  • Title: Epinephrine enhanced renal angiography in the diagnosis of hamartoma (angiomyolipoma): a reevaluation.
    Author: Jander HP, Tonkin IL.
    Journal: Radiology; 1979 Jul; 132(1):61-6. PubMed ID: 451220.
    Abstract:
    The vlue of epinephrine enhanced angiography in the preoperative distinction of isolated hamartoma (angiomyolipoma without stigma of tuberous sclerosis) from hypernephroma has been largely discounted in the past. The authors performed this procedure in 6 patients (4 with isolated hamartoma and 2 with tuberous sclerosis complex). Vasoconstriction of the tumor vessels in the isolated group suggested the benign nature of the hypervascular mass in all cases. Vasoconstriction stronger than that of normal parenchymal vessels suggested the diagnosis of isolated renal angiomyolipoma. This form of pharmacoangiography should be part of the routine preoperative workup of all solid renal masses.
