Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen...

BACKGROUND: Early detection and interventions have enabled patients with sickle cell disease (SCD) to live well into adulthood. Consequently, the chronicity of SCD allows for the insidious manifestation of multisystem complications, including renal damage. Cystic renal lesions are commonly incidentally discovered on ultrasound and computerised tomography (CT) imaging of the abdomen. Most are benign simple cysts, however, difficulties may be encountered if infection, rupture, haemorrhage or cancerous changes develop...

The case of an elderly male diagnosed with a large iatrogenic pseudoaneurysm arising from the profunda femoris artery on ultrasound examination is presented. The immediate postoperative period was uneventful; however later he developed leg swelling and mild oozing at the incision site. In view of deranged renal function CT angiogram was not done and decision was made to treat the pseudoaneurysm with percutaneous thrombin injection. Almost complete thrombosis was achieved however a small residual portion remained patent near the neck...

A 10-year-old male castrated red kangaroo (Macropus rufus) presented with mandibular swelling. Examination findings included pitting edema with no dental disease evident on examination or radiographs. The results of blood work were moderate azotemia, hypoalbuminemia, and severely elevated urine protein:creatinine ratio (9.9). Radiographs showed an interstitial pattern of the caudal right lung, and an abdominal ultrasound demonstrated scant effusion. Symptomatic and empirical therapy with antibiotics, anti-inflammatory drugs, and an angiotensin-converting enzyme (ACE) inhibitor did not resolve clinical signs...

OBJECTIVES: The routine diagnostic method for assessment of renal graft dysfunction is Doppler ultrasound. However, contrast-enhanced ultrasound (CEUS) may provide more information about parenchymal flow and vascular status of kidney allografts. The aim of the study was to assess the effectiveness of CEUS in the immediate post-transplant period, focusing on acute vascular complications. A brief review of available literature and a report of our initial experience is made. MATERIAL AND METHODS: 15 kidney transplant (KT) cases with clinical suspicion of acute surgical complication were assessed with CEUS and conventional Doppler ultrasound (US)...

Herlyn-Werner-Wunderlich syndrome is an unusual congenital anomaly of the female genitourinary system, which is described as uterine didelphys with Obstructed Hemi-vagina and Ipsilateral Renal Anomaly (OHIRA), also known as OHVIRA syndrome. Typical symptoms are pelvic pain, tenderness, pelvic mass due to blood collection in the obstructed hemi-vagina and uterus, and dysmenorrhea that usually begins shortly after menarche. Clinical suspicion is very important for diagnosis and correct management avoids both short- and long-term complications...

Down syndrome (DS) is often associated with cardiac malformations, so that kidney damage is little known. The objective of this study was to present the diversity of renal abnormalities and their potential progression to chronic renal failure. Among congenital abnormalities of the kidney and urinary tract (CAKUT) abnormalities appear to be frequent: pyelectasis, megaureters, posterior urethra valves, as well as renal malformations such as renal hypoplasia, horseshoe kidney, or renal ectopia. Contributing factors to acute kidney failure have been described in patients with DS: bilateral lesions and minor renal injury, such as glomerular microcysts, tubular dilation, and immature glomeruli...

The incidence of nephrolithiasis continues to rise. Previously, we showed that a monogenic cause could be detected in 11.4% of individuals with adult-onset nephrolithiasis or nephrocalcinosis and in 16.7-20.8% of individuals with onset before 18 years of age, using gene panel sequencing of 30 genes known to cause nephrolithiasis/nephrocalcinosis. To overcome the limitations of panel sequencing, we utilized whole exome sequencing in 51 families, who presented before age 25 years with at least one renal stone or with a renal ultrasound finding of nephrocalcinosis to identify the underlying molecular genetic cause of disease...

Data on the progression of atherosclerosis in spondyloarthritis (SpA) are scarce, despite a high burden of cardiovascular diseases (CVD). The aim of this study was to identify the predictors of an accelerated subclinical atherosclerosis in patients with SpA. Study participants were 66 patients free of CVD classified according to ASAS criteria. The patients were evaluated at baseline and after 13.5 ± 3.6 months. Ultrasound measurements of carotid intima-media thickness (cIMT) and distensibility coefficient (cDC) were used to assess the extent of subclinical atherosclerosis...

The incidence of renal abscesses is not common. Patients usually have risk factors like diabetes mellitus or an underlying condition which predisposes to urinary tract infections. We report a case of a previously healthy young girl with multiple bilateral renal abscesses. Ultrasonography revealed multiple renal abscesses with a possible differential diagnosis of polycystic kidney disease with infected cysts. No renal calculi were seen. CT-scan of kidneys confirmed the diagnosis. Blood and urine cultures were repeatedly negative...

BACKGROUND: Trauma is the main cause of morbidity and mortality in the pediatric population. Blunt trauma to the abdomen accounts for the majority of abdominal injuries in children. Pancreatic injury, although uncommon (2 to 9%), is the fourth most common solid organ injury. Unlike other solid organ injuries, pancreatic trauma may be subtle and difficult to diagnose. Computed tomography currently is the imaging modality of choice. As the incidence of pancreatic injury in children sustaining blunt abdominal trauma is low, management remains a challenge...

BACKGROUND: Vascular complications in renal transplant patients are a well-known issue in post transplant patient care. If malfunctioning of the renal transplant is suspected to be caused by vascular complications an early diagnosis and therapy is required to maintain the renal transplant. Computed tomography (CT), digital substraction angiography (DSA) and radioisotope renography are the gold standard imaging modalities to diagnose vascular complications. OBJECTIVE: To analyse the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) in comparison to the standard imaging modalities CT, DSA and radioisotope renography in the diagnosis of vascular complications in renal transplant patients...
