Key result
Surgical excision of a large hemorrhagic pericardial cyst mimicking acute coronary syndrome led to complete symptom relief and normalization of electrocardiogram findings.
Case Report (n=1)
A hemorrhagic pericardial cyst can present with intense chest pain and ECG changes mimicking acute coronary syndrome, highlighting the importance of multimodality imaging in the differential diagnosis of acute chest pain.

Consider hemorrhagic pericardial cyst in ACS mimics with multimodality imaging; single case leaves open generalizability of surgical excision.
Pericardial cysts are rare clinical entities mostly asymptomatic and detected incidentally. Albeit rare, many complications are reported and extend from cough and dyspnea to sudden cardiac death. The case presented herein is the first large and localized hemorrhagic pericardial cyst mimicking an acute coronary syndrome (ACS) with intense chest pain, precordial ST-segment elevation, and elevated troponin. Following thorough investigations, this cyst appeared to be associated with moderate pericardial effusion explaining myopericarditis as a cause of the findings listed. After surgical excision, the patient experienced relief of his symptoms, and Serial electrocardiograms (ECG) post-operative were normalized.

Ezzedine et al. (2023) conducted a case report in Pericardial Cyst Mimicking Acute Coronary Syndrome (n=1). Surgical excision was evaluated on Symptom relief and ECG normalization. Surgical excision of a large hemorrhagic pericardial cyst mimicking acute coronary syndrome led to complete symptom relief and normalization of electrocardiogram findings.
