ABSTRACT
A left main coronary artery (LMCA) stenosis due to extrinsic compression by mediastinal tumor is a rare finding. In this case reports, we present a 63-year-old woman, who was transferred to the emergency department with chief complains of persistent chest and back pain. An electrocardiogram revealed diffuse ST-segment depression (elevation in lead aVR). Contrast-enhanced computed tomography (CT) showed a huge cystic mass above the left atrium. After the CT examination, she was temporarily in shock. Compression of the LMCA was evident on the CT angiography and a diagnosis of acute myocardial infarction due to compression of the LMCA by a tumor was made. An emergent resection of the tumor was performed. Histopathological assessment of the resected cyst revealed that it was a schwannoma. She made an uneventful postoperative recovery. A follow-up 3-dimensional CT scan performed after the operation confirmed no evidence of LMCA compression.
