Abstract:

Coronary artery anomalies are a set of congenital conditions that may cause serious clinical problems and sudden deaths. We aim to present the case of a patient with a massive pulmonary embolism that coexisted with a malignant coursed coronary artery, which was detected on cardiac computed tomography. A 65-year-old female patient with complaints of chest pain, shortness of breath, diabetes mellitus, hypertension, and hyperlipidemia was referred to the radiology department on March 28th 2019. In cardiac computed tomography examination, only one coronary artery originating from the right coronary cusp was observed. The left main coronary artery arrived at its normal position after an interarterial course between the aorta and right ventricular outflow tract after the bifurcation. The patient had an embolism extending from the distal right main pulmonary artery to the lower and upper lobe segmental arteries. The patient’s informed consent was obtained. When pulmonary embolism is seen in interarterial course of the coronary artery in conjunction with the isolated coronary artery, it becomes a severe case. Coronary course anomalies can be detected on computed tomography angiography of pulmonary arteries and aorta. Therefore, radiologists should be careful to document these pathologies.
