한국인 정상뇌하수체의 형태조직학적 소견 및 영상진단(전산화단층촬영과 자기공명영 상) 소견과의 상관관계에 대한 고찰 = Histomorphologic Study of the Pituitary Glands of Korean cadavers and correlation with Computed Tomography and Magnetic resonance Imaging

다국어 초록 (Multilingual Abstract)

Histomorphological analysis of the pituitary glands of 62 Korean adult cadavers ws per-formed and its results were compared to the findings of high resolution CT scan in 6 cases and magnetic resonanc imaging in 2 cases The CT attenuation density of pituitary glands was also evaluated with coronal scans of 103 normal Korean adults who had no clinical evidence of pituitary abnormalities. The pituitary gland was classified into 4 type based on the contours of superior margin of the glands; slightly convex(type I & type II) slightly concave(type III) and deeply concave (type IV). Among them type III was the most common(44.4%) The size and shape of each lobe of gland were varied. The mean length and height of gland were 10.9$\pm$1.4mm and 4.6$\pm$1.2mm. Rathke's cleft cysts were commonly located at the middle one third between anterior lobe and pars intermedia of pituitary gland. The CT attenuation density of pituitary gland varied depending on the anatomic location and was roughly corresponding to the compactness of cellularity. Focal low attenuation density areas could be considered to represent Rathke's cleft cysts. In one of two pituitary glands the posterior lobe showed high signal intesity in T1-weighted MRI. which was not corresponding to the intrasellar fat pad or cellularity of gland.
