Osteoid osteoma

Abstract

A 10-year-old girl presented to her pediatrician complaining of intermittent lateral ankle pain for several weeks. There was no history of trauma. The patient was otherwise healthy, with no other pertinent medical history. Physical exam, routine labs and vital signs were normal. An ankle X-ray was ordered and read as normal. The patient was treated conservatively for what her doctor thought may be a bone bruise or sprain injury. Over the course of the next several weeks the patient continued to complain of intermittent ankle pain. Eventually, the patient returned to the pediatrician, at which point the pediatrician ordered an MRI of the ankle.
