Three-Dimensional Microsurgical Anatomy of the Choroid Plexus Using the Volume Rendering Technique

Area of Science:

• Neuroanatomy
• Medical Imaging
• Radiology

Background:

• The choroid plexus (CP) is a vital structure responsible for cerebrospinal fluid production within the brain's ventricular system.
• Accurate three-dimensional anatomical assessment of the CP is crucial for understanding its role and potential pathologies.

Purpose of the Study:

• To evaluate the three-dimensional anatomical structure of the choroid plexus (CP) within the lateral ventricle.
• To assess the utility of the three-dimensional volume rendering technique (3D-VRT) for CP visualization using contrast-enhanced computed tomographic images.

Main Methods:

• Utilized Three-dimensional Computerized Tomography Angiography (3D-CTA) raw data.
• Processed images using specialized software for detailed anatomical evaluation.
• Analyzed CP shape, borders, extensions, length, and dimensions.

Main Results:

• The study included 57 patients (27 female, 30 male) with a mean age of 55±9 years.
• Detailed measurements of the CP's superior and inferior tips relative to anatomical landmarks were recorded in male individuals.
• Specific distances from Frazier's point, anterior clinoid process, and internal carotid artery bifurcation were quantified.

Conclusions:

• The three-dimensional volume rendering technique (3D-VRT) is a viable method for the three-dimensional evaluation of the choroid plexus.
• This imaging modality offers precise anatomical insights into the CP, aiding in neuroanatomical studies and clinical assessments.
