Magnetic resonance image (MRI) showing pituitary tumour. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties. Pituitary tumours may compress adjacent structures, including the hypothalamus, several cranial nerves, and the optic chiasm. Chiasmal compression may result in bitemporal hemianopsia.

Magnetic resonance image (MRI), axial section, of 4-year-old child with grade II astrocytoma and epilepsy. See also N0014116-14117 Astrocytomas are neoplasms of the brain and spinal cord derived from glial cells which vary from histologically benign forms to highly anaplastic and malignant tumours. Fibrillary astrocytomas are the most common type and may be classified in order of increasing malignancy (grades I through IV). In the first two decades of life, astrocytomas tend to originate in the cerebellar hemispheres; in adults, they most frequently arise in the cerebrum and frequently undergo malignant transformation.

Axial magnetic resonance image (MRI) showing glioma in corpus callosum. Gliomas are benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes).

Magnetic resonance image (MRI), coronal slice, of 10-year-old child with disembryoplastic neuroepithelial (primitive neuroectodermal) tumour and epileptic fits. See also N0014119 and 14121. These are a group of malignant tumours of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. In general, these tumours arise in the first decade of life and tend to be highly malignant.

Magnetic resonance image (MRI) showing multicentre glioblastoma. This is a malignant form of astrocytoma histologically characterized by pleomorphism of cells, nuclear atypia, microhaemorrhage, and necrosis. They may arise in any region of the central nervous system, with a predilection for the cerebral hemispheres, basal ganglia, and commissural pathways. Clinical presentation most frequently occurs in the fifth or sixth decade of life with focal neurologic signs or seizures.
