title: [Iatrogenic foreign body of the ethmoid sinus misdiagnosed as tumor].
abstract: Foreign bodies in the paranasal sinuses are rare. Foreign bodies in the ethmoid sinus are easily misdiagnosed as tumor. There is no typical display in CT and MRI tests. The described case showed the misdiagnosis of an ethmoid foreign body as tumour on the basis of CT and MRI results. It should be emphasised that the tumour diagnosis should be based on further physical and histopathological examinations and not only on the results of CT and MRI tests.
