Hepatoblastoma is the most common primary hepatic tumor in young children and its radiological findings have been well described. We report ultrasound and computer tomography findings in a case of hepatoblastoma diffusely involving the entire liver and presenting as inhomogeneity and numerous cystic lesions in the hepatic parenchyma.

The metallic stent provides good palliative drainage, and the percutaneous insertion of metallic stents is well tolerated by the patients. The procedure is simple and safe to use and can be executed in one stage. The one-stage procedure, compared to the 2-stage procedure, may reduce hospital stays.

Background: Transplant Renal Artery Stenosis (TRAS) is a well-known vascular complication after a kidney transplant. It is associated with premature renal failure, uncontrolled hypertension, and allograft loss. However, Proximal Iliac Artery Stenosis to a Kidney Transplant (Prox-TRAS) is an uncommon cause of vascular graft complication leading to acute renal failure and refractory hypertension with a less incidence around and only a few cases reports have been described in the medical literature. Methods: We reviewed the medical record of kidney transplant recipients of the General Hospital of Ciudad Real, Spain, from March 2008 to March 2019. We identified all cases (260) with the diagnosis of renal vascular hypertension by imaging studies. Of those 260 renal vascular stenoses, five (5) were diagnosed with proximal iliac artery stenosis through Angio-CT and arteriography. We performed an analysis of clinical parameters and evolution. Results: Prox-TRAS was diagnosed in 5 of the 260 patients who presented acute or progressive allograft dysfunction with refractory hypertension, with an incidence rate of 1.4%. In 4 of them (1.1%), we had to resort to another imaging test, angio-CT, arteriography, as the echo-doppler was unable to identify the abnormalities. Hypertension was a constant finding along with impaired renal function (100%); with respect to Prox-TRAS, its onset was later (12 -60 months) after transplantation. An increase in TA (140 ± 10 and 80.7 ± 7 to 160 ± 18 and 85 ± 7 mmHg, p-0.009) was observed. There was an increase in the use of hypotensive drugs (2.1 ± 1.1 and 4.3 ± 1, p-0.003).
