patient. The lesion shows Ünal et al Choroid Plexus Papillom homogeneous isointensity on T1-weighted images and hyperintensity on T2-weighted images in MRI, as in our patient (5).…”

“…The factors associated with prognosis in CPP are symptoms, the size and the location of the tumor (5). In CPP, 1,5-year survival rates were reported as 90%, 81% and 71%, respectively (7).…”

Extracerebral choroid plexus papilloma in the pharynx with airway obstruction in a newborn: a case report

“…The expression of p53 is to be also diagnosed as choroid plexus carcinoma but undetected in the CPPs [15]. Positive of cytokeratin, S-100 and vimentin are well documented in CPP, and the absence of Epithelial Membrane Antigen (EMA) and GFAP further favors the diagnosis of CPP [16]. In this case, there is typical WHO grade I CPP, and no anaplastic features identified.…”

“…[8] Fifty percent of all CPPs originate from the lateral ventricle, 40% from the fourth ventricle, and 5% are either found in the third ventricle or in multiple ventricles. [8,11] Symptomatology differs according to tumor location: third ventricle CPPs were described with seizures, vision disturbances, and hemiparesis, while fourth ventricle CPPs were associated with headache, ataxia, vomitus, and visual symptoms. [11] CPPs occur only rarely outside of the ventricles with a few case reports describing CPPs at the cerebellopontine angle, the suprasellar region, and the posterior fossa.…”

[13] Here, we report a case of a recurrent CPP that originated from the fourth ventricle, while years later, it reoccurred in the left middle cerebellar peduncle (MCP).…”
