The anterior horn of the lateral ventricle is also known as the frontal horn as it extends into the frontal lobe. The anterior horn connects to the third ventricle, via the interventricular foramen. [1] This portion of the lateral ventricle impinges on the frontal lobe, passing anteriorly and laterally, with slight inclination inferiorly.
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 ]
The calcar avis, previously known as the hippocampus minor, [1] is an involution of the wall of the lateral ventricle's posterior cornu produced by the calcarine fissure. [ 2 ] It is sometimes visible on ultrasonogram [ 3 ] and can resemble a clot .
The term anterior horn (also frontal horn, anterior cornu, frontal cornu) may refer to either of two separate anatomical structures within the central nervous system: anterior horn of lateral ventricle in the brain, which passes forward, laterally, and slightly downward from the interventricular foramen into the frontal lobe
Kocher's point is a common entry point through the frontal bone for an intraventricular catheter to drain cerebrospinal fluid from the anterior horn of the lateral ventricle. It is located 2–3 centimeters lateral to the midline (at approximately the mid-pupillary line) and approximately 11 cm posterior to the nasion , or 10 cm posterior from ...
The lateral ventricles sit on either side of the septum. The septum pellucidum consists of two layers or laminae of both white and gray matter . [ 1 ] During fetal development, there is a space between the two laminae called the cave of septum pellucidum that, in ninety percent of cases, disappears during infancy.
Colpocephaly is a cephalic disorder involving the disproportionate enlargement of the occipital horns of the lateral ventricles and is usually diagnosed early after birth due to seizures. It is a nonspecific finding and is associated with multiple neurological syndromes , including agenesis of the corpus callosum , Chiari malformation ...
Drains towards the frontal horn of the lateral ventricles. Cerebellar hemisphere: 14–27% Drains into the fourth ventricle. Diagnosis.
