Case contributed by Dr Roberto Schubert


Left exophtalmos, diplopia, conjunctival swelling since some days.

Patient Data

Age: 55
Gender: Female

Largely extraconal mass lesion in the upper outer left orbital quadrant with low signal on T1 and T2-weighted images, and homogeneous contrast enhancement. Involvement of the lacrimal gland and the adjacent conjunctiva. The lateral rectus muscle is displaced medially.


One year later, after surgical resection and chemotherapy.

Resolution of lesion is seen after resection and chemo-radiotherapy. Good response is seen. Mass is completely resected.

Case Discussion

Lymphoma accounts for 50% of malignant orbital tumors. Due to its high cellularity, it often has low signal intensity on T2 (isointense to muscle).
