CT angiogram and spectral doppler US of bilateral renal artery stenosis in a patient with neurofibromatosis Type 1
3D reconstruction of a CT angiogram with contrast of the chest and abdomen (left) shows diffuse moderate narrowing of the mid aorta and marked narrowing of the origins of the renal arteries bilaterally. Spectral doppler US of the renal arteries (right) shows parvus tardis waveforms within them bilaterally.

The diagnosis was bilateral renal artery stenosis in a patient with neurofibromatosis Type 1.
