Chemical shift imaging in diagnosis of adrenal adenoma.

A 65 yrs old male patient and a known case of carcinoma of prostate with finding of a small adrenal mass on CT scan. MRI is done to rule out metastasis of adrenal. On in-phase and out phase imaging (Figs. 1,2) showing a significant loss of signals within the mass on out of phase imaging suggestive of lipid rich adrenal adenoma. The signal intensity drops below signals of spleen.
