an abnormal condition in which cerebrospinal fluid collects in the ventricles of the brain; in infants it can cause abnormally rapid growth of the head and bulging fontanelles and a small face; in adults the symptoms are primarily neurological
A usually congenital condition in which an abnormal accumulation of fluid in the cerebral ventricles causes enlargement of the skull and compression of the brain, destroying much of the neural tissue
an accumulation of liquid within the cavity of the cranium, especially within the ventricles of the brain; dropsy of the brain. It is due usually to tubercular meningitis. When it occurs in infancy, it often enlarges the head enormously
Origin: [NL., fr. Gr. hydrocephalus; "y`dwr water + head.]
Hydrocephalus, also known as "water on the brain," is a medical condition in which there is an abnormal accumulation of cerebrospinal fluid in the ventricles, or cavities, of the brain. This may cause increased intracranial pressure inside the skull and progressive enlargement of the head, convulsion, tunnel vision, and mental disability. Hydrocephalus can also cause death. The name is derived from the ancient Greek word ὑδροκέφαλον, hudroképhalon, translated as "water in the head" or verbatim as "water-headed". This word is short for τὸ ὑδροκέφαλον πάθος, to hudroképhalon páthos, "the sufffering from water in the head". The ancient Greek ὑδροκέφαλον, hudroképhalon is composed of the words ὕδωρ, húdōr, "water", and κεφαλή, kephalé, "head".
Chambers 20th Century Dictionary
hī-dro-sef′a-lus, n. an accumulation of serous fluid within the cranial cavity, either in the sub-dural space or the ventricles: water in the head: dropsy of the brain.—adjs. Hydrocephal′ic, Hydroceph′aloid, Hydroceph′alous. [Gr. hydōr, water, kephalē, the head.]
U.S. National Library of Medicine
Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, INTRACRANIAL HYPERTENSION; HEADACHE; lethargy; URINARY INCONTINENCE; and ATAXIA (and in infants macrocephaly). This condition may be caused by obstruction of cerebrospinal fluid pathways due to neurologic abnormalities, INTRACRANIAL HEMORRHAGES; CENTRAL NERVOUS SYSTEM INFECTIONS; BRAIN NEOPLASMS; CRANIOCEREBRAL TRAUMA; and other conditions. Impaired resorption of cerebrospinal fluid from the arachnoid villi results in a communicating form of hydrocephalus. Hydrocephalus ex-vacuo refers to ventricular dilation that occurs as a result of brain substance loss from CEREBRAL INFARCTION and other conditions.
