Clinical Classification

Clinical Information

  • Basal Ganglia

    large subcortical nuclear masses derived from the telencephalon and located in the basal regions of the cerebral hemispheres.
  • Basal Ganglia Cerebrovascular Disease

    a pathological condition caused by impaired blood flow in the basal regions of cerebral hemispheres (basal ganglia), such as infarction; hemorrhage; or ischemia in vessels of this brain region including the lateral lenticulostriate arteries. primary clinical manifestations include involuntary movements (dyskinesias) and muscle weakness (hemiparesis).
  • Basal Ganglia Diseases

    diseases of the basal ganglia including the putamen; globus pallidus; claustrum; amygdala; and caudate nucleus. dyskinesias (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. common etiologies include cerebrovascular disorders; neurodegenerative diseases; and craniocerebral trauma.
  • Basal Ganglia Hemorrhage

    bleeding within the subcortical regions of cerebral hemispheres (basal ganglia). it is often associated with hypertension or arteriovenous malformations. clinical manifestations may include headache; dyskinesias; and hemiparesis.
  • Globus Pallidus

    the representation of the phylogenetically oldest part of the corpus striatum called the paleostriatum. it forms the smaller, more medial part of the lentiform nucleus.
  • Anterior Hypothalamic Nucleus

    loose heterogeneous collection of cells in the anterior hypothalamus, continuous rostrally with the medial and lateral preoptic areas and caudally with the tuber cinereum.
  • Arcuate Nucleus of Hypothalamus

    a nucleus located in the middle hypothalamus in the most ventral part of the third ventricle near the entrance of the infundibular recess. its small cells are in close contact with the ependyma.
  • Hypothalamic Area, Lateral

    area in the hypothalamus bounded medially by the mammillothalamic tract and the anterior column of the fornix (brain). the medial edge of the internal capsule and the subthalamic region form its lateral boundary. it contains the lateral hypothalamic nucleus, tuberomammillary nucleus, lateral tuberal nuclei, and fibers of the medial forebrain bundle.
  • Hypothalamic Neoplasms

    benign and malignant tumors of the hypothalamus. pilocytic astrocytomas and hamartomas are relatively frequent histologic types. neoplasms of the hypothalamus frequently originate from adjacent structures, including the optic chiasm, optic nerve (see optic nerve neoplasms), and pituitary gland (see pituitary neoplasms). relatively frequent clinical manifestations include visual loss, developmental delay, macrocephaly, and precocious puberty. (from devita et al., cancer: principles and practice of oncology, 5th ed, p2051)
  • Hypothalamus

    ventral part of the diencephalon extending from the region of the optic chiasm to the caudal border of the mammillary bodies and forming the inferior and lateral walls of the third ventricle.
  • Hypothalamus, Anterior

    the front portion of the hypothalamus separated into the preoptic region and the supraoptic region. the preoptic region is made up of the periventricular gray matter of the rostral portion of the third ventricle and contains the preoptic ventricular nucleus and the medial preoptic nucleus. the supraoptic region contains the paraventricular hypothalamic nucleus, the supraoptic nucleus, the anterior hypothalamic nucleus, and the suprachiasmatic nucleus.
  • Hypothalamus, Middle

    middle portion of the hypothalamus containing the arcuate, dorsomedial, ventromedial nuclei, the tuber cinereum and the pituitary gland.
  • Hypothalamus, Posterior

    the part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial maxillary nucleus, lateral mammillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). the posterior hypothalamic area is concerned with control of sympathetic responses and is sensitive to conditions of decreasing temperature and controls the mechanisms for the conservation and increased production of heat.
  • Pituitary Gland

    a small, unpaired gland situated in the sella turcica. it is connected to the hypothalamus by a short stalk which is called the infundibulum.
  • Supraoptic Nucleus

    hypothalamic nucleus overlying the beginning of the optic tract.
  • Putamen

    the largest and most lateral of the basal ganglia lying between the lateral medullary lamina of the globus pallidus and the external capsule. it is part of the neostriatum and forms part of the lentiform nucleus along with the globus pallidus.
  • Putaminal Hemorrhage

    intracranial bleeding into the putamen, a basal ganglia nucleus. this is associated with hypertension and lipohyalinosis of small blood vessels in the putamen. clinical manifestations vary with the size of hemorrhage, but include hemiparesis; headache; and alterations of consciousness.
  • Anterior Thalamic Nuclei

    three nuclei located beneath the dorsal surface of the most rostral part of the thalamus. the group includes the anterodorsal nucleus, anteromedial nucleus, and anteroventral nucleus. all receive connections from the mamillary body and brain fornix, and project fibers to the cingulate body.
  • Intralaminar Thalamic Nuclei

    cell groups within the internal medullary lamina of the thalamus. they include a rostral division comprising the paracentral, central lateral, central dorsal, and central medial nuclei, and a caudal division composed of the centromedian and parafascicular nuclei.
  • Mediodorsal Thalamic Nucleus

    the largest of the medial nuclei of the thalamus. it makes extensive connections with most of the other thalamic nuclei.
  • Midline Thalamic Nuclei

    small, nonspecific nerve cells scattered in the periventricular gray matter, separating the medial part of the thalamus from the ependyma of the third ventricle. the group includes the paraventricular nucleus, paratenial nucleus, reuniens nucleus, rhomboidal nucleus, and subfascular nucleus.
  • Posterior Thalamic Nuclei

    a transitional diencephalic zone of the thalamus consisting of complex and varied cells lying caudal to the ventral posterolateral nucleus, medial to the rostral part of the pulvinar, and dorsal to the medial geniculate body. it contains the limitans, posterior, suprageniculate, and submedial nuclei.
  • Pulvinar

    large mass of nuclei forming the most caudal portion of the thalamus and overhanging the geniculate bodies and the dorsolateral surface of the midbrain. it is divided into four parts: the lateral, medial, inferior, and oral pulvinar nuclei.
  • Thalamus

    paired bodies containing mostly gray matter and forming part of the lateral wall of the third ventricle of the brain.
  • Ventral Thalamic Nuclei

    a large group of nuclei lying between the internal medullary lamina and the internal capsule. it includes the ventral anterior, ventral lateral, and ventral posterior nuclei.
  • Metastatic Neuroblastoma

    a neuroblastoma that has metastasized from its original site of growth to another anatomic site.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


Brain Tumors

A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.

Brain tumors can cause many symptoms. Some of the most common are:

  • Headaches, often in the morning
  • Nausea and vomiting
  • Changes in your ability to talk, hear, or see
  • Problems with balance or walking
  • Problems with thinking or memory
  • Feeling weak or sleepy
  • Changes in your mood or behavior
  • Seizures

Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses drugs or other substances that attack cancer cells with less harm to normal cells. Many people get a combination of treatments.
