	The disease presents unique medical and legal challenges. Medically, the nonspecific cardiac symptoms it produces — chest pain, shortness of breath, pericardial effusion — lead to frequent misdiagnosis and diagnostic delays, with historically '''more than 75% of cases discovered only at autopsy''' (now declining to ~13–15% in modern series). Legally, the weaker and more controversial relationship between asbestos exposure and pericardial mesothelioma creates additional evidentiary complexities for patients seeking compensation.

	The weak asbestos association has prompted investigation of alternative risk factors. Prior radiation therapy for other cancers has been linked to rare mesothelioma development in some case reports. Erionite, a naturally occurring fibrous zeolite mineral with physical properties similar to asbestos, is an established mesothelioma carcinogen that could theoretically affect the pericardium. Germline mutations in the BAP1 tumor suppressor gene are well-characterized predisposing factors for mesothelioma at all anatomic sites, and one pericardial case was found to harbor a pathogenic BRCA1 germline mutation, suggesting that inherited DNA damage response pathway deficiencies may contribute independently of environmental exposures. The SV40 virus has been historically proposed but remains unconfirmed, and a substantial proportion of cases have no identifiable risk factor whatsoever.<ref name="frontiers-cardiac" /><ref name="penn-medicine~~" /><ref name="lungcancercenter~~" /><ref name="schoenfeld" />		The weak asbestos association has prompted investigation of alternative risk factors.
