Variation in the number of renal arteries (RAs) constitutes the most common and clinically important renal vascular variation. In this study, the authors describe a rare case of a 58-year-old male with eight RAs (bilateral quadruple) as revealed by routine multidetector computed tomography angiography. All the eight RAs originated from the abdominal aorta and penetrated the renal parenchyma at the level of renal sinus. The main RAs had the intraluminal diameter larger than the diameter of the additional renal arteries (AdRAs) at the origin. All the AdRAs had a greater length than the main RAs. These aspects are particularly important in planning microsurgical procedures. Clin. Anat. 25:973-976, 2012. © 2012 Wiley Periodicals, Inc. Copyright © 2012 Wiley Periodicals, Inc. Source

Renal ectopia also known as ectopic kidney is an embryological renal anomaly characterised by abnormal anatomical location of one or both of the kidneys. This can occur in various forms such as (1) crossed fused renal ectopia, (2) ectopic thoracic kidney and (3) pelvic kidneys. The lump kidney is one of the six variations of crossed fused ectopic kidney. Throughout life, the patient may remain asymptomatic, however, symptomatic patients may present with minor traumatic injuries due to the abnormal location or normal kidney pathologies. During normal embryological development, there is cephalic migration during which the kidneys ascend to their normal retroperitoneal location; therefore, an ectopic location is as a result of arrested migration. During this embryological development the kidney has multiple aorto-illiac branches, which degenerate when the kidney reaches its normal location. Here they develop new renal branches from the aorta and during an arrested ascent the ectopic kidney tends to retain some of the older aorto-iliac vessels. Hence, the arterial supply and the veineux drainage are grossly abnormal, reflecting the metanephric malascent and the primitive vascular arrangement. The collecting systems also present with important anatomical variations. We present an extremely rare case of right lump kidney with six renal arteries, two renal veins and two duplicated pelvicalyceal systems. © 2014, European Union. Source

We report an atypical case of a 53-year-old male with the presence of six renal arteries (RAs) (bilateral triple) found incidentally on multidetector computed tomography (MDCT) angiography, which was used to investigate peripheral vascular disease of the lower limbs. The distance between the extreme points of RAs origin from abdominal aorta (AA) was in right 4.42 cm, and in left 2.40 cm. The distance between the extreme points of penetration into the renal parenchyma was in right 2.01 cm, and in left 2.56 cm. On each side, the endoluminal diameter at the origin of the main RA (in right 0.54 cm, and in left 0.42 cm) was significantly larger in comparison with the other additional renal arteries (AdRAs) (in right 0.21–0.29 cm, in left 0.24–0.35 cm); however, the AdRAs were much longer (in right 7.42–10.82 cm, in left 5.90–6.85 cm) than the main RA (in right 6.21 cm, in left 5.73 cm). All the four AdRAs were hilar RAs. Knowledge of this anatomical variation should not be ignoring when planning the adequate interventional radiological and surgical procedure. © 2015 ROMANIAN ACADEMY PUBLISHING HOUSE.

The paper reports a quantitative analysis of the data provided by the apparent diffusion coefficient (ADC) values and relative cerebral blood volume (rCBV) in magnetic resonance imaging (MRI). The objective of this study was to establish if there was a connection between ADC values and rCBV, specifically in anaplastic gliomas (classified as WHO III grade) but with lower cellular malignancy at the surrounding area (WHO II grade). A number of 10 patients were examined with diffusion-weighted imaging (DWI) and perfusion-weighted imaging (PWI). The minimum, maximum and mean for ADC values and for rCBV have been calculated. As a result, we determined the ranges of ADC values and rCBV for mixed G II/III gliomas and we found a gradual increase of the rCBV while the ADC value decreases, most evident in the correlation of minimum ADC value and maximum relative CBV. In conclusion, significant information was obtained by correlating ADC values with rCBV. © 2015 IEEE. Source

We describe in this article a rare case of a 39-year-old male with an inferior phrenic arteries trunk (IPAaT) originating from a common stem with a superior additional left renal artery (SAdLRA) from the abdominal aorta as revealed by routine multidetector computed tomography angiography. The IPAaT with an endoluminal diameter at the origin of 2.8 mm had an upward path with a total length of 18.4 mm, forking to the right inferior phrenic artery and left inferior phrenic artery. These two arteries had an endoluminal diameter at the origin of 1.7 mm and 2.0 mm, respectively. The presence of the common stem of the IPAaT with a SAdLRA and the length of the IPAaT complicate selective chemoembolization of the liver parenchyma. Clin.
