Objective: Craniopharyngiomas pose a baffling problem to neurosurgeons because of the difficulty in total
removal and tendency to recur even operated by experienced hands. We propose a new classification or grading
system of craniopharyngiomas based on MRI findings including not only sagittal diameter but also coronal diameter of
the tumor, the usefulness of which was evaluated in 100 consecutive patients mainly operated by one neurosurgeon
(T.H.).
Methods: Between 1981 and 2012, 100 patients comprising 55 males and 45 females aged from 1 year to 75
years (mean 33.1 ± 22.7) underwent surgeries for craniopharyngiomas, including endoscopic removal in two patients.
Thirty-six pediatric (younger than 15 years) patients comprising 23 males and 13 females with a mean age of 8.1 ± 4.3
years were included. Surgeries were co.. View More»
