Orbital giant cell myositis is an unusual and potentially lethal cause of bilateral ophthalmoplegia – A case report and literature review

ABSTRACT

We present a case of orbital giant cell myositis (OGCM), presenting with bilateral subacute progressive ophthalmoplegia and optic nerve dysfunction. An early extraocular muscle biopsy confirmed the diagnosis and guided appropriate management. Comprehensive investigation excluded any underlying systemic disease, including myocarditis. Twenty two months after presentation, the patient remains well on azathioprine with complete resolution of orbital signs.
