The use of whole-body MR imaging in children with herditary multiple
osteochondromas
Background: Patients with hereditary multiple
osteochondromas (HMO) undergo frequent radiographs
to evaluate the growth of their osteochondromas. The
conventional radiographic images clearly show the growth
of the bony part of the osteochondromas and the growth
direction of the long bones. The radiographs do not show the
cartilage cap on top of the osteochondroma nor do they show
the surrounding soft tissue or the cartilage of the nearby
epiphysis. Alongside these disadvantages, taking frequent
radiographs carry the potential risk of inducing malignant
degeneration through ionizing radiation. We investigated the
use of whole-body MR imaging as a screening tool to follow
patients with HMO.
Findings: Two HMO affected children underwent two
whole-body MR imaging scans in one-year time to identify
the osteochondromas and to evaluate their growth.
The MR images were compared to regular follow-up
radiographs of these patients. All radiographically detectable
osteochondromas were visible on the whole-body MR
images. At least one osteochondroma was clearly seen on
the whole-body MR images before detection was possible
on the radiographs. The proton density sequence with fat
suppression proved to be the best sequence to visualize
osteochondromas.
Conclusion: Whole-bodyMR imaging is an effective follow-up
tool for patients with hereditary multiple osteochondromas
