Radiographic presentations of OAML. (A) CT image of right orbital MALT lymphoma involving the inferior rectus muscle, causing mild proptosis. (B) MRI of left orbital MALT lymphoma involving the lateral and inferior rectus muscles, causing medial deviation of the optic nerve, with involvement of the cavernous sinus (white arrow) and mild dural enhancement in the medial anterior cranial fossa (black arrow). Analysis of the cerebrospinal fluid was positive for lymphoma. This case represents an unusual extension of OAML into the central nervous system leading to lymphomatous meningitis.
