Severe Calcific Chronic Constrictive Pericarditis as an Unexpected Cause of Death: An Autopsy Case

Chronic calcific constrictive pericarditis is a rare condition. It can cause severe morbidity and even mortality. The diagnosis may be difficult to establish due to its variable clinical signs. We report an autopsy case of a 54-year-old male with a past medical history of well treated hypertension, diabetes and dyspnea present of 2 weeks, who was discovered dead in his bed. The postmortem examination showed a large band of calcification of the pericardium with obliteration of the pericardial space. Both pericardium and epicardium were thickened with bread-and-butter appearance. Microscopic examination showed thickened pericadium which is formed by a fibrous paucicellular tissue containing extensive basophilic calcifications.
