A comparison of pulmonary embolism in pediatric and adult patients with acute COVID-19

Hodes, Aaron D; Villasana-Gomez, Geraldine; Traube, Leah; Kurian, Jessica; Liszewski, Mark C; Lazarus, Matthew S; Levin, Terry L; Blumfield, Einat
BACKGROUND:COVID-19 is associated with pulmonary embolism (PE) in adults. However, the rate of PE in pediatric patients with acute COVID-19 evaluated by CT pulmonary angiography (CTPA) has not been evaluated. OBJECTIVE:Determine PE rate in pediatric patients with acute COVID-19 and compare to adults. MATERIALS AND METHODS/METHODS:A retrospective review of CTPA studies, performed between March 2020 and January 2021 on pediatric patients with acute COVID-19, but not MIS-C, was performed. CTPAs performed on an adult cohort of acute COVID-19 patients during April 2020 were reviewed for comparison. Pediatric and chest radiologists independently reviewed CTPAs of pediatric and adult patients, respectively. RESULTS:Of the 355 acute COVID-19 pediatric patients treated during the study period, 14 (16.6 ± 4.8y, median-18.5y, 64% female) underwent CTPA. Of the 1868 acute COVID-19 adults treated during two weeks in April 2020, 50 (57.2 ± 17.0y, median-57.0y, 42% female) underwent CTPA. The PE rate was 14% in the pediatric group (2 patients) and 18% in the adult group (9 patients) (p = 1.0). Both pediatric patients with PE were obese, over 18y, and had asthma, diabetes mellitus, or hypertension. No child<18y with acute COVID-19 had PE. In the adult cohort, higher alanine-aminotransferase and D-dimer levels were associated with PE (p = 0.04 and p = 0.004, respectively). CONCLUSION/CONCLUSIONS:Despite similar PE rates in pediatric and adult patients, PE occurred in acute COVID-19 pediatric patients who were >18y, obese, and had at least 1 comorbidity. Children <18y with COVID-19 did not have PE.

Acute myocardial infarction on Nongated chest computed tomography [Case Report]

Salgado Guerrero, Maria; Cepeda De Jesus, Gabriela; Irfan, Wakil; Villasana Gomez, Geraldine; Arevalo, Ana B; Faillace, Robert
Contrast-enhanced chest computed tomography (CT) is not considered part of the evaluation of myocardial infarction. However, acute myocardial infarction has been detected on contrast-enhanced chest CT as areas of decreased myocardial enhancement in patients evaluated for other indications, such as pulmonary embolism and aortic dissection. We present a case of acute myocardial infarction on a nongated chest CT in a 67-year-old male who presented with atypical chest pain and initial nondiagnostic electrocardiogram. This case highlights that acute myocardial infarction may be detectable on contrast-enhanced CT. When evaluating contrast-enhanced chest CT's for other etiologies of chest pain, radiologists should look for potential myocardial perfusion abnormalities that can provide clues to the presence of myocardial infarction.
