We present two separate cases of young male patients with congenital kidney anomalies (horseshoe and crossed fused renal ectopia) identified following blunt abdominal trauma. Despite being rare, ectopic and fusion anomalies of the kidneys are occasionally noted in a trauma patient during imaging or upon exploration of the abdomen. Incidental renal findings may influence the management of traumatic injuries to preserve and protect the patient's renal function. Renal anomalies may be asymptomatic or present with hematuria, flank or abdominal pain, hypotension, or shock, even following minor blunt trauma or low velocity impact...

A 58-year-old paraplegic patient was prescribed F-FDG for persistent inflammatory syndrome after aortic surgery for dissection. The examination was performed on a Siemens mCT Flow PET/CT and shows a moderate prostate uptake, related to prostatitis on self-catheterization and a focal renal cortical hypermetabolism of the left medial midpole of a horseshoe kidney, which corresponds to renal parenchyma on the CT, and suggests pyelonephritis, confirmed by Tc-DMSA SPECT/CT.

Primary extraskeletal osteosarcoma (EOS) is an extremely rare malignancy. In this report, the clinical course of a 32-year-old man presenting with proptoses is described. Medical history included Hirschsprung disease (HD), horseshoe kidney, azoospermia, and vertebral anomalies. Imaging of the orbit showed an oval, well-defined heterogeneous mass adjacent to the lateral wall of the orbit. The patient underwent a lateral orbitotomy and complete excision of the mass. The mass was not attached to the bone. Histopathologic and immunohistochemical examination confirmed the diagnosis of an EOS...

INTRODUCTION: Horseshoe kidney occurs in 1 per 400-800 live births and are more frequently observed in males (M:F 2:1). Ureteropelvic junction obstruction (UPJO) is commonly associated with horseshoe kidneys. The variable blood supply, presence of the isthmus and high insertion of the ureter contribute to this problem. CASE REPORT: An asymptomatic 6 year-old boy presented with antenatal hydronephrosis. Ultrasonography and CT scan demonstrated left UPJO associated with a horseshoe kidney...

We present a case of UPJO associated with an incompletely duplicated collecting system in a horseshoe kidney that was successfully treated by laparoscopic pyeloplasty with concomitant pyelolithotomy. A 53-year-old man had three urological anomalies and urolithiasis. We performed a pyeloplasty and pyelolithotomy using a fully intracorporeal technique. Clinical and radiographic evaluation confirmed complete resolution of the patient's condition. To our knowledge, there have been no reported cases of UPJO in an incompletely duplicated collecting system with a horseshoe kidney in the same patient...

Congenital renal malformations are the most common congenital malformations in humans, the most common being horseshoe kidney with joined lower poles present in up to 0.25% of general population. To the contrary renal fusions with ectopia are amongst the rare malformations affecting 1 in 2000 examined cadavers. Males are affected slightly more often then females (3:2), left to right crosses being more frequent. The value of early diagnosis of asymptomatic renal malformation is uncertain, except when other abnormalities might point to them and they can affect the clinical management strategy (severe ear deformity with facial malformation, gynecological abnormalities)...

INTRODUCTION: Acute arterial thromboembolism to the renal arteries can be treated promptly by local thrombolysis, conventional surgical thrombectomy, or by anticoagulation. METHODS: We report a patient who presented with acute loin pain as a result of atrial fibrillation related thrombo-embolism to right renal artery supplying his horseshoe kidney. He was already on warfarin treatment with INR of 1.7 and had acute bleeding from malignant peptic ulcer disease, so thrombolysis was contraindicated...

Horseshoe kidneys are a common, yet enigmatic, renal malformation. This review critically appraised the literature surrounding the embryology, etiology and clinical anatomy of horseshoe kidneys. The systematic literature search produced 104 articles, and 56 primary and further secondary references. There were several etiological theories regarding horseshoe kidneys. The established view was that during ascent, the kidneys come into close apposition as they pass through an arterial fork. Another possible mechanism related to lateral flexion of the trunk or rotation of the caudal embryo; the association of asymmetrical horseshoe kidneys with a number of vertebral conditions supported this hypothesis...
