Abstract:
Primary adrenal liposarcoma is very rare, accounting for only 0.2% of primary adrenal tumors. Primary bilateral adrenal liposarcoma is even rarer. We describe FDG PET/CT findings in a case of primary bilateral adrenal dedifferentiated liposarcoma. The bilateral adrenal tumors showed intense FDG uptake with SUV max of 32 and 44 for the right and left adrenal tumors, respectively. This case indicates that dedifferentiated liposarcoma should be included in the differential diagnosis of FDG-avid bilateral adrenal lesions, including adrenocortical carcinoma, pheochromocytoma, lymphoma, metastasis, and infection.
