Article Title: Duplex collecting system in a pelvic kidney - an unusual combination
Figure Lengend Snippet: 28-year-old woman with duplex collecting system in a pelvic kidney. Findings: CT-Angiography VR anterior view (A), CT-Angiography VR posterior view (B), MR-Angiography coronal MIP (C) and CT-Angiography coronal MIP (D) images demonstrate a left pelvic kidney, dysmorphic and malrotated, with deep lobes, altered hilar anatomy and complex vascularization. The main renal artery - that arises from the aorta, at the bifurcation, in the middle seat - is seen for a short tract (full arrowhead), as it moves to the posterior surface of the kidney and descends to the middle third. A branch, originating from the main artery, penetrates into the parenchyma at the upper pole (long arrow). An accessory renal artery (short arrow) arises from the right common iliac artery, just below the bifurcation, on the medial side and supplies the lower pole. Two renal veins, that originate from upper renal hilum, form a common trunk (empty arrows) which drains into the inferior vena cava (IVC). Another independent vein is recognizable at the lower hilum (empty arrowhead), draining in the right common iliac vein. Technique: Scan acquired in the angiographic phase on Aquilion 64, Toshiba Medical System CT scanner (Tokyo, Japan). The voltage was set at 100 kV, with an automatic mA modulation between 80 and 440 mA and a standard deviation (SD) value of 15.; beam collimation 64 × 0.5 mm, gantry rotation time 0.5 s, pitch 0.828. 110 cc Iobitridol 350 mgI/mL intravenous contrast administered at 3.5 mL per second. MR-Angiography sequence acquired on Avanto, Siemens Medical Solutions, 1.5 T (Forchheim, Germany) Spoiled Gradient Echo (TR 2.94ms TE 1.06ms) slice thickness 1.10mm GAP 0. 7.0 mL Gadobutrol 1.0 mmol/mL contrast injected at 3.0 mL per second.
