Solitary splenic tuberculosis: A case report

Figure 1 Abdominal computed tomography of a large circular lesion in the spleen. A: Plain computed tomography (CT) showed a large circular lesion of mixed density (4.4 cm × 5.5 cm) in the spleen, and the CT value was 19-25 HU; B: Contrast-enhanced CT indicated the lesion and the CT value was 36 HU; C: Portal phase CT showed the lesion and the CT value was 48 HU. There were small patches of low-density liquefaction necrosis in the splenic parenchyma shown in (B) and (C).

Figure 2 Pathological analysis of the splenic lesion. A-C: Splenic tuberculosis pathological lesions including (A) granuloma (× 40), (B) multinucleate giant cells (× 40) and (C) acid-fast bacilli (× 40) were identified by hematoxylin and eosin staining and acid-fast staining.
