Sudden death due to coronary artery dissection associated with fibromuscular dysplasia revealed by postmortem selective computed tomography coronary angiography: A case report

•Postmortem CT angiography revealed dissections of the coronary arteries.•Histopathology revealed vital dissection and signs of fibromuscular dysplasia.•Fibromuscular dysplasia was considered a risk factor for dissection.•This case shows novel utility of postmortem coronary artery angiography.

We present an autopsy case of sudden death due to coronary artery dissection associated with fibromuscular dysplasia (FMD) in a young female patient. Postmortem selective coronary artery computed tomography (CT) angiography revealed dissections of the left anterior descending and left circumflex arteries. These findings were confirmed by subsequent autopsy. Histopathological examination revealed coronary artery FMD, which is considered a risk factor for dissection.To the best of our knowledge, this is the first postmortem radiology–pathology correlation of coronary artery dissection associated with FMD.
