Computed tomography of adult neuroblastoma.

The computed tomographic (CT) findings in five adult patients with neuroblastoma and in one with ganglioneuroblastoma are presented. Four patients had abdominal and thoracic disease, one had abdominal disease only, and one had isolated chest involvement. The CT findings are nonspecific and may be confused with lymphoma. Nevertheless, multifocal presentation, particularly if it includes the posterior mediastinum and association with diffuse or focal bone involvement, when present, should suggest the diagnosis and lead to appropriate laboratory and histopathologic workup.
