[The abdominal neuroblastoma].

Diagnosis of abdominal neuroblastoma by imaging techniques is demanding, and in most cases several complementary modalities are needed for correct staging. Ultrasonography is performed first, followed by contrast CT and/or MRI. Both skeletal and specific MIBG scintigraphy are essential in most cases. This applies not only for the primary diagnosis but also for monitoring the response to therapy and for picking up recurrent disease.
