Lacrimal gland lymphoma

Case contributed by Dr Ahmed Abd Rabou

Presentation

Gradual onset of left side painless proptosis was observed.

Patient Data

Age: 52
Gender: Female
Modality: MRI

A well circumscribed left orbital extra conal mass lesion occupying the lacrimal fossa and compressing the left lateral rectus inferomedially, the superior rectus medially and the globe anteriorly. The lesion returns intermediate signal on T1, T2 and STIR with moderate enhancement on post contrast study.

No evidence of fat stranding, orbital or bony invasion.

Case Discussion

Histopathological specimen from the excised mass revealed MALT lymphoma. The imaging features are typical for lymphoma as the high cellularity of the tumors renders them of intermediate or low signal on T2 WI. Unfortunately DWI wasn't available in this study although it would be of great help.
