Aim: To assess the measurements of posterior pituitary bright
spot on MRI in Khyber Pakhtunkhwa
was done in RMI, Peshawar. Duration is January, 2016 to February, 2019. 78
patients with normal pituitary MRI studies were selected for study. MRI without
contrast was done along cranio caudal and antero posterior axis on sagital
T1WI. Three cases of ectopic posterior pituitary were also included.
were taken in antero posterior and cranio caudal axis on sagittal T1WI. Dimension
of PPBS was 1.8--8.6mm in cranio caudal axis and 0.8-6mm in antero posteriorly. Mean±SD of cranio caudal measurement was 5.09±1.28mm
and of antero posteriorly 2.42±0.9mm. Pearsons analysis showed direct
correlation i.e. as value of cranio caudal diameter increased, the antero posteriorly
identified in 100% of normal pituitary glands. Mean PPBS size normally ranged
from 1.8 to 8mm i.e. mean± SD was 5.09±1.28mm craniocaudally. There is a direct
correlation in cranio caudal and antero posterior dimensions of PPBS.
