Given the relative sensitivity of pediatric patients to radiation, the need to limit exposure to the region of interest is of the utmost importance in pediatric radiography. This study assesses the practice of acquiring pediatric chest radiographs at a community hospital in which the imaging contract was acquired by a radiology practice with subspecialty-certified pediatric radiologists. Pediatric radiologists in the new radiology practice saw a need for improved collimation of pediatric chest radiographs at the community hospital. Many radiographs exhibited poor collimation and included much of the abdomen. This study examines an initiative to measure and improve radiograph quality. Read More

Chronic cerebrovascular disease is common in pediatric sickle cell patients, and these children often require serial imaging to assess cerebral blood flow perfusion. ASL MRI has been shown to be an effective technique to assess cerebral blood flow, but the evaluation of perfusion reserve is also of value to ordering clinicians. This educational exhibit describes the use of the vasodilator acetazolamide to gauge potential changes in perfusion as determined by ASL MRI. The biochemical basis for cerebrovascular autoregulation and mechanism of acetazolamide are discussed. Read More

Propionic acidemia is a rare autosomal recessive disorder in which a genetic mutation results in the abnormal function of propionyl co-enzyme A (CoA) carboxylase, an enzyme involved in protein breakdown and lipid catabolsim. This results in the accumulation of metabolites which can have devastating neurologic consequences. The incidence in the United States has been reported as 1 in 100,000 births. The genetic and metabolic factors contributing to this disorder are discussed. Read More

Leptomeningeal melanocytosis is a rare proliferation of melanocytes in the arachnoid and pia mater that presents as diffuse leptomeningeal enhancement. Findings in a rare case of this disorder are discussed along with differential considerations and diagnostic implications. Read More

Teratomas uncommonly manifest in the gastrointestinal system, and most international literature cites the total number of gastric teratomas reported to be approximately 120. Of these, only 12-30 are of the immature variety. Reports of immature gastric teratoma in the United States are scant. Presented here are images from what appears to be the first known fetal MRI to demonstrate a gastric immature teratoma with follow-up radiographic, fluoroscopic, and CT imaging of the infant.

Umbilical catheters (UC) are ubiquitously utilized in neonatal intensive care units (NICU) during the early neonatal stage. Traditionally, these catheters are placed blindly, with the external length of the catheter being used to approximate catheter depth. This then requires subsequent radiographs to be obtained to assess for position, often in a sterile field, with considerable dead time. This exhibit will educate the viewer about the use of ultrasound guidance in the placement of these catheters. Read More

Molecular biology has come to the forefront of modern oncology. Knowledge of specific genetic mutations within tumors drives prognostic information and can guide therapy. Keeping up with new terminology in oncology can be difficult for pediatric radiologists who often host oncology conferences and present regularly at grand rounds. The purpose of this educational exhibit is to describe DICER1 syndrome and discuss its implications for pediatric radiology. Read More

Congenital Central Hypoventilation Syndrome (CCHS) is a rare disorder that can cause respiratory arrest during sleep. It is sometimes referred to as "Ondine's Curse" in reference to a fictional character who had to remember to breathe based on a spell cast by a jilted lover. The number of cases has been reported to be near 1,000. The purpose of this educational exhibit is to describe CCHS and emphasize its implications for pediatric radiology. Read More

Metronidazole is a commonly used and effective antimicrobial agent for gastrointestinal and genitourinary infections throughout the world. Common side effects of nausea, taste/appetite changes, and headache are well known, however, CNS side effects such as cerebellar dysfunction, dysarthria, and seizures have been reported even at therapeutic levels in rare instances. A previous review of the case literature concluded that resolution of symptoms was independent of age, however, evaluation of the pediatric population is limited. Read More
