Abstract
Objective
Our aim was to investigate the statistical preoperative diagnostic criteria of lesions
of Meckel's cave (MC) on MRI.
Materials and methods
We retrospectively reviewed the MR images with MC lesions in 34 patients. The MR signs
were compared with histopathologic and surgical findings in all lesions. Odds ratio
values and the confidence intervals of the MRI diagnostic criteria were evaluated
by univariate logistic regression.
Results
The following three signs of MC on post-contrast T1WI of MRI have been found to represent
the most valuable criterion for determination of MC lesion: (1) contrast enhancement,
(2) bulging of lateral wall, and (3) the absence of normal MC, with odds ratios of
362.67 (P<.001), 40.38 (P=.001), and 40.38 (P=.001) individually.
Conclusion
Contrast enhancement on post-contrast T1WI is the most sensitive MR sign for demonstrating
the presence of MC lesion.
