Abstract

A 52-year-old healthy woman with a congenital solitary right kidney
presented with an incidentally found pararenal mass. Computed
tomography and magnetic resonance imaging revealed an exophytic
mass in the right kidney consistent with an angiomyolipoma and an
additional enhancing pararenal mass that contained fatty elements.
Differential diagnosis of the mass included liposarcoma and angiomyolipoma.
Upon exploration, the exophytic angiomyolipoma was
found to be contiguous with the pararenal mass via an isthmus of
fatty tissue. Frozen sections were taken from both masses which confirmed
that both were angiomyolipoma. This is the first case reported
in the literature wherein an angiomyolipoma extended extrarenally
and formed a significantly larger pararenal mass.
