Abstract
Magnetic Resonance Imaging provides
sufficient high resolution to analyzed the size, shape and
appearance of the pituitary gland. So far, no research has been
performed with regards to the morphology and measurement
of pituitary gland in Kelantan population. The aim was to
determine the measurement and morphology of normal
pituitary gland in the population of this state. This prospective
study was done from June 1999 till December 2000 in HUSM,
Kubang Kerion. Inclusion criteria for this study include no clinical
finding suggestive of pituitary disease or significant endocrine
disturbance for the initial radiological referral. Midline noncontrast-
enhanced Tl-Weighted Images (TlWI) via sagittal
images was used exclusively for the analysis.
Total of eighty patients were included in this study with
age of patients range from 0.08 to 87 years. The mean height of
the gland in male patient was 5.56 mm ± (SD 1.596) and for
female 5.97 mm ± SD 1.76. In the age group of 10 to 19 years
old, an increase in size and convexity of the pituitary gland
presence during adolescence. The mean height, length and
width of the infant pituitary gland were 3.56 mm, 6.20 mm and
5.61 mm respectively. The signal intensity in the anterior lobe of
the pituitary gland in infant was of high signal intensity relative
to the pons. The posterior lobe demonstrated high signal
intensity in 62 patients (77.50fo). The mean diameter of the
infundibulum on coronal view was 1.854 mm with range of 0.5 to 3.9mm.
This study confirms that there were correlation
between the age pituitary size and shape. It also provides data
and information regarding normal variants of the pituitary gland.
