The Scintigraphic Drooping Lily Sign.

The "drooping lily" sign is identified on intravenous urography or voiding cystourethrography in patients with a duplicated renal collecting system and refers to inferolateral displacement of a functioning lower pole moiety by an obstructed upper pole collecting system. In this case, a 2-month-old girl with a prenatal diagnosis of hydronephrosis was found to have a "scintigraphic drooping lily" sign on Tc-dimercaptosuccinic acid renal scan. Evaluation with ultrasound and voiding cystourethrography confirmed a duplicated collecting system and obstructed upper pole moiety.

Novel Contrast-Enhanced Ultrasound Evaluation in Neonatal Hypoxic Ischemic Injury: Clinical Application and Future Directions.

Sensitive, specific, and safe bedside evaluation of brain perfusion is key to the early diagnosis, treatment, and improved survival of neonates with hypoxic ischemic injury. Contrast-enhanced ultrasound (US) imaging is a novel imaging technique in which intravenously injected gas-filled microbubbles generate enhanced US echoes from an acoustic impedance mismatch. This article describes contrast-enhanced US imaging in 2 neonates with hypoxic ischemic injury and future directions on developing quantitative contrast-enhanced US techniques for improved characterization of perfusion abnormalities.

Diagnosis of rare association of orthotopic multicystic dysplasia with crossed fused renal ectopia.

Orthotopic multicystic dysplastic kidney with crossed fused ectopia is a rare congenital anomaly. This congenital anomaly may give an appearance of a solitary kidney morphology during the initial imaging evaluation. A solitary kidney should be carefully evaluated for the presence of duplication, horseshoe configuration, or crossed renal ectopy.

Imaging of neonatal child abuse with an emphasis on abusive head trauma.

Child abuse and neglect is a serious clinical and socioeconomic problem that is sometimes underestimated. One of the most devastating forms is abusive head trauma. This review addresses the radiological workup in cases of suspected child abuse.

Low dose, oral epsilon aminocaproic acid for renal papillary necrosis and massive hemorrhage in hemoglobin SC disease.

Renal papillary necrosis in sickling hemoglobinopathies can lead to significant complications, including hemorrhage, obstruction, and infection. Despite its frequency, there are limited therapies for protracted hemorrhage. In the past, massive hemorrhage was managed with nephrectomy.
