Abstract
A 6-year-old boy was referred by his general practitioner to our hospital for further investigation of chronic hindfoot pain. An MRI scan was performed. Sagittal IR images revealed bone marrow edema in the anterosuperior portion of the talus (‘talar neck’) with adjacent soft tissue edema (Fig. A). Axial T1 SE depicted a rounded structure with peripheral hypo-intensity within this region of bone marrow edema, suggestive for osteoid osteoma (Fig. B). The presence of an osteoid osteoma was confirmed by CT, which showed a low-attenuation nidus with minimal peri-nidal sclerosis (Fig. C). The patient underwent surgical excision of the lesion. The diagnosis of osteoid osteoma was histologically confirmed.
