HydrocephalusLow pressure hydrocephalus: Low-pressure hydrocephalus (LPH) is a condition whereby ventricles are enlarged and the individual experiences severe dementia, inability to walk, and incontinence - despite very low intracranial pressure (ICP). Low pressure hydrocephalus appears to be a more acute form of normal pressure hydrocephalus.Shunt nephritisVentriculostomyVentricular system: The ventricular system is a set of four interconnected cavities (ventricles) in the brain, where the cerebrospinal fluid (CSF) is produced. Within each ventricle is a region of choroid plexus, a network of ependymal cells involved in the production of CSF.PneumoencephalographyTanycyteDiastematomyeliaIntracranial pressure monitoringReissner's fiber: Reissner's fiber is a fibrous aggregation of secreted molecules extending from the subcommissural organ (SCO) through the ventricular system and central canal to the ampulla caudalis, a small ventricle-like structure at the end of the spinal cord.Subarachnoid hemorrhageCerebellar hypoplasia: Cerebellar hypoplasia is a rare embryonic developmental disorder in which the cerebellum is either missing entirely or is smaller than usual. It may be genetic or occur sporadically.Ludwig G. KempeHyperintensityCerebral hemorrhageDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Arachnoid granulation: Arachnoid granulations (or arachnoid villi) are small protrusions of the arachnoid (the thin second layer covering the brain) through the dura mater (the thick outer layer). They protrude into the venous sinuses of the brain, and allow cerebrospinal fluid (CSF) to exit the sub-arachnoid space and enter the blood stream.Kaolin Mushroom Farms: Kaolin Mushroom Farms, Inc. is a fourth-generation family farm that began growing mushrooms in southern Chester County, Pennsylvania in 1925.Agenesis: In medicine, agenesis (Entry "agenesis" in Merriam-Webster Online Dictionary.) refers to the failure of an organ to develop during embryonic growth and development due to the absence of primordial tissue.PHACES Syndrome: Posterior fossa malformations–hemangiomas–arterial anomalies–cardiac defects–eye abnormalities–sternal cleft and supraumbilical raphe syndrome (also known as "PHACE Syndrome") is a cutaneous condition characterized by multiple congenital abnormalities.Hemispherectomy FoundationProphet Jeremiah (Michelangelo): The Prophet Jeremiah is one of the seven Old Testament prophets painted by the Italian High Renaissance master Michelangelo (c. 1542–1545) on the Sistine Chapel ceiling.Meningitis Vaccine ProjectChoroid plexus cystEpicanthic fold: Epicanthic fold (), epicanthal fold, epicanthus, or simply eye fold are names for a skin fold of the upper eyelid, covering the inner corner (medial canthus) of the eye. Other names for this trait include plica palpebronasalis and palpebronasal fold..
