Understanding Mixed Neuronal-Glial Tumours

Mixed neuronal-glial tumours represent a category of central nervous system neoplasms characterised by a variable mix of neuronal and glial cell differentiation. These tumours are often classified as low-grade and tend to grow slowly. They are also referred to as glioneuronal tumours. The ICD-11 code for this condition is 2A00.21.

Alternative Names for Mixed Neuronal-Glial Tumours

Mixed neuronal-glial tumours are known by several other names, reflecting their complex nature. These include glioneuronal tumours, anaplastic ganglioglioma of the brain, desmoplastic infantile astrocytoma or ganglioglioma, dysembryoplastic neuroepithelial tumour of the brain, papillary glioneuronal tumour of the brain, rosette-forming glioneuronal tumour of the fourth ventricle, gangliocytoma of the brain, and ganglioglioma.

Recognising the Symptoms of Mixed Neuronal-Glial Tumours

The presentation of mixed neuronal-glial tumours can vary significantly depending on their location within the brain. Common symptoms include:
  • Seizures, which are often the initial sign
  • Headaches, which may be more severe when lying down
  • Nausea and vomiting
  • Dizziness and balance disturbances
  • Visual impairments
  • Changes in personality or confusion
  • Ataxia, or lack of voluntary muscle control

Diagnosing Mixed Neuronal-Glial Tumours and Seeking Help

The definitive diagnosis of a mixed neuronal-glial tumour typically involves an MRI scan to visualise the tumour, followed by a biopsy. This small sample of tumour tissue is removed during neurosurgery and analysed in a laboratory. If you experience symptoms such as persistent seizures, severe headaches, or neurological changes, it is crucial to seek prompt medical advice from a healthcare professional for accurate diagnosis and care.

Managing Mixed Neuronal-Glial Tumours

The primary treatment approach for mixed neuronal-glial tumours is often neurosurgery, aiming for complete tumour resection, which can lead to a cure in many instances. If complete removal is not feasible, further treatment options may include chemotherapy or radiotherapy. Patients may also have access to novel treatments through clinical trials.

Coding and Documentation for Mixed Neuronal-Glial Tumours

For accurate medical billing and record-keeping, the specific ICD-11 code for mixed neuronal-glial tumours is 2A00.21. When documenting patient cases, healthcare providers should include the official ICD-11 terminology and any relevant clinical details, such as symptoms, diagnostic findings, and treatment plans. This ensures precise reporting for statistical and administrative purposes.

Frequently asked questions

What is the ICD-11 classification and definition for Mixed neuronal-glial tumours?
The ICD-11 code for Mixed neuronal-glial tumours is 2A00.21. This classification encompasses central nervous system neoplasms characterized by a variable degree of neuronal and, less consistently, glial differentiation.
How is post-coordination used with the ICD-11 code 2A00.21 for Mixed neuronal-glial tumours?
ICD-11 allows for post-coordination with code 2A00.21 to add detail. This involves using stem and/or extension codes to specify laterality (e.g., left, right, bilateral) and specific anatomical sites or histopathological characteristics.
Can specific anatomical sites or histopathological features be coded alongside 2A00.21 in ICD-11?
Yes, ICD-11 permits post-coordination for code 2A00.21 to specify anatomical location and histopathology, allowing for more detailed coding of the tumour's characteristics.
What are some synonyms or related terms for Mixed neuronal-glial tumours in ICD-11?
Synonyms and related terms listed in ICD-11 for 2A00.21 include Anaplastic ganglioglioma of brain, Desmoplastic infantile astrocytoma or ganglioglioma, Dysembryoplastic neuroepithelial tumour of brain, Papillary glioneuronal tumour of brain, Rosette-forming glioneuronal tumour of the fourth ventricle, Gangliocytoma of brain, Ganglioglioma, glioneuronal of unspecified site, Nasal ganglioglioma, Ganglioneuroma of brain, neuroastrocytoma of unspecified site, Dysplastic cerebellar gangliocytoma, and Lhermitte-Duclos disease.
