The patient had no clinical symptoms at the time. Laboratory values were significant for an elevated urine homovanillic acid (HVA)/creatinine ratio of 361, and a normal urine vanillylmandelic acid (VMA)/creatinine ratio. Radiography (Figure 1), ultrasonography (Figure 2), computed tomography (CT) (Figure 3), and magnetic resonance (MR) imaging (Figure 4) were performed.Thursday, 10 Feb 2005 16:43:42 GMT
