Abstract
Hereditary leiomyomatosis and renal cell cancer (HLRCC) is caused by heterozygous germline variants in the fumarate hydratase (FH) gene and is associated with increased susceptibility to cutaneous leiomyomas, uterine leiomyomas, and renal cell carcinoma (RCC). HLRCC-associated RCC usually occurs in the middle age, with the median age being 40-44 years. This report describes a seven-year-old (84-month-old) male who developed a large right kidney tumor with multiple cystic lesions that contained enhanced solid components. There was no evidence of distant metastasis. The male patient underwent right nephrectomy and has been recovering well without metastasis or recurrence. Pathological examination revealed that tumor cells with relatively prominent nucleoli and surrounded by halos, were located in a limited area. Immunohistochemical staining was negative for FH. Whole-exome sequencing identified his germline variant in the FH gene and its loss of heterozygosity in the tumor. At nine years (114 months) of age, the male patient showed no recurrence of the tumor. This was the youngest-onset case of HLRCC-associated RCC to date. This report may affect the starting age for future RCC-surveillance programs for patients with HLRCC.

Abstract
Pediatric renal cystic diseases include a variety of hereditary or non-hereditary conditions. Numerous classifications exist and new data are continuously published. Ultrasound is the primary technique for evaluating kidneys in children: conventional and high-resolution US allows a detailed visualization of renal parenchyma and of number, size and location of the cysts, hence representing the most important diagnostic imaging technique for the first diagnosis and follow-up of these young patients. The purpose of this pictorial essay is to review the spectrum of renal cystic lesions in children from simple, complex or malignant single cysts to the several poly/multicystic kidney diseases.

Abstract
PURPOSE To compare dual-energy CT (DECT) iodine overlay images with renal mass protocol CT in the evaluation of polycystic kidneys with respect to reading time, diagnostic confidence, and detection of renal lesions that are not definitively benign. METHODS Following IRB approval, portal venous phase dual-source DECT scans performed between September 2013 and February 2016 from 55 patients (mean age 67 ± 15 years, 31 male, 24 female) with polycystic kidneys (4 or more cysts) were included. For each patient, two image sets were created: (1) DECT post-processed iodine overlay images and (2) simulated renal mass protocol CT images (virtual noncontrast and mixed images). Two radiologists independently retrospectively reviewed both sets at separate time points, evaluating for the presence of lesions that were not definitively benign (enhancing lesions or Bosniak IIF cysts), as well as reading times and Likert scale diagnostic confidence ratings (scaled 1-5) for the presence of non-benign lesions. Reading times were compared with a t test, diagnostic confidence with a McNemar test, and lesion number detection with Cohen's kappa test. RESULTS Iodine overlay images were read faster (mean 55 ± 26 s) than renal mass protocol (mean 105 ± 51 s) (p < 0.001). Readers assigned the highest diagnostic confidence rating in 64% using iodine overlay series, compared to 17% using renal mass protocol (p < 0.0001). The proportion of patients with recorded lesions was not significantly different between methods (p = 0.62). CONCLUSIONS DECT improves lesion assessment in polycystic kidneys by decreasing reading times and increasing diagnostic confidence, without affecting lesion detection rates.

Abstract
Objective: To report newly identified mutations in two families in China with cystic renal disease. Case presentations: Two fetuses were found by prenatal ultrasound to have symmetrically enlarged kidneys with increased echogenicity and cystic changes. We isolated fetal and parental genomic DNAs from umbilical cord blood and circulating leukocytes, performed next generation sequencing for mutations, followed by Sanger sequencing for confirmation. We discovered two new heterozygous mutations in PKHD1: c.2507_2515delTGAAGGAGG (p.Val836_Glu838del) in exon 24 among the fetus and father, as well as c.6840G>A (p.Trp2280*) in exon 42 among the fetus and mother. A mutation of c.2507_2515delTGAAGGAGG caused deletion of three amino acids. Two heterozygous mutations in AHI1, c.1304G>A (p.Arg435Gln), and c.3257A>G (p.Glu1086Gly) were identified in the second fetus, while the former was also found in the mother. The mutated locus in AHI1 is highly conserved among humans, dogs, mice, and monkeys. Conclusions: We report two newly identified mutations in PKHD1 and AHI1. An accurate genetic diagnosis is crucial for genetic counseling of parents with offspring carrying cystic renal disease.

Abstract
A number of inherited renal diseases present with renal cysts and often lead to end-stage renal disease. With recent advances in genetics, increasing number of genes and mutations have been associated with cystic renal diseases. Although genetic testing can provide a definite diagnosis, it is often reserved for equivocal cases or for ongoing investigational research. Therefore, imaging findings are essential in the routine diagnosis, follow-up, and detection of complications in patients with inherited cystic renal diseases. In this article, the most recent classification, genetic analysis, clinical presentations, and imaging findings of inherited cystic renal diseases will be discussed.

Abstract
Purpose To assess the efficacy of percutaneous unroofing in the treatment of simple renal cysts instead of laparoscopic decortication and open surgeries. Materials and Methods From November 2009 to October 2010 at our department, 11 patients with 12 simple cyst units were managed by percutaneous unroofing. All cysts were evaluated with ultrasonography and abdominal computed tomography. If there were no contraindications, cyst wall resection was performed. A standard transurethral resectoscope was used to resect the cyst wall, and the parenchymal portion of the cyst was subsequently cauterized. The drain was left in place for 2 days. Results At the 5-month follow-up, patients were asked about their symptoms and ultrasonography was performed. From 12 cyst units, 8 were completely resolved, 3 were reduced to less than 50%, and 1 was persistent to near its original size. Success was defined as a more than 50% reduction in cyst volume. Conclusions Simple renal cysts can be safely managed by percutaneous unroofing with a success rate of more than 90%. This technique can offer several advantages over open surgery, such as decreased length of hospital stay, improved convalescence, and reduced risk of complications. Percutaneous resection also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.
