Computed tomography (CT), abdominal ultrasonography (Fig. 1a) and magnetic resonance imaging (MRI) (Fig. 1b) revealed a solid mass 39 x 34 x 38 mm in size in the right abdominal cavity. Within the same area, isotope imaging revealed a hot spot of radiolabeled [123I] m-iodobenzylguanidine (Fig. 1c). We therefore performed tumorectomy after careful blood pressure control using alpha blockers (Fig. 1d).
