The aim of this study was to examine trends in physicians in diagnostic and pediatric radiology with subset analysis of female representation within these specialties in the United States between 2017 and 2024. We sought to assess changes in the proportion of radiologists, identify growth or decline patterns, and analyze potential factors contributing to the observed trends. Read More

We present a case of an 11-year-old male with history of pars planitis (intermediate uveitis) on monthly infliximab and weekly methotrexate. The patient developed diffuse lymphadenopathy, predominantly in the head and neck region, raising suspicion for malignancy. CT of the neck and chest demonstrated enlarged cervical, upper mediastinal , and bilateral axillary lymph nodes. PET/CT confirmed prominent FDG uptake in these lymph nodes. A lymph node biopsy of a parotid lymph node confirmed Epstein Barr virus-positive polymorphic lymphoproliferative disorder in the setting of immune deficiency/dysregulation. Follow up PET/CT 2 months later after discontinuation of immunosuppressive therapy demonstrated significant improvement in size and radiotracer uptake of the enlarged lymph nodes. However within this time frame, the patient’s uveitis worsened. The patient is being followed by ophthalmology to explore other localized treatment options including steroid eye drops and steroid implants. The majority of described findings in the radiology literature encompasses lymphoproliferative disorders in the setting of transplant (post-transplant lymphoproliferative disorder (PTLD)) or primary immunodeficiency. However, there is little in the way of lymphoproliferative disorders associated with immunosuppressive therapy. Most cases reported in the literature involve methotrexate use in adults with rheumatoid arthritis. Prior to 2022, this entity held a WHO classification entitled “other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OII-LPD)”. Following a 2022 WHO reclassification, both PTLD and OII-LPD are encompassed under the classification of “lymphoid proliferations and lymphomas associated with immune deficiency and dysregulation". Further research on imaging of OII-LPD would add to the existing literature and increase awareness of such an entity in the setting of immunosuppressive therapy. Read More

As more pediatric patients are infected with severe acute respiratory syndrome coronavirus 2 during the coronavirus disease 2019 (COVID-19) pandemic, more have been diagnosed with multisystemic inflammatory syndrome in children (MIS-C). Early research investigations into MIS-C show cardiac involvement presenting as elevated troponins, ventricular dysfunction, electrical conduction abnormalities, and pericardial effusions. MIS-C may result in myocardial perfusion defects visualized with nuclear medicine imaging and magnetic resonance imaging (MRI), however these perfusion defects on contrast enhanced computed tomography (CT) have not yet been described.

Pediatric abdominal trauma can be challenging and often necessitates rapid and accurate identification of injuries for optimal patient care. This study aimed to assess the potential workflow improvements in diagnostic accuracy achieved with semi-automated analysis of Dual Energy CT (DECT) image reconstruction in the setting of abdominal solid organ injury, as compared to conventional Multi-Detector CT (MDCT) images. The data sets from dual energy reconstructions have superior tissue differentiation and can be used to train a simple artificial intelligence (AI) program to recognize these patterns and expedite care.

Kagami-Ogata syndrome (KOS) is a rare and potentially underdiagnosed imprinting disorder caused by paternal uniparental disomy for chromosome 14 or microdeletions and epimutations involving differentially methylated regions (DMRs) at 14q32.2. Depending on phenotypic expression, KOS may mimic trisomy 18 and asphyxiating thoracic dysplasia. Therefore, awareness is essential for prenatal diagnosis. Coat hanger ribs as seen by x-rays have been reported as s pathognomonic sign but have not been reported prenatally. Herein we present images of the coat hanger ribs as seen by low-dose computerized tomography (CT) as well as detailed imaging of the multiple phenotypic features by ultrasound and MRI of KOS in two cases seen prenatally. Case 1: G1P0 singleton pregnancy had fetal echocardiogram at 25 weeks due to concern for congenital heart disease, thickened nuchal fold and thickened skin of the thoracic wall. The exam showed left superior vena cava draining to coronary sinus, dilated right atrium and right ventricle, total anomalous pulmonary venous return, and hydrops. Skin edema was redemonstrated by follow up US at 29 weeks. Fetal MRI and follow-up US at 32 weeks showed polyhydramnios, diffuse skin edema, prominent cheeks and frontal bossing by 3D US, mild shortening of the ulna and right clubfoot, and a bell-shaped thorax by MRI. Chromosomal microarray was positive for terminal deletion of 14q32.2, consistent with KOS. Coat hanger ribs were present on postnatal x-rays. The patient is G-tube and tracheostomy tube dependent, has global developmental delay, neuromuscular scoliosis, left hip subluxation, wrist contractures and planovalgus feet at the age of 2 ½ years. Case 2: G3P1, singleton pregnancy with negative non-invasive prenatal testing (NIPT). US performed at 29 weeks showed polyhydramnios, clenched hands, and bell-shaped small thorax. Multimodality fetal imagin (US, MRI and CT) at 32 weeks showed a narrowed elongated thorax by US and MRI but ribs were poorly visualized. Additional anomalies included polyhydramnios, rhizomelic bone shortening, clenched hands, and prominent cheeks by 3D US. Low-dose CT showed coat hanger ribs. Postnatal x-rays confirmed coat hanger ribs and other abnormalities. Postnatal genetic testing showed paternal uniparental disomy for chromosome 14, consistent with KOS. The patient has restrictive lung disease due to hypoplastic thoracic cage, hypotonia, scoliosis, developmental delay, and umbilical hernia at 13 months. Read More

Growth in our hospital has resulted in multiple new locations opening which has resulted in staffing by ultrasound technologists lesser experienced in appendicitis imaging. Likewise, our ordering providers have increased their push to reduce CT utilization. Our aim was to improve the appendix visualization frequency by 10% over 6 months to reduce exposure to ionizing radiation, reduce cost for families, lower risk to patients, reduce length of stay in the emergency department, and shorten the time to diagnosis.
