title: Three-Dimensional Microsurgical Anatomy of the Choroid Plexus Using the Volume Rendering Technique.
abstract: OBJECTIVE
  The choroid plexus (CP) is a specific anatomical structure producing cerebrospinal fluid into the ventricular space. The three-dimensional anatomical structure of the choroid plexus located within the lateral ventricle may be evaluated by using the three dimensional volume rendering technique (3D-VRT) from acquired two-dimensional contrast enhanced computerized tomographic images.
  
  
  METHODS
  The raw data of Three-dimensional Computerized Tomography Angiography (3D-CTA) were transferred into the computer and recorded in a software program. These images were evaluated in terms of anatomical shape, borders, extensions length and dimensions.
  
  
  RESULTS
  The patient group consisted of 57 (27 female and 30 male) patients. The mean age of the patients was 55±9 years. In male individuals, the distance of the superior tip from Frazier's point was 7.96±0.71 centimeters at the right side. In males, the distance of the inferior tip of the CP was estimated as 1.93±0.26 centimeters posterior-lateral from the anterior clinoid process, 1.64±0.23 centimeters posterior-lateral from the bifurcation of internal carotid artery, and 2.86±0.23 centimeters posterior-medial from the bifurcation of middle cerebral artery on the right side.
  
  
  CONCLUSIONS
  The results of this study showed us that this technique could be used in the three-dimensional evaluation of some anatomical structures such as the choroid plexus.
