Polysplenia syndrome and sickle cell trait: extensive deep venous thrombosis from venous stasis and hypercoagulability.

Deep venous thrombosis is a hitherto under-recognized complication occurring in patients with polysplenia syndrome, despite the high prevalence of venous anomalies such as interrupted inferior vena cava (IVC) with azygos/hemiazygos continuation. Here we report the first case of concurrent polysplenia (as evidenced by interrupted IVC with azygos/hemiazygos continuation, multiple left-sided spleens, bowel malrotation with inverted mesenteric veins, preduodenal portal vein, and pancreatic hypoplasia/partial agenesis of the dorsal pancreas) and sickle cell trait, complicated by extensive deep venous thrombosis refractory to medical and interventional radiologic management.

Recent Innovations in Renal Vascular Imaging.

Noninvasive imaging of the vascular renal system is a common request in diagnostic radiology. Typical indications include suspected renovascular hypertension, vasculitis, neoplasm, vascular malformation, and structural diseases of the kidney. Profound knowledge of the renal anatomy, including vascular supply and variants, is mandatory for radiologists and allows for optimized protocolling and interpretation of imaging studies.

Bilateral Common Iliac Artery Endofibrosis in a Recreational Cyclist: Case Report and Review of the Literature.

External iliac artery endofibrosis is a rare medical condition typically encountered in young endurance athletes, mainly cyclists. Iliac endofibrosis usually develops in the external iliac artery and is rarely seen in the common iliac or in common femoral arteries. We describe a unique case of a patient who was not a professional or high-endurance cyclist.
