Leiomyoma of the lung may be a solitary lesion, radiographically indistinguishable from the other benign connective tissue neoplasms. Multiple leiomyomas present as multiple discrete nodules in the lungs. They are given a wide variety of names, including benign metastasising leiomyoma. In women these tumours may be very slow-growing metastases from a uterine leiomyoma; women with multiple pulmonary leiomyomas often have a history of previous hysterectomy for uterine fibroids.

Intrapulmonary teratomas are very unusual. Most are benign, though malignant lesions are occasionally encountered. Radiographically, and on CT, intrapulmonary teratomas appear as lobulated masses that may show calcification or cavitation.
