Tuberculous constrictive pericarditis diagnosed by cardiac magnetic resonance imaging: A case report

Figure 1.. Pretreatment chest computed tomography (CT) imaging findings. (A) Axial lung window CT image shows bilateral pleural effusions, more prominent on the right side, with diffuse peribronchial thickening and patchy opacities in both lungs, indicative of inflammatory changes. (B) Axial mediastinal window CT image demonstrates significant pericardial thickening without evidence of pericardial calcification.

Figure 2.. Pretreatment cardiac magnetic resonance (CMR) imaging. (A) T2-weighted short-axis image shows pericardial thickening, with the thickest area measuring approximately 1.2 cm. (B, C) Late gadolinium enhancement (LGE) sequences in short-axis and 4-chamber views demonstrate pericardial enhancement, consistent with active pericarditis.

Figure 3.. Follow-up chest computed tomography (CT) after treatment. (A) Axial mediastinal window CT image at 3 months after treatment shows a marked reduction in pericardial thickening compared to baseline. (B) Axial mediastinal window CT image at 9 months shows near-complete resolution of pericardial thickening, with no signs of calcification or effusion.
