Imaging neuroblastoma in children

Crit Rev Comput Tomogr. 2003;44(1):47-61.

Abstract

Neuroblastoma is a common solid tumor of childhood that can involve the abdomen, thorax, pelvis, or the head and neck. The clinical manifestations are dependent on the widespread distribution of neural crest tissue and the length of the sympathetic chain involvement. Abdominal pain and hypertension may occur as a result of renal vasculature compression; respiratory distress may be evident in thoracic tumors; and Homer's syndrome or heterochromia of the iris may manifest from neuroblastoma of the head and neck. In addition, symptoms of cord compression and back pain may result from spinal cord compromise due to epidural invasion. Metastatic involvement of the liver, skin, periorbital regions, or bone may cause hepatomegaly, skin nodules, proptosis, or bone marrow failure, respectively. Clinical findings along with tumor metastasis may be studied by various imaging modalities to assess the nature and extent of the tumor. Diagnostic tests include plain radiography, ultrasonography, CT scanning, and MR imaging. Bone marrow studies, bone scans, and scintigraphy with 131I-metaiodobenzylmandelic may be utilized for metastatic evaluation. By using these imaging studies to detect the nature and behavior of neuroblastoma, early intervention may indeed improve patient survival.
