PH601 | Abscess, cerebellum | | a localised collection of pus caused by suppuration in the cerebellum |
PH602 | Cerebellum | | the portion of the brain in the back of the head between the cerebrum and the brain stem; it controls balance for walking and standing, and other complex motor functions |
PH603 | Cerebral hemorrhage | cerebral haemorrhage | a sudden and abrupt bleeding into the tissue of the brain; usually occurs as the result of a weakened artery from the effects of high blood pressure and atherosclerosis |
PH604 | Cerebral softening | | a localised softening of the brain substance due to inflammation or haemorrhage localized softening of the brain substance, due to hemorrhage or inflammation |
PH605 | Cerebrum | | the largest part of the brain, controlling muscle functions speech, thought, emotions, reading, writing, and learning |
PH606 | Dementia, paralytica | paralytic dementia | dementia and paralysis resulting from a chronic syphilitic meningoencephalitis |
PH607 | Encephalitis, post-vaccinal | | inflammation of the brain as a result of vaccination |
PH608 | Glioblastoma multiforme | | a malignant brain tumour that accounts for 75% of glial tumours (arising from glial cells in the brain). |
PH609 | Hippocampus | | part of the limbic system of the brain, involved in emotions and memory |
PH610 | Infarct, cortical, brain | | tissue death due to a local lack of oxygen in the cerebral cortex (outer layer that covers the cerebrum, functions chiefly in coordination of sensory and motor information) |
PH611 | Infarct, old, cerebellum | | an old area of tissue death due to a local lack of oxygen in the cerebellum (concerned especially with the coordination of muscles and the maintenance of bodily equilibrium) |
PH612 | Medulla oblongata | | lower part of brain stem; controls autonomic functions; relays nerve signals between the brain and spinal cord |
PH613 | Meningioma, brain | | common benign brain tumour that originates in the cells of the outer covering of the brain (meninges) |
PH614 | Meningioma, brain, malignant | | malignant tumour the cells of the outer covering of the brain (meninges) |
PH615 | Meningitis with cortical oedema | | inflammation of the meninges with fluid retention in the cortex |
PH616 | Meningitis, pneumococcal | | inflammation of the meninges of the brain as a result of infection by strep pneumoniae |
PH617 | Meningitis, tuberculous | | inflammation of the meninges of the brain as a result of tuberculosis |
PH618 | Nerve | | a bundle of fibers that uses electrical and chemical signals to transmit sensory and motor information from one body part to another |
PH619 | Nerve, peripheral | | the nerves outside of the brain and spinal cord; they contain non-neuronal cells and connective tissue as well as axons |
PH620 | Neuroblastoma | | cancer that arises in immature nerve cells and affects mostly infants and children |
PH621 | Neurofibroma | | a benign tumor that develops from the cells and tissues that cover nerves |
PH622 | Pilocytic astrocytoma, brain | juvenile astrocytoma | a nerve-tissue tumor composed of astrocytes; the most common brain tumor in children |
PH623 | Sympathetic ganglion | | a group of nerve cell bodies either close to the spinal column or close to the large abdominal arteries |
PH624 | Thalamus | | a large mass of gray matter deeply situated in the forebrain; relays information received from various brain regions to the cerebral cortex |
PH625 | Toxoplasmosis, brain | | brain showing symptoms caused by toxoplasma gondii, often contacted via cat faeces |
