Background:Assessmentof pituitary macroadenomaconsistency before surgical resection is crucial for
neurosurgeonsto choose the surgical procedure. So, we sought to evaluatethe multiparametric MRI role as a
noninvasive method in predicting pituitary macroadenoma consistency
PatientsandMethods:AtZagazig University Hospitals, a multiparametric MRI was scheduled fortwenty-four
patients with pituitary macroadenoma. We determined the tumor consistency both macroscopically by
neurosurgeons and microscopically by histopathologists.
Results:The consistency of the pituitary macroadenoma and the T2 weighted image (T2 WI) signal intensities
were found to have a significant association as well as DWI & the corresponding ADC values, while we found
no correlation between the post contrast T1 weighted image patterns of enhancement and the tumor consistency.
Conclusions:As part of the usual pre-operativemacroadenoma consistency check, T2 WI, DWIand the
corresponding ADC value were shown to be able to detect macroadenomas consistency with high accuracy.
