Neoplasms Of Brain Or Central Nervous System – ICD 11 Codes

Definition of Neoplasms Of Brain Or Central Nervous System: A benign or malignant neoplasm that affects the brain, meninges, or spinal cord. Representative examples of primary neoplasms include astrocytoma, oligodendroglioma, ependymoma, and meningioma.

  2A00  Primary neoplasms of brain

2A00.0 Gliomas of brain

2A00.00 Glioblastoma of brain

Definition of Glioblastoma of brain: Glioblastomas are malignant astrocytic tumours (grade IV according to the WHO classification). They represent the most frequent brain tumours in adults. They may occur at any age, but 70% of cases are seen in patients between 45 and 70 years of age. The tumours are usually located in the brain hemispheres, but can be found anywhere in the central nervous system.

Inclusions:

  • glioblastoma NOS

2A00.0Y Other specified gliomas of brain

2A00.0Z Gliomas of brain unspecified

2A00.1 Embryonal tumours of brain

2A00.10 Medulloblastoma of brain

Definition of Medulloblastoma of brain: A malignant, invasive embryonal neoplasm arising from the cerebellum. It occurs predominantly in children and has the tendency to metastasize via the cerebrospinal fluid pathways. Signs and symptoms include truncal ataxia, disturbed gait, lethargy, headache, and vomiting. There are four histologic variants: anaplastic medulloblastoma, desmoplastic/nodular medulloblastoma, large cell medulloblastoma, and medulloblastoma with extensive nodularity.

2A00.11 Central primitive neuroectodermal tumour

Definition of Central primitive neuroectodermal tumour: A malignant neoplasm that originates in the neuroectoderm. The neuroectoderm constitutes the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems and includes some glial cell precursors.

2A00.1Z Embryonal tumours of brain unspecified

2A00.2 Tumours of neuroepithelial tissue of brain

2A00.20 Tumours of the pineal gland or pineal region

2A00.21 Mixed neuronal-glial tumours

2A00.22 Choroid plexus tumours

2A00.2Y Other specified tumours of neuroepithelial tissue of brain

2A00.2Z Tumours of neuroepithelial tissue of brain unspecified

2A00.3 Central neurocytoma of brain

Definition of Central neurocytoma of brain: Central neurocytoma is a very rare brain tumour of young adults. It is typically found in the lateral ventricles and occasionally in the third ventricle. Symptoms are those of increased intracranial pressure.

2A00.4 Astroblastoma of the brain

Definition of Astroblastoma of the brain: A rare glial neoplasm more commonly found in young adults. It is characterised by tumour cells with characteristics suggestive of an astrocytic origin (positive for GFAP), arranged perivascularly. The cells have broad, non-tapering processes radiating towards a central blood vessel. The biologic behaviour of astroblastomas is variable, so no WHO grade has been established, yet.

  • Neurofibroma (2F3Y)

2A02.10 Malignant peripheral nerve sheath tumour of cranial or paraspinal nerves

Definition of Malignant peripheral nerve sheath tumour of cranial or paraspinal nerves: Malignant schwannoma is a tumour of the peripheral nervous system that arises in the nerve sheath.

Exclusions:

  • Malignant nerve sheath tumour of peripheral nerves or autonomic nervous system, primary site (2B5E)

2A02.11 Paraspinal neuroblastoma

2A02.12 Malignant neoplasm of the optic nerve

2A02.2 Primary neoplasm of spinal cord of unknown or unspecified type

2A02.3 Benign neoplasm of cranial nerves

Definition of Benign neoplasm of cranial nerves: This is a tumour of cranial nerves having none of the characteristics of a malignant neoplasm.
