case_images: A multiseptated thin-walled fluid collection was present in the hilum of the transplanted kidney which was separate from the transplant collecting system (Figure 1(a)). Magnetic resonance imaging (MRI) of the transplant kidney was performed and revealed a nonenhancing peripelvic multiseptated fluid intensity collection centered in the renal hilum, encasing the hilar vasculature and insinuating between but separate from the collecting system without vascular displacement or hydronephrosis (Figures 1(b) and 2).
