After birth, ductus arteriosus forms ligamentum arteriosum and sometimes can be calcified. Ligamentum arteriosum calcification can be seen as subtle-punctate or coarse-linear between pulmonary artery and the aorta in the non-contrast computed tomography (CT) images, and between the pulmonary conus and the aortic knob in the chest radiography. In this study, we aim to esti-- mate the prevalence of ligamentum arteriosum calcification on non-contrast CT and chest radi-- ography in a pediatric population. Patients aged 0-18 years, who underwent non- contrast CT and chest radiography at Department of Radiology between March 1, 2020 and October 31, 2021 were evaluated retrospectively. It was examined wheth-- er there was ligamentum arteriosum calcifica-- tion in non-contrast CT and chest radiography. If there is calcification, it was recommended as subtle-punctate or coarse-linear, and information was documented by grouping the patients' age. If ligamentum arteriosum calcification was present, it was divided morphologically into two groups (subtle-punctate and coarse-linear) and classified according to the age groups. The research popu-- lation consisted of 1003 patients. Non-contrast CT revealed calcification in 25.5% of patients (n=256). 11.3% of patients had subtle-punctate calcification, and 14.3% had coarse-linear calci-- fication. Radiography had a 1.7% (n:17) detection rate for calcification. Ligamentum arteriosum cal-- cification is a common finding in all age groups in the pediatric population. When reporting pe-- diatric CT studies, radiologists should be able to distinguish ligamentum arteriosum calcification from other pathological and anatomical conditions and accept it as a normal finding in order to avoid unnecessary further investigations.
