Myopericarditis is a rare disease of predominantly viral etiology but can also be caused by direct or indirect trauma (by contiguity). We present herein the case of a 76-year-old man that sought medical attention for 2-day central chest pain radiating to the scapula, fever, and dysphagia with solids and liquids. An electrocardiogram (Fig. 1) showed ST-segment elevation in the precordial leads. Laboratory test results reported CRP levels of 329.6mg/dl and high troponin levels of 1,695.8pg/mL (normal 0-20). The patient was admitted to the hospital due to suspicion of acute myopericarditis. A chest computed tomography (CT) scan (Figs. 2 and 3) revealed a 55×50mm calcified image located in the esophageal lumen that was dependent on the right esophageal wall, consistent with an epiphrenic diverticulum containing luminal material. Given those findings, the patient’s clinical worsening, and the absence of response to anti-inflammatory drugs, we decided to perform an esophagogastroscopy (Figs. 4A and B). An esophageal diverticulum was identified that contained a plum seed, a pill, and food remnants, all of which were sequentially extracted utilizing a snare. Decubitus lesions were also present in the intra-diverticular mucosa (Fig. 5). The myopericarditis was most likely produced mechanically, due to the fact that the myocardium and pericardium were affected by the transmural inflammation caused by the foreign bodies retained in the diverticulum (Figs. 2 and 3). After their extraction, the patient improved and was discharged 72h later.
