Intra-articular osteoid osteoma mimicking juvenile arthritis.

Traore SY, Dumitriu DI, Docquier PL - Case Rep Orthop (2014)

Bottom Line: In case of intra-articular osteoid osteoma, misdiagnosis as juvenile arthritis may occur, delaying adequate treatment.We report cases of intra-articular osteoid osteomas in children that were misdiagnosed and initially inappropriately treated with intra-articular corticoid injection.Clinicians and radiologists should be aware of the potentially confusing clinical and imaging findings associated with intra-articular osteoid osteoma.

ABSTRACT
In case of intra-articular osteoid osteoma, misdiagnosis as juvenile arthritis may occur, delaying adequate treatment. We report cases of intra-articular osteoid osteomas in children that were misdiagnosed and initially inappropriately treated with intra-articular corticoid injection. Diagnosis of osteoid osteoma was finally given by CT-scan and appropriate treatment by radiofrequency ablation or surgical ablation was performed. Clinicians and radiologists should be aware of the potentially confusing clinical and imaging findings associated with intra-articular osteoid osteoma.

Same patient as in Figure 3. (a–c) MRI of the left ankle demonstrates the talar neck nidus, surrounded by abundant oedema and synovial inflammation ((a) sagittal T1-WI, (b) sagittal T2-WI, and (c) axial fat saturated PD-WI). (d) CT-scan of the left ankle also demonstrates the talar neck nidus.

fig4: Same patient as in Figure 3. (a–c) MRI of the left ankle demonstrates the talar neck nidus, surrounded by abundant oedema and synovial inflammation ((a) sagittal T1-WI, (b) sagittal T2-WI, and (c) axial fat saturated PD-WI). (d) CT-scan of the left ankle also demonstrates the talar neck nidus.

Mentions: Considering the persistence of symptomatology, a CT-scan and a MRI (Figure 4) were performed and gave the diagnosis of talar neck OO four months after the onset of pain. The nidus size was 8 mm in the dorsal aspect of the talar neck (Figure 4).
