20-years old girl with back pain since Feb 2019. MRI of Apr 2019 showed right L4 pedicle marrow edema. Nothing was done. Her pain continued and a repeat MRI of October 2019 showed the same marrow edema. She had typical pain that was more at night and responded to anti-inflammatory drugs. She was sent for a biopsy. We did a CT scan that showed a classic osteoid osteoma at the tip of the superior articular facet of the L4 vertebra, that we subsequently did an RFA for.
