Orbital myositis as an initial manifestation of Behcet's disease.

PURPOSE: We report the case of a 32-year-old woman with orbital myositis prior to onset of Behcet's disease (BD).

OBSERVATIONS: A 32-year-old woman was referred to our hospital for a complaint of right eyelid swelling, eye pain, and diplopia. Her best-corrected visual acuity was 20/32 on the right, and 20/16 on the left. She was diagnosed as idiopathic orbital inflammation, and received two pulses of intravenous administration of methylprednisolone, followed by oral prednisolone. Three months later, she developed bilateral orbital myositis, and received one more pulse therapy, followed by oral prednisolone and cyclosporin. About one year after the first visit, oral aphthae, genital ulcers, and folliculitis-like skin rash appeared, and the physician diagnosed incomplete type BD. The patient had no uveitis during the disease course. Orbital inflammation and systemic manifestations of BD were ultimately well controlled with small doses of prednisolone.

CONCLUSION AND

IMPORTANCE

BD may develop during the course of orbital inflammation.
