Abstract
Involvement of the sacrum is extremely rare, and it has also been reported that the diagnosis of osteoid osteoma in the sacrum can be delayed compared to other skeletal locations. We report the case of a six-year-old girl student who complained of chronic back pain for several months and with some relief with non-steroid anti-inflammatory drugs (NSAID). Further investigations, which included bone and CT scan, revealed the presence of an osteoid osteoma at the second sacral vertebra (S2 vertebra). The patient made an excellent recovery after surgical excision.

Summary
The spine is a rare localization of osteoid osteoma and the sacrum is even more exceptional. We report a rare case of a six-year-old girl student who complained of chronic back pain for several months, and who felt some relief with non-steroid anti-inflammatory drugs (NSAID). Further investigations, which included bone and CT scan, uncovered the presence of an osteoid osteoma at the second sacral vertebra (S2 vertebra). A magnetic resonance imaging study was performed revealing subtle signal intensity changes in the sacral region in T1 and T2 images (Figures 4 and 5).
