A Choroid plexus papilloma (CPP) is a rare, slow-growing, histologically benign intracranial neoplasm or tumor that is commonly located in the ventricular system of the choroid plexus. It leads to increased cerebrospinal fluid production, thus causing increased intracranial pressure and hydrocephalus.
Frequency and age affected
Internationally tumors of the choroid plexus are rare, accounting for 0.4-0.6% of all intracranial neoplasms. It most commonly affects young children under the age of 5 with a mean patient age of 5.2 years.
Signs and symptoms
Signs of the tumor resulting from increased intracranial pressure are present in 91% of patients, with vomiting, homonymous visual field defects and headache being the most common symptoms. Other symptoms are ear ringing and dizzyness.
Choroid plexus papillomas are benign tumors that are usually cured by surgery; malignant progression has been rarely reported.
