[Computed tomographic diagnosis and differential diagnosis of malignant paranasal sinus tumors].
The CT appearances of malignant tumours of the paranasal sinuses are illustrated on the basis of 15 patients, and the differential diagnosis discussed. Malignant soft tissue tumours in the paranasal sinuses are characterised on CT by their non-homogeneous structure; they may destroy the bony margins of the sinus and infiltrate neighbouring regions in certain preferred directions, and they may enhance following the administration of contrast. Precise definition of the malignant tumour by CT permits their exact staging, may help to determine therapy and is valuable for serial observation. It remains to be seen, however, whether the improved radiological diagnosis results in improved prognosis of malignant tumours of the paranasal sinuses.
