Small well-defined ovoid left adrenal mass measuring 20 x 18 x 16 mm with signal dropout on T1 GE opposed-phase images.
Case Discussion
MRI features of a well-defined left adrenal nodule with signal dropout on T1 opposed phase sequence consistent with an adrenal lipoma.
The MRI is usually performed to help define indeterminate adrenal lesions seen on CT. MRI is useful for adrenal masses with an attenuation <30 HU and demonstrates signal dropout on opposed-phase images in the majority of adenomas,
