Chronic renal impairment due to sustained hemolysis.. (A) Hemosiderin detected in the patient's urine with Berlin blue stain. (B) T2-weighted magnetic resonance imaging revealing hypo intensity, indicating hemosiderin deposits bilaterally in both renal cortices (shown by yellow arrows).

Table 1), and T2-weighted magnetic resonance imaging identified a hypointensity indicating hemosiderin deposits bilaterally in both renal cortices (Fig. 1B). The percentage of CD55 and CD59 defected RBCs was 32.2% in flow cytometry, suggesting that the PNH clone size had not changed over six years, and the clone type was type III.
