[Cerebellar and pulmonary metastases from papillary thyroid carcinoma. Report of a case]

We are reporting the clinical case of a male who was diagnosed as papillary thyroid carcinoma with cervical, cerebellar and lung metastases. Although in theory it was a well differentiated tumour and slow progression with a good prognosis, there was a very aggressive spread in our patient up to his death. We decided not to operate him and send him to the Oncology Service for chemotherapy that was unsuccessful. The intracranial metastases due to papillary thyroid carcinoma are very uncommon (about 1%) on the contrary of cervical ones, but their behaviour is more aggressive and frequently associated to other metastases on bone or lung.
