Unilateral Primary Adrenal Lymphoma: Uncommon Presentation of a Rare Disease Evaluated Using 18F-fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

Primary adrenal lymphoma (PAL) is a relatively rare disease entity with only fewer than 200 cases reported till date. PAL frequently presents with bilateral adrenal involvement and shows male preponderance. We here present a case of PAL in a 65-year-old female with a relatively uncommon unilateral adrenal involvement. The present case depicts that 18F-fluorodeoxyglucose positron emission tomography/computed tomography had decisive role in the treatment management of this patient suggesting its potential utility in the management of this rare disease.
