Objective To analyze the CT characteristics of pulmonary benign metastasizing leiomyoma (PBML) and improve the recognition of this disease. Methods CT imaging features of 6 patients with PBML confirmed by histopathology were retrospectively reviewed. Imaging findings of the number, location, morphology, size,margin, inner structure and accompanying signs were assessed. Results All cases were female with a history of hysteromyomectomy. The imaging of PBML manifest multiple and welldefined nodules. The distribution was random with a preference of inferior lobes. Nodules may appear as solid, cave with thin-wall or cystic-solid lesions and lobular types could appear on some instances. No burr was seen.Tumors revealed homogeneous or inhomogenous density and showed moderate to intense enhancement after administrating contrast agent while calcification and air bronchogram were rarely seen. Neither the swelling of mediastinum/hilar lymph nodes nor the dropsy of the pericardium/ thorax was presented in any cases. Conclusion PBML is a rare disease with a history of hysteromyomectomy. When multiple well-defined nodules without swelling of the mediastinum/hilar lymph nodes or dropsy of the pericardium/thorax were manifested, a possibility of PBML should be considered .
