Lateral ventricles asymmetry, or an asymmetry with midline shift or diffuse enlargement, may indicate brain injury early in life, particularly in cases of a longer right occipital horn. Lateral ventricles The lateral ventricles are the two largest cavities of the ventricular system of the human brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively. Each lateral ventricle resembles a C-shaped structure that begins at an inferior horn in the temporal lobe, travels through a body in the parietal lobe and frontal lobe, and ultimately terminates at the interventricular foramina where
Lateral ventricles using linear or planar measurements. The volume of the lateral ventricles are known to increase with age. They are also enlarged in a number of neurological conditions and are on average larger in patients with schizophrenia, bipolar disorder, major depressive disorder and Alzheimer's disease. Asymmetry in the size of the lateral ventricles is found in about 5–12% of the population. It has been associated with handedness, where right-handed people have been found to have a larger right lateral ventricle and a longer left occipital horn, whereas left handed people have been found to have longer right occipital horns.
