A retrospective CT, MR, and clinical study was performed in 12 patients,
five children and seven adults, with histologically proved primary CNS
neuroblastoma. The CT and MR appearances of this neoplasia were more
variable than generally recognized. Although seven tumors were
predominantly intraparenchymal masses with calcification and cyst
formation, five were intra- or juxtaventricular. CT was preferable to
noncontrast MR both at initial diagnosis and follow-up for identification
of calcification, recurrent tumor at surgical sites, and leptomeningeal
disease. Noncontrast MR was useful primarily for localization of peri- and
intraventricular lesions. We conclude that primary CNS neuroblastoma has a
more variable radiographic appearance than is generally recognized, and
that an intra- or periventricular epicenter is common.
