[Occult papillary carcinoma of the thyroid gland with unusual neurologic symptoms]

We present a patient who had progressive cognitive decline and Jackson epileptic seizures and CT scan of nonspecific multiple cortical lesions. Post mortem examination revealed multiple cortical metastases of the brain and primary occult papillary carcinoma of the thyroid gland. Solitary metastases of the left kidney and pulmonary lymphangitic spread were also present. Multiple cortical metastases of the brain from primary occult papillary carcinoma of the thyroid gland with such neurological symptoms have not been reported previously.
