Benign Chondromyxoid Fibroma of the Iliac Crest

Abstract

A 23-year-old woman initiated a running program and after 2 months began experiencing right hip joint pain and sharp pain at the iliac crest. Following evaluation by her primary care physician, she was referred to a physical therapist. Eighteen months later, the patient had developed a bony prominence at the iliac crest that was painful to touch. She returned to see her primary care physician. Radiographs of the right hip and pelvis were completed and showed a lytic lesion that warranted additional imaging. Computed tomography and magnetic resonance imaging precontrast and postcontrast were performed, and the patient was referred to an orthopaedic oncologist. Conclusive laboratory testing determined that the tumor was a chondromyxoid fibroma J Orthop Sports Phys Ther 2018;48(2):122. doi:10.2519/jospt.2018.7551.

Atypical Location and Appearance of Chondromyxoid of the Right Iliac Wing Fibroma in a Child

“…On flat bones such as the iliac bone, the tumor is often polycyclic and mixed, combining condensation and bone lysis. Intratumoral microcalcifications may be encountered [3,4].…”

“…It should be noted that total resection is not always possible, hence the frequency of recurrence, which reaches 25% of cases. Malignant tumor transformation is exceptional [1,3,11].…”

Chondromyxoid fibroma of the iliac bone: a brief radiological review

“…The occurrence of CMF in the pelvic bones is rare. We conducted a literature review in PubMed by combining the term chondromyxoid fibroma with pelvis, ilium and sacroiliac, and identified several studies relevant to our own, which included 80 cases of pelvic bone CMF with 58 localised to the iliac bones 3 5–21. Of the latter, 17 cases included information on demographics; the median patient age was 36 with a range of 10–68; 8 patients were men and 9 were women.…”
