Mesenteric lymphatic malformations are rare intra abdominal masses. Large mesenteric malformations can present soon after birth secondary to abdominal distention or failure to thrive. However, they can also remain clinically inapparent throughout childhood. In this series, three patients, ranging in age from 8 to 16 years, present with acute or acute on chronic abdominal pain. Subsequent imaging studies demonstrated macrocystic, mesenteric lymphatic malformations. These malformations may become painful in the setting of hemorrhage or superimposed infection. As this condition is likely not at the forefront of the clinician's mind, it is incumbent upon the radiologist to recognize the imaging findings. This case study will present a multimodality approach to the diagnosis of macrocystic, mesenteric lymphatic malformations. Read More

In an effort to improve communication of important radiology findings, we designed and deployed a unique comprehensive radiology report categorization (RADCAT) system that organizes results by acuity and need for radiology follow-up. The goal of our study is to outline and compare the distribution of RADCAT pediatric imaging reports from three different clinical settings. Read More

Congenital pulmonary airway malformations (CPAM), bronchopulmonary sequestrations (BPS), and hybrid lesions are the most common congenital lung lesions. They are primarily diagnosed prenatally via ultrasound and further characterized by MRI. While most affected neonates are asymptomatic at birth, some may experience varying severities of respiratory distress requiring intervention. We seek to develop a prognostic model for prediction of post-natal outcomes in patients with congenital lung lesions using fetal MRI calculated observed to expected normal lung volume (O/E NLV).

Rapid, non-contrast MRI has been reported as accurate for diagnosing acute appendicitis at specialized pediatric hospitals, but there remains a dearth of evidence-based, MRI-specific criteria upon which the diagnosis should be established. To our knowledge, our study comprises the largest study with the most independent readers of MRI-specific diagnostic criteria for pediatric appendicitis reported to date. Read More

Children undergoing hematopoietic stem cell transplantation (HSCT) are at high risk for infectious and non-infectious complications after transplant. While computed tomography (CT) is commonly used to identify asymptomatic infections or other abnormalities before transplant, there are limited data to support routine pre-transplant imaging with CT. We aimed to investigate the frequency of CT findings of infection, air trapping, or other unexpected abnormalities pre-HSCT. Read More
