Cavum Vergae

Cavum Vergae

The Cavum Vergae is a potential space in the brain, located between the corpus callosum and the fornix. It is considered an extension of the cavum septi pellucidi, which is a slit-like space between the two leaflets of the septum pellucidum. The Cavum Vergae is named after the Italian anatomist Andrea Verga, who first described it in the 19th century.

Anatomy

The Cavum Vergae is situated posterior to the cavum septi pellucidi and anterior to the splenium of the corpus callosum. It is bounded superiorly by the corpus callosum and inferiorly by the fornix. The space is typically obliterated during fetal development, but it can persist into adulthood in some individuals.

Clinical Significance

The presence of a Cavum Vergae is usually asymptomatic and is often discovered incidentally during neuroimaging studies such as MRI or CT scan. However, in rare cases, it can be associated with neurological disorders or developmental anomalies. It is important to differentiate the Cavum Vergae from other cystic lesions in the brain to avoid unnecessary interventions.

Imaging

On MRI, the Cavum Vergae appears as a fluid-filled space that is continuous with the cavum septi pellucidi. It is best visualized on sagittal and coronal sections. The space is typically hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging.

History

The Cavum Vergae was first described by Andrea Verga in 1851. Verga's work contributed significantly to the understanding of the anatomy and development of the ventricular system in the brain.
