Abstract
BACKGROUND

Diffuse fasciitis with psoriatic arthritis on magnetic resonance imaging (MRI) has not been previously described in childhood. Here we present the first case report of a pediatric patient developing fasciitis, beyond plantar fasciitis, with psoriatic arthritis.

CASE SUMMARY

An 11-year-old female was admitted with the complaints of psoriatic rash on the body associated with severe pain in the lower extremities and arthritis in the right knee. Psoriasis was confirmed by skin biopsy, she diagnosed with juvenile psoriatic arthritis. Diagnostic tests did not indicate any pathology except MRI. MRI of the femur and tibia revealed that high-signal inflammatory changes in the subdermal fascia. These findings led to a diagnosis of psoriatic fasciitis. Methotrexate was given for 3 mo but the patient showed no response to therapy; therefore, etanercept was added. However, there was no response to treatment. Etanercept was switched to adalimumab at the sixth month of therapy. Clinical improvement started with therapy of adalimumab within one month. Fasciitis finding in MRI disappeared at seventh months on adalimumab therapy. She has no complaint for two years with adalimumab.

CONCLUSION

The most effective imaging method is MRI and adalimumab may be the best choice of treatment for psoriatic fasciitis.

Core tip: Plantar fasciitis may be observed on magnetic resonance imaging (MRI) in patients with psoriatic arthritis. However, to our knowledge, MRI findings of diffuse fasciitis associated with psoriatic arthritis have not been previously described in a pediatric patient. Fasciitis should be considered in patients with psoriatic arthritis, especially with unresolved extremity pain. MRI seems to be the most effective imaging method and adalimumab may be the best choice of treatment for psoriatic fasciitis.
