Presentation

Small well-circumscribed rounded left adrenal mass (diametre = 13 mm) of inhomogeneous high signal on T1 GE in phase with signal loss on out of phase, intermediate signal on T2 with no significant enhancement on postcontrast sequences.
The gallbladder content appears of high signal on T1 and low signal on T2 suggestive of vicarious excretion of contrast (patient had a CT urography a few days ago).
Case Discussion
MRI features are most consistent with adrenal adenoma (incidental finding in this case).
Chemical shift MRI imaging has high sensitivity and specificity to identify an adrenal adenoma, especially when CT findings are equivocal.
