Abstract
A 59 year-old man was admitted to our department complaining of ataxia, astasia and nystagmus. Chest X-ray revealed a small mass shadow in the left lower lung field.Transbronchial brushing specimens showed small cell carcinoma. Cerebral CT scan showed no findings suggestive of metastasis.
Under a diagnosis of lung cancer with subacute cerebellar degeneration, left lower lobectomy with partial resection of S5 was performed.
Preoperative plasmapheresis and steroid therapy were not effective, but improvement of cerebellar symptoms was seen for 1 week postoperatively. The histological diagnosis was intermediate type small cell carcinoma.
