The symptoms vary greatly, in part, because of the underlying or causing infection. While the inflammation can cause a number of effects such as those mentioned previously, the base infection could cause other symptoms that don't necessarily have to do with the ventriculitis, itself. One of the challenges doctors face in diagnosing ...
Normal pressure hydrocephalus (NPH) is a form of chronic communicating hydrocephalus, with enlarged cerebral ventricles and intermittently increased cerebrospinal fluid pressure [47] [33]. The symptoms include dementia, gait changes, and urinary incontinence [33]. It is diagnosed with continuous intraventricular pressure recordings (over 24 ...
Increased volume of the ventricles will result in higher pressure within the ventricles, and cause higher pressure in the cortex from it being pushed into the skull. A person may have aqueductal stenosis for years without any symptoms, and a head trauma, hemorrhage, or infection could suddenly invoke those symptoms and worsen the blockage. [4]
Ventriculomegaly is a brain condition that mainly occurs in the fetus when the lateral ventricles become dilated. The most common definition uses a width of the atrium of the lateral ventricle of greater than 10 mm. [ 1 ] This occurs in around 1% of pregnancies. [ 2 ]
Grade III - ventricles are enlarged by the accumulated blood; Grade IV - bleeding extends into the brain tissue around the ventricles; Grades I and II are most common, and often there are no further complications. Grades III and IV are the most serious and may result in long-term brain injury to the infant.
Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.

Classical lissencephaly, also known as type I or generalized agyria-pachygyria, is a severe brain malformation of a smooth cerebral surface, abnormally thick (10–20 mm) cortex with four layers, widespread neuronal heterotopia, enlarged ventricles, and agenesis or malformation of the corpus callosum.
