Metastasis from primary tumours to the paranasal sinuses is infrequent. We report an unusual case of breast cancer metastasis presenting as ethmoiditis in MRI. MRI changes are unspecific and sometimes inflammatory lesions can not be distinguished from neoplastic lesions. Inflammatory changes in the paranasal sinuses are also frequently noted on MRI even in normal persons without disease. A high index of metastasis suspicion in any patient with breast cancer must be kept in mind.
