Choroid plexus papillomas are rare, benign tumors that originate in the choroid plexus, which is a structure in the brain responsible for producing cerebrospinal fluid. This type of tumor mainly affects children and can occur in various parts of the brain, with the lateral ventricles being the most common location.
Choroid plexus papillomas are characterized by the formation of small, finger-like projections called papillae, which can obstruct the flow of cerebrospinal fluid within the ventricles, leading to an increase in intracranial pressure. Symptoms may include headaches, vomiting, seizures, changes in vision, and developmental delays in infants. However, sometimes these tumors are found incidentally during a brain imaging scan, even in the absence of symptoms.
The exact cause of choroid plexus papillomas is unknown, but they are believed to arise from an abnormal growth of cells in the choroid plexus. These tumors are typically slow-growing and non-aggressive, but in rare cases, they may become malignant and spread to other parts of the brain or spinal cord.
Treatment for choroid plexus papillomas usually involves surgical removal of the tumor to relieve symptoms and prevent complications. The prognosis is generally favorable, with a low likelihood of recurrence if the entire tumor is successfully removed. Regular follow-up appointments and imaging scans are recommended to monitor for any potential regrowth or metastasis.
