This study used 81 adult cadaver cerebral hemispheres without macroscopic pathology, fixed with 10 % formalin to investigate the morphometry of the anterior commissure, pineal body and massa intermedia which are in close relation with the third ventricle.
We observed the anterior-posterior distance of the anterior commissure as 2.5±0.56 mm (max. 3.8-min. 1.1 mm), and height as 3.9±0.8 mm (max. 5.8-min. 1.84 mm).
The distance of the intermediate mass to the cerebral fornix was measured as 5.25±1.78 mm (max. 9.2-min. 1.44 mm). The distances of massa intermedia to the interventricular foramen and to the lowest point of the ventricle were 4±0.91 mm (max. 6.3-min. 2.5 mm.) and 6.26±1.26 mm (max. 8.2-min. 3.1 mm), consequently. The distance of the massa intermedia to the anterior commissure was 6.58±1.2 mm (max. 9.04-min. 4.22 mm), and the posterior commissure was 9.76±2.08 mm (max. 13-min. 3.1 mm). The anterior-posterior distance of the pineal body was 6.62±1.5 mm (max. 9.3-min. 1.88 mm.) and the height was 3.78±0.65 mm (max. 5-min. 2.4 mm.)

Bu çalışmada 81 adet % 10 formalin ile fikse edilmiş ve herhangi bir makroskobik patoloji içermeyen erişkin kadavra beyni kullanılarak ventriculus tertius ile yakın komşulukları bulunan commissura anterior, corpus pineale ve massa intermedia morfometrik olarak incelenmiştir.
Ölçümlerimizde commissura anterior’un ön-arka mesafesi 2.5±0.56 mm (3.8-1.1 mm.), yüksekliği ise 3.9±0.8 mm (5.8-1.84 mm.) olarak gözlendi.
Massa intermedia’nın fornix cerebri’ye olan uzaklığı 5.25±1.78 mm (9.2-1.44 mm.) olarak saptandı. Massa intermedia foramen interventriculare’ye 4±0.91 mm (6.3-2.5 mm.), ven-trikül tabanına ise 6.26±1.26 mm (8.2-3.1 mm.) uzaklıktaydı. Ayrıca massa intermedia, commissura anterior’a 6.58±1.2 mm (9.04-4.22 mm.), commissura posterior’a ise 9.76±2.08 mm (13-3.1 mm.) mesafede saptandı.
Son aşamada ise corpus pineale’nin ön-arka mesafesi 6.62± 1.5 mm (9.3-1.88 mm.), yüksekliği ise 3.78±0.65 mm (5-2.4 mm) olarak saptandı.
