Case in brief
A 67-year-old female with a history of breast carcinoma presented with multiple lytic osseous lesions in the pelvis and scapula, initially thought to be metastatic disease. Comprehensive imaging, including radiographs, CT, MRI, and PET/CT, led to a biopsy that confirmed benign metastasizing leiomyoma. This case highlights the imaging characteristics of this rare condition.
What made this case unusual
Osseous involvement of benign metastasizing leiomyoma is rare, with fewer than 20 cases documented, primarily affecting the spine.
Diagnostic / clinical pearl
Clinicians should maintain a high index of suspicion for benign metastasizing leiomyoma in women with a history of uterine leiomyomas presenting with new bone lesions.
Why it matters
Awareness of benign metastasizing leiomyoma's imaging features is crucial for accurate diagnosis and differentiation from malignant processes.
