INTRODUCTION The extraocular muscle (EOM) is the most frequent site for the involvement of thyroid orbitopathy, followed in order by inferior, medial, superior, lateral rectus, and oblique muscles. The EOM is the rarest site for the involvement of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the orbit. Several cases of MALT lymphoma involving the EOM have appeared in the English literature, and most of these are in the form of case reports
more » ... of case reports (1-5). The imaging findings of MALT lymphoma involving the EOM are limited to those of a single imaging modality only (1-3). As such, imaging features of this rare entity at CT, MRI, and 18 F-fluorodeoxyglucose positron emission tomography/CT ( 18 F-FDG PET/CT) altogether in a single case have not appeared in the literature.
