Sudden Death Due to Coronary Vasculitis: An Unexpected Autopsy Finding and Unusual Association With Thymic Hyperplasia

Abstract

A 43-year-old Asian woman was found unresponsive on the sidewalk, prompting a call to 911. Upon transportation to the hospital, no signs of trauma were evident, but her condition deteriorated, leading to her eventual passing. An autopsy revealed a complete occlusion of the right coronary artery due to segmental coronary artery vasculitis. Without details of the individual's social or medical history, the specific type of coronary vasculitis couldn't be determined. The internal examination also showed thymic hyperplasia of unknown origin. While there is no conclusive evidence, a potential link between thymic hyperplasia, immune dysregulation, and coronary artery vasculitis is discussed, considering the case and existing literature.
