[Computer tomography of esthesioneuroblastoma]

Aesthesioneuroblastomas are rare malignant nasal tumours of neural origin. Clinical symptoms depend upon the extent of the lesion. Five cases of tomography visualised the tumours as non-homogeneous soft tissue masses in the nasal cavity and the ethmoid cells with a varying infiltration of the adjacent paranasal sinuses. Radical surgery and radiation therapy are recommended. CT should be an integral part of annual follow-up studies.
