title: Side-locked headache as the chief complaint of inflammatory orbital pseudotumor (myositic form): a case report.
abstract: The case of a 38-year-old woman with continuous unilateral side-locked headache is reported. She had continuous right-sided periorbital pain of mild to moderate intensity for the past 5 months. She also reported a few episodes of pain exacerbations every day. She had no autonomic features. Based on a normal CT scan ordered by her general physician, we started indomethacin (150 mg/day) as well as celecoxib (400 mg/day) for 2 weeks, without relief. Oral prednisone for 6 days provided important relief, and she stayed on daily use of steroids, refusing other forms of therapy. After 5 months she developed orbital and eyelid edema, with painful restrictions to eye movement. Orbital MRI and pathological exam demonstrated inflammatory orbital pseudotumor (myositic form).
