CT features that have been considered characteristic of (but not pathognomonic of) XGP (especially

in the diffuse form) are renal enlargement, strands in the perinephric fat, thickening of the Gerota fascia, and thick enhancing septa in the hypodense areas of the renal parenchyma. Round or egg-shaped areas of water density representing dilated calyces and abscess cavities with pus and debris in diffuse XGP may be described as the “bear paw sign”.5 CT usually depicts focal XGP as a clearly or poorly defined localized intrarenal mass with fluid-like attenuation. In our case, the radiologic examinations did not assist with the diagnosis; all of the pathognomonic aspects were absent, and all of the images indicated a complex cyst. We assume that the XGP was initially triggered in the middle third of the selleck kidney, creating the conditions for cyst formation, and, later, the inflammation Navitoclax cell line involved the entire renal parenchyma. Our case is unusual in its presentation; the patient had no history of kidney stones, and symptoms were absent or scarcely meaningful to suspect inflammation of the kidney. The intraoperative histologic examination identified the condition and enabled appropriate treatment. Our experience suggests the opportunity of a simple intraoperative histological examination in all cases of complex

cyst, otherwise the risk would be an under-treatment. The authors thank Editage, which provided language help. “
“Renal vein thrombosis (RVT) is the most common vascular condition in the newborn kidney. Factors predisposing a neonate to RVT include prematurity, dehydration, sepsis, birth asphyxia, shock, maternal diabetes, polycythaemia, cyanotic congenital

heart disease, and the presence ADP ribosylation factor of indwelling umbilical venous catheters.1 Possible mechanisms include reduced renal blood flow, hyperosmolality, hypercoagulability, and increased blood viscosity. RVT typically presents with a flank mass, hematuria, hypertension, and renal failure. These signs are frequently masked in a sick neonate. Neonates with RVT have significant morbidity, particularly hypertension and renal failure. Therefore, the prognosis depends on the time of diagnosis. The patient was a 1730-g male baby, born at 31 weeks gestation to a 37-year-old mother by cesarean section because of placenta previa with maternal bleeding and fetal distress. Initial chest radiograph showed respiratory distress syndrome. The baby required 1 dose of surfactant and 2 days of ventilation support. Umbilical venous catheterization was set for administration of intravenous fluids, nutrition, and medication. A sepsis episode happened on day 6 of life. Blood culture was positive for Escherichia coli and Acinetobacter baumannii. After 4 days of amikacin treatment, the baby stabilized.
