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 [1 ] cerebrospinal fluid production, thus causing increased intracranial pressure and hydrocephalus. [2 ]
Pathophysiology [ edit ]
The tumor is neuroectodermal in origin and similar in structure to a normal
choroid plexus. They may be created by epithelial cells of the choroid plexus.
Frequency and age affected [ edit ]
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 [ edit ]
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.
Surgical treatment [ edit ]
Choroid plexus papillomas are benign tumors that are usually cured by surgery; malignant progression has been rarely reported.
