When an AML has typical appearances there is essentially no differential. If atypical, especially when fat-poor other lesions to consider include:
- Retroperitoneal liposarcoma invading the kidney:
- Presence of a large vessel extending into the renal cortex suggestive of AML; liposarcoma is hypovascular
- Renal parenchymal defect at the site of tumour contact favours exophytic angiomyolipoma- claw sign
- Calcifications suggest liposarcoma
- Adrenal myelolipoma
- Renal cell carcinoma (RCC)
- may contain fat: lipid necrosis or osseous metaplasia
- Oncocytoma: may contain fat
- Wilms tumour: may contain fat
- Perirenal fat entrapment / renal junctional parenchymal defect
