A Case of Adenocarcinoma of the Lung Combined with Solitary Osteosclerosis Resembling Metastasis in the Cranium

A 35 year-old man was admitted to our hospital for treatment of cancer of the right lung. Bone scintigraphy showed a large solitary accumulation that seemed to be a metastatic lesion in the occipito-temporal area. Right upper lobectomy of the lung and removal of the right occipital bone were performed. Histological findings showed adenocarcinoma of the lung and osteosclerosis of the occipital bone but no cancermetastasis. The significance of a solitary accumulation on bone scintigraphy in patients with lung cancer was discussed with paticular reference to preoperative diagnosis.
