Choroid plexus tumor

Choroid Plexus Tumor

A Choroid Plexus Tumor is a rare type of brain tumor that originates in the choroid plexus, a network of cells that produce the cerebrospinal fluid (CSF) that cushions and protects the brain and spinal cord. These tumors can occur at any age but are most commonly diagnosed in children, particularly those under the age of 2.

Types of Choroid Plexus Tumors

There are three main types of choroid plexus tumors:

• Choroid Plexus Papilloma (CPP): This is the most common type and is usually benign (non-cancerous). It grows slowly and does not spread to other parts of the brain.

• Atypical Choroid Plexus Papilloma (aCPP): This type is also benign but grows more aggressively than CPP and has a higher chance of recurring after treatment.

• Choroid Plexus Carcinoma (CPC): This is a malignant (cancerous) tumor that grows rapidly and can spread to other parts of the brain and spinal cord.

Symptoms

The symptoms of a choroid plexus tumor depend on its size and location but can include headache, nausea, vomiting, seizures, and problems with balance or coordination. In infants, symptoms may also include a rapidly increasing head size due to the accumulation of excess CSF, a condition known as hydrocephalus.

Diagnosis

Diagnosis of a choroid plexus tumor typically involves a neurological examination, imaging tests such as MRI or CT scan, and a biopsy to determine the type and grade of the tumor.

Treatment

Treatment for a choroid plexus tumor usually involves surgery to remove as much of the tumor as possible. This may be followed by radiation therapy or chemotherapy, particularly for malignant tumors or those that could not be completely removed. In some cases, a shunt may be placed to drain excess CSF and relieve symptoms of hydrocephalus.

Prognosis

The prognosis for a choroid plexus tumor depends on several factors, including the type and grade of the tumor, the extent of the tumor at the time of diagnosis, the patient's age and overall health, and the success of treatment.
