Benign metastasizing leiomyoma is typically seen in young
premenopausal women after a mean period of 15 years following
uterine leiomyoma or hysterectomy surgery. They are usually
incidentally seen on chest x-rays and are nodular lesions that
appear as bilateral nodules with a benign appearance and consist of
smooth muscle proliferation. A 44-year-old female presented at her
healthcare institution for backache for the last 9 months. Multiple
nodules (largest 15 mm) scattered in both lungs and consistent with
metastases were detected on computed tomography. The PET-CT
results revealed multiple nodular densities with increased metabolic
activity (SUVmax: 1.92) in both lungs, with the largest one measuring
approximately 15 mm and located in the lower lobe superior segment
of the right lung. A benign metastasizing leiomyoma was diagnosed
with open wedge biopsy of the lung. We present this case due to
its interesting clinical presentation and rarity and emphasize the
pathogenesis.
