UNUSUAL COMPUTED TOMOGRAPHIC MANIFESTATIONS OF BENIGN METASTASIZING LEIOMYOMAS AS CAVITARY NODULAR LESIONS OR INTERSTITIAL LUNG-DISEASE

The unusual computed tomographic manifestations of benign metastasizin g leiomyomas diagnosed in two patients 3 1/2 and 6 years after hystere ctomy for uterine fibroids are described, One showed multiple pulmonar y nodules with a round or irregular air-filled cavity representing obs tructive emphysema. The other showed interstitial lung disease with tu mor cells spreading along alveolar septa, the vascular wall, and the b ronchial tree. We consider such metastasizing tumors as low-grade leio myosarcomas.
