The patient is a 75-year-old man who had a resection of meningotherial meningioma of the left edge of sphenoid bone at the age of 50. The diseases had recurred in the local site, and he had resections at the ages of 52 and 54. Whole-brain radiation therapy was performed at the age of 54. Sputum and cough appeared at the age of 73, and multiple nodules in bilateral lungs were pointed out in the chest X-ray, and the chest CT. FDG/PET showed SUVmax 6.1 in the largest mass. The nodules were diagnosed as metastatic lung tumors of meningotherial meningioma according to the immune-stained pattern of the CT-guided fine-needle lung biopsy tissues compared with those that had been resected 23 years ago. We should note that meningotherial meningioma metastasizing to extracranial organs may occur without a local relapse after a long period.
