Figure 11a. Visceral fungal infection. (a) High-resolution US image obtained with a linear-array transducer shows a hypoechoic splenic nodule in an 8-year-old girl 6 weeks after bone marrow transplantation for acute lymphoid leukemia. (b) Contrast material–enhanced CT image shows multiple lesions in the kidneys, liver, and spleen in a 7-year-old boy 5 days after bone marrow transplantation for acute lymphoid leukemia. All the lesions were believed to have been caused by the same fungus.
