HPO HP:0012480 Abnormal cerebral vein morphology "An anomaly of cerebral veins." [HPO:probinson] HP:0100659
HPO HP:0012481 Cerebral venous angioma "A congenital malformation of veins which drain normal brain characterized by a caput medusae or an umbrellalike convergence of multiple venules on a single, or occasionally multiple, enlarged parenchymal or medullary vein, like the trunk of a tree or the shank of an umbrella. This dilated terminal vein penetrates the cortex to drain either (a) superficially to cortical veins or sinuses, (b) deeply to subependymal veins of the lateral ventricle and then into the galenic system, (c) to the fourth ventricle and then to the pontomesencephalic vein, or (d) to the precentral cerebellar vein and into the galenic system." [HPO:probinson, PMID:8770251] DVA is characterized by a caput medusae or an umbrellalike convergence of multiple venules on a single, or occasionally multiple, enlarged parenchymal or medullary vein, like the trunk of a tree or the shank of an umbrella. This dilated terminal vein penetrates the cortex to drain either (a) superficially to cortical veins or sinuses, (b) deeply to subependymal veins of the lateral ventricle and then into the galenic system, (c) to the fourth ventricle and then to the pontomesencephalic vein, or (d) to the precentral cerebellar vein and into the galenic system.

HPO HP:0012482 Frontal venous angioma "A venous angioma of the frontal lobe of the brain." [HPO:probinson] HP:0012481
HPO HP:0012483 Abnormal alpha granules "Defective structure, size or content of alpha granules, platelet organelles that contain several growth factors destined for release during platelet activation at sites of vessel wall injury." [DDD:wouwehand, PMID:8467233] This feature can be observed by electron microscopy. Alpha granules normally contain a number of proteins including von Willebrand factor, and fibrinogen. HP:0011883
HPO HP:0012484 Abnormal dense granules "Defective structure, size or content of dense granules, platelet organelles that contain granules proaggregatory factors such as adenosine diphosphate (ADP), adenosine triphosphate (ATP), ionized calcium, histamine and serotonin." [DDD:wouwehand] This feature can be observed by electron microscopy. HP:0011883
HPO HP:0012485 Abnormal surface-connected open canalicular system "An anomaly of the invaginations of the surface membrane that form the open canalicular system (OCS). The OCS serve as the pathway for transport of substances into the cells and as conduits for the discharge of alpha granule products secreted during the platelet release reaction." [HPO:probinson, PMID:1760557] HP:0011875
HPO HP:0012486 Myelitis "Inflammation of the spinal cord." [HPO:probinson] HP:0002143, HP:0033429
HPO HP:0012487 Cerebellopontine angle arachnoid cyst "An arachnoid cyst located at the margin of the cerebellum and pons." [ORCID:0000-0001-5208-3432] The cerebellopontine angle is in the posterior fossa. HP:0007291, HP:0100702
HPO HP:0012488 Intraventricular arachnoid cyst "An arachnoid cyst located within the ventricular system." [HPO:probinson, PMID:8951893] Arachnoid cysts very rarely occur within the ventricular system, where no arachnoid tissue exists. HP:0010576, HP:0100702
HPO HP:0012489 Suprasellar arachnoid cyst "An arachnoid cyst that progressively enlarges from an abnormality in the membrane of Liliequist or in the interpeduncular cistern, and typically, expands from the prepontine space, displacing the floor of the third ventricle upwards, the pituitary stalk and optic chiasm upwards and forwards, and the mammillary bodies upwards and backwards." [HPO:probinson, PMID:21586175] As the cyst increases in size it fills and occludes the third ventricle, and distorts and blocks the aqueduct, which finally results in hydrocephalus. HP:0010576, HP:0100702
HPO HP:0012490 Panniculitis "Inflammation of adipose tissue." [HPO:probinson] Panniculitis most commonly affects the skin and characterized by reddened subcutaneous nodules. HP:0009124, HP:0012649
HPO HP:0012491 Abnormal dense tubular system "An anomaly of the intracellular membrane complexes known as the dense tubular system." [DDD:wouwehand, PMID:1322202] The dense tubular system (DTS) functions to regulate platelet activation by sequestering or releasing calcium, similar to the sarcotubules of skeletal muscle. In resting platelets, the DTS exists as thin elongated membranes. Within 10 seconds of the addition of thrombin, platelets show a major ultrastructural change in their DTS: from the thin elongated form to a rounded vesicular form. HP:0011875
