Frontal Horn Of The Ventricles (Superior View)

Description

Frontal horns of the lateral ventricles occupy the anteromedial portions of each cerebral hemisphere, and in this superior perspective their paired lumina diverge laterally as they extend forward from the region of the interventricular foramina. Medially, the two horns approach the midline where the septum pellucidum normally separates them, while the roof is formed by the corpus callosum, most conspicuously its anterior body and genu in this orientation. Along the inferolateral margin, the head of the caudate nucleus creates a characteristic ventricular impression, with the anterior limb of the internal capsule lying lateral to it. Midline symmetry is easy to judge. These relationships matter in everyday neuroradiology because the frontal horns are a reference for ventricular size and configuration on axial CT and MRI, including the assessment of hydrocephalus and the frontal horn ratio used in normal pressure hydrocephalus workups. Their anterior location also frames common neurosurgical corridors, since frontal horn catheter placement for external ventricular drainage targets the ventricular cavity while avoiding the caudate head and traversing white matter tracts. The fixed superior viewpoint makes the lateral angulation of the horns unambiguous, a detail that can be lost when learners only see ventricles as a continuous C shaped space. Use this illustration in neuroanatomy teaching on the ventricular system, in radiology atlases that correlate gross anatomy with axial imaging, or in neurosurgery materials explaining landmarks for frontal ventriculostomy and intraventricular hemorrhage tracking.
