MRI of the orbits identified a nonspecific appearing mass medial to the right orbit (Figure 1).
Head CT without contrast. After two cycles of R-CHOP therapy, interval CT scan revealed a significant decrease in size of right intraorbital mass lesion medially with small residual mostly in the medial extraconal space.
