Body
was changed:
Cardiac tuberculosisrefers to the infection of the cardiac musculature withMycobacterium tuberculosis tuberculosis. It is a rare entity but known to occur.
Pathology
Generally associated with and occurring as a complication of mediastinal and pulmonary tuberculosis.
Pericardial and myocardial involvement is known. Endocardial spread may occur from myocardium. Modes of spread to the myocardium are via lymphatics from mediastinal nodes, directly from the pericardium, or via a hematogenous route.
Radiographic features
Plain filmradiograph
- acute stage: no findings in heart; active lung infection may be present
- chronic stage: pericardial calcification
CT
- pericardial effusion (mild)
- pericardial thickening
- pericardial calcification (chronic stage)
Cardiac MRI
- T1: nodular lesion which appear isointense to slightly hyperintense
- T2: isointense
- C+ Gd: mild heterogeneous enhancement
Treatment and prognosis
Patients generally respond well to antitubercular therapy. Clinical examination, known primary pulmonary infection and follow-up examinations will help confirm the diagnosis.
Differential diagnosis
Imaging differential considerations include
- cardiac metastasis
- cardiac sarcoma
- cardiac lymphoma
