Tela Choroidea (Rear View)

Description

Tela choroidea fills the posterior field as a thin, vascular connective tissue layer draped along the ventricular roof. From this rear perspective, its midline attachment sits medial to the paired thalami, while its lateral margins approach the choroid fissures near the fimbria of the hippocampus and the fornix. Fine vascular channels course within the membrane in a pattern consistent with choroid plexus supply and drainage, oriented superior to the ventricular cavity and deep to the overlying cerebral hemispheric tissue. Depth cues emphasize the separation between the tela and the surrounding ependymal-lined ventricle. Neurosurgeons and neuroradiologists care about this membrane because it frames the corridor of the velum interpositum and the internal cerebral venous complex, where even small variations can matter during endoscopic navigation and when interpreting intraventricular blood or enhancing tissue. A posterior view is also the most instructive angle for appreciating how the choroid fissure opens into the lateral ventricle and how the vascular stroma of the tela relates to the region where choroid plexus papilloma, meningioma of the velum interpositum, or choroid plexus hemorrhage may present as an intraventricular mass or cause obstructive hydrocephalus. No guessing required. The controlled lighting favors the membrane’s translucency while keeping the ventricular boundaries readable, so you can separate tela choroidea from adjacent neural parenchyma at a glance. Use this illustration in neuroanatomy laboratory manuals, ventricular system lectures, and figure plates for papers discussing intraventricular tumors, hydrocephalus pathways, or endoscopic third ventriculostomy landmarks where the roof of the third ventricle and venous relationships must be stated precisely.
