Overview

Angiomyolipoma must be differentiated from retroperitoneal liposarcoma, adrenal myelolipoma, and renal cell carcinoma.[1][2]

Differentiating Angiomyolipoma from other Diseases

Angiomyolipoma must be differentiated from the following:[1][2]

Differential diagnosis Characteristic features of the differential diagnosis
Retroperitoneal liposarcoma
  • Presence of a large vessel extending into the renal cortex suggestive of angiomyolipoma; liposarcoma is hypovascular
  • Renal parenchymal defect at the site of tumour contact favurs exophytic angiomyolipoma- claw sign
  • Calcifications suggest liposarcoma

Renal cell carcinoma
  • May contain fat
  • Lipid necrosis
  • Osseous metaplasia
Oncocytoma
  • May contain fat
Wilm's tumor
  • May contain fat
Retroperitoneal sarcoma
Renal cell carcinoma
  • Sarcomatoid differentiation
Renal leiomyoma
  • Very rare
  • Desmin +ve
  • HMB-45 -ve
Perirenal fat entrapment
  • Renal junctional parenchymal defect
Adrenal myelolipoma
  • Fat in renal parenchyma
