Strangulated pericardial hernia presenting as a case of STEMI; when the disease misleads the physician: a very rare case report.

INTRODUCTION AND IMPORTANCE

The pericardial hernia is a rarely encountered clinical condition characterized by the herniation of the abdominal viscera into the pericardial cavity. Trauma precedes the development of these hernias in most cases, yet iatrogenic intervention and congenital defects are other potential causes.

CASE PRESENTATION

A male aged 60 years, with no history of previous trauma, presented with epigastric pain and was diagnosed with a case of STEMI. After the treatment, the patient continued to deteriorate and developed repeated vomiting. Surgical consultation was counseled which recommended a plain erect abdominal radiograph that revealed air-fluid levels. During surgery, the surgeon noticed a strangulated jejunum protruding into the pericardium, and the case was diagnosed as a pericardial hernia.

CLINICAL DISCUSSION

Pericardial hernias could be congenital or acquired and trauma is regarded as the commonest cause in adults. According to the history and clinical presentation the cause could be an old-forgotten trauma that has led to the small defect formation and protrusion of the jejunum. Trauma is regarded as the commonest cause; however, cases can pass unnoticed. The clinical presentation of this patient was initially related to acute coronary syndrome and was treated with primary coronary intervention, later a co-existing cause or probably the initiating cause was found to be a pericardial hernia.

CONCLUSION

The diagnosis of the case makes a significant challenge that requires a high index of suspicion due to the rarity of the condition, variable clinical presentation, and the delayed development of symptoms.
