Tuberculous calcific constrictive pericarditis in an adult female with a past history of abdominal tuberculosis.

Tuberculous pericarditis, one of the rarer extrapulmonary manifestations of tuberculosis, remains a challenge in endemic countries such as India. As the clinical presentation of tuberculous pericarditis is highly variable, the diagnosis is often missed, delayed, or incorrectly diagnosed. Constrictive pericarditis (CP) is one of tuberculous pericarditis's most serious and advanced sequelae. Several invasive and non-invasive diagnostic modalities are crucial to address the challenges of confirming the diagnosis of CP in suspected cases. This study reports the case of an Indian adult female with a past history of previously treated abdominal tuberculosis diagnosed anew with tuberculous calcific constrictive pericarditis.
