title: Cranial nerve dysfunction in metastatic cancer of the prostate.
abstract: We report 11 patients with cranial nerve dysfunction due to bone metastases from advanced prostatic cancer. Diplopia, speech disturbances, tongue deviation and headache were the typical clinical symptoms. X-ray and/or computed tomography of the base of the skull demonstrated bone destruction (and the surrounding soft tissue tumour) in 8 cases. In 1 patient the bone destruction was visualised only by bone scan. In 2 cases no bone destruction could be demonstrated in spite of the clinical findings. In 9 of the 10 evaluable patients the clinical symptoms improved after high voltage radiotherapy and high dose corticosteroid treatment. Cranial nerve dysfunction is a late complication of hormone-resistant prostatic cancer. The symptoms are usually due to bone destruction at the base of the skull. Radiotherapy combined with corticosteroid treatment is an excellent palliative measure if started immediately after the onset of symptoms.
