Abstract
Extraocular muscle enlargement can occur secondary to a range of orbital and systemic diseases. Although the most common cause of extraocular muscle enlargement is thyroid eye disease, a range of other inflammatory, infective, neoplastic, and vascular conditions can alter the size and shape of the extraocular muscles. Imaging with computed tomography and magnetic resonance imaging plays an essential role in the workup of these conditions. This article provides an image-rich review of the wide range of pathology that can cause enlargement of the extraocular muscles.

Abstract
A 66-year-old female presented with a 6-month history of increasing right-sided facial pain and diplopia. Right ocular movements were restricted in adduction and downgaze. Superior oblique (SO) enlargement was seen on an initial MRI scan, and subsequent diffuse infiltration was seen on a repeat scan. An elevated cANCA and biopsy of SO confirmed Wegener's granulomatosis (WG). We report a case of SO myositis as a predominant early feature of WG granulomatosis and review the literature regarding extraocular muscle involvement in WG. To our knowledge, early SO involvement has not been reported.
