FIG. 18.69 Renal Posttransplant Lymphoproliferative Disorder in Two Patients. Patient 1: (A) Sagittal sonogram shows iniltrative mass
(arrows) in renal hilum. (B) Six months later, the mass (arrowheads) has iniltrated into the renal cortex. (C) Correlative CT shows hilar mass iniltrating
into renal cortex. Patient 2: (D) Sagittal and (E) transverse sonograms show a hypoechoic to anechoic structure with low-level echoes (arrows) in
the renal hilum that could be interpreted as a complex cyst. (F) Contrast-enhanced MRI shows that this structure represents a solid mass (arrows).
