Gibt es metastasierende Angiomyolipome

: An angiomyolipoma is now mostly diagnosed by sonography due to sonographically typical criteria, such as abundant echoes and clear delineation, or via CT, since it is a process rich in fat and hence hypodense. Laying bare by surgery will only be required in case of an atypical localisation or expansive tumour growth. Two case reports are presented with ipsilateral lymph node infiltration in multifocal angiomyolipoma and expansion of the tumour into the vena cava via the renal vein.
