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.
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
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.
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 septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain. It runs as a sheet from the corpus callosum down to the fornix. The septum is not present in the syndrome septo-optic dysplasia.
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1]They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
