Management of the congenital solitary kidney: consensus recommendations of the Italian Society of Pediatric Nephrology.

Pediatr Nephrol 2022 Jun 17. Epub 2022 Jun 17.

Pediatric Nephrology, Dialysis and Transplant Unit. Fondazione Ca' Granda IRCCS, Policlinico Di Milano, Milano, Italy.

Background: In recent years, several studies have been published on the prognosis of children with congenital solitary kidney (CSK), with controversial results, and a worldwide consensus on management and follow-up is lacking. In this consensus statement, the Italian Society of Pediatric Nephrology summarizes the current knowledge on CSK and presents recommendations for its management, including diagnostic approach, nutritional and lifestyle habits, and follow-up. We recommend that any antenatal suspicion/diagnosis of CSK be confirmed by neonatal ultrasound (US), avoiding the routine use of further imaging if no other anomalies of kidney/urinary tract are detected.

Zinner syndrome: a rare diagnosis in infancy.

BMJ Case Rep 2022 May 19;15(5). Epub 2022 May 19.

Radiodiagnosis, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India

We present a case of Zinner syndrome (ZS), where we were fortunate to diagnose a child with this rare syndrome immediately after birth. Gross hydronephrosis was observed during the prenatal period on ultrasound, and further imaging after birth confirmed the presence of a multicystic dysplastic kidney and seminal vesicle cyst. The majority of cases of ZS is asymptomatic; however, symptoms relating to urination, ejaculation or infertility may present later on in life and so regular follow-up is required to ensure interventions can be carried out if such symptoms do occur.

Radiol Case Rep 2022 May 10;17(5):1573-1578. Epub 2022 Mar 10.

Department of Radiodiagnosis, Atal Bihari Vajpayee Institute of Medical Sciences and Dr. Ram Manohar Lohia Hospital, New Delhi 110001, India.

Twin reversed arterial perfusion syndrome is a rare obstetric condition that occurs in monochorionic twin pregnancies, resulting in coexistence of a normal "pump" twin and an acardiac twin. The acardiac twin is dependent upon the normal twin to provide circulation by means of vascular anastomosis, thereby putting the pump fetus at risk of high output cardiac failure. Overall only 50% of pump twins survive. Read More

Ultrasound and alternative multimodality imaging of intra-abdominal and pelvic cystic masses in the newborn.

Ultrasound 2021 Nov 17;29(4):241-251. Epub 2021 Feb 17.

KK Women's and Children's Hospital Singapore, Kampong Java, Singapore.

Ultrasound is used commonly to detect and diagnose intra-abdominal and pelvic cystic masses in the newborn as it is easily available, relatively low cost, and non-invasive. The diagnosis can be made or narrowed down by determining the location, size, sonographic features, organ involvement, and internal vascularity. The differential diagnoses include hydronephrosis, multicystic dysplastic kidney, adrenal haemorrhage, cystic teratomas, ovarian cysts, enteric cysts, meconium cysts, and liver haemangiomas.

Presence of Cervical Vertebral Anomalies with Concomitant Non-Communicating Hydrocephalus and Multicystic Kidney in a Female Fetus: Where VACTERL-H Meets MURCS.

Fetal Pediatr Pathol 2021 Oct 23:1-10. Epub 2021 Oct 23.

Division of Prenatal Medicine, Department of Gynecology and Obstetrics, University Hospital of Schleswig-Holstein, Luebeck, Germany.

Background: Congenital multisystemic lesions with co-occurrence of non-random malformations, such as VACTERL-H or MURCS association, often pose serious threads to the newborn and still constitute an antenatal diagnostic dilemma.

Case Report: A malformed fetus with VACTERL-H association at 20 gestational weeks had a skin-covered neural tube defect (NTD) of the lower cervical spine, concomitant hydrocephalus, as well as unilateral multicystic dysplastic kidney and the suspicion of mullerian duct anomaly as potentially assigned to MURCS association.

Discussion/conclusion: We were able to demonstrate how well-defined, standardized volumetric reconstruction of diagnostic views displaying fetal pathology might aid early and precise diagnosis of multi-organ malformations. Read More
