case_images: CT findings during hospitalization. . (A, B) Non-contrast CT on day 0 (admission) and contrast-enhanced CT on day 13, respectively. (A) There were no abnormal findings in the lung parenchyma except passive atelectasis in the dependent areas. No hepatomegaly or splenomegaly is observed. A round lesion adjacent to the spleen is identified as a left-sided renal cyst (arrow). (B) Widespread, poorly defined small nodules and ground-glass opacities are observed diffusely in both lungs. The liver and spleen exhibited no morphological abnormalities or enlargements. A left renal cyst is observed (arrow).. CT: computed tomography

case_images: HRCT revealed no abnormalities, excluding emphysema and passive atelectasis in the dependent areas, and there was no evidence of lymphadenopathy, hepatosplenomegaly, pleural effusion, or ascites (Figure 1A). While neither examination revealed findings suggestive of malignancy or abscesses, the repeated CT demonstrated new, diffuse, small nodular opacities in the lungs (Figure 1B).
case_images: Pathological findings of bone marrow aspirate. . (A) Granuloma formation with Langhans giant cells is observed (arrow). The bone marrow shows normal trilineage hematopoiesis. (B) Acid-fast bacilli are identified within the granuloma. Staining: (A) hematoxylin and eosin staining and (B) Ziehl-Neelsen staining. Scale bar: (A) 100 mum and (B) 50 mum.
