Understanding Central Neurocytoma of Brain (ICD-11 Code 2A00.3)

Central neurocytoma of brain, identified by the ICD-11 code 2A00.3, is a very rare, low-grade, primary neuronal tumour affecting the central nervous system. Typically classified as a World Health Organization (WHO) grade II tumour, it most commonly develops within the lateral ventricles of the brain, though it can occasionally be found in the third ventricle. Its slow-growing nature and intraventricular location are characteristic features.

Symptoms and Presentation of Central Neurocytoma

Patients with central neurocytoma often present with symptoms indicative of increased intracranial pressure. This is frequently due to the tumour obstructing the flow of cerebrospinal fluid, leading to hydrocephalus (a build-up of fluid in the brain). Common manifestations include persistent headaches, nausea, vomiting, visual disturbances, drowsiness, and changes in mental state or behaviour. The specific presentation can vary depending on the tumour's size and exact location.

Diagnosing Central Neurocytoma

The diagnosis of central neurocytoma relies on detailed medical imaging. Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans are crucial for visualising the tumour, determining its size, location, and relationship to surrounding brain structures. These imaging techniques help differentiate central neurocytoma from other types of brain tumours and assess the extent of any associated hydrocephalus.

Treatment and Management of Central Neurocytoma

The primary treatment strategy for central neurocytoma is surgical removal, aiming for a gross total resection (GTR) where possible. For recurrent tumours or cases where complete surgical removal is not feasible, other therapeutic options may be considered. Radiation therapy is often recommended for residual or recurrent disease. Chemotherapy may also be employed for recurrent tumours. Long-term follow-up, including regular brain scans, is essential to monitor for any signs of tumour recurrence.

Alternative Terms and Coding for Central Neurocytoma

Central neurocytoma of brain (ICD-11 code 2A00.3) is also known by several synonyms, including Central neurocytoma and CNC. In medical documentation and billing, it is important to use the precise ICD-11 code. The ICD-11 code for central neurocytoma of brain is 2A00.3. Accurate coding is vital for reporting, statistical purposes, and reimbursement processes related to this specific brain tumour diagnosis.

When to Seek Medical Advice for Neurological Symptoms

Individuals experiencing persistent or concerning neurological symptoms, such as severe headaches, unexplained nausea or vomiting, vision changes, or alterations in behaviour or consciousness, should seek prompt medical evaluation. Early consultation with a healthcare professional is crucial for accurate diagnosis and appropriate management of potential brain conditions, including tumours like central neurocytoma.
