[Olfactory neuroblastoma--tumor entity or complex clinical picture?].

Clinical and radiological findings in seven cases of olfactory neuroblastoma are reviewed and discussed in the light of the international literature. The report provides further evidence of difficulties related to the predictability of the condition's clinical course, diagnosis, and therapeutic consequences. Moreover, the lack of uniform CCT and NMR features indicates that the discussion about the genesis, the biological action, the terminology, and therapy of these tumors has not yet reached a conclusion.
