Case study orbital lymphoma

Lobulated fluid mass in the right superolateral orbit, measuring 3.8 x 2.6 cm transversely. The mass abuts and slightly displaces the globe and is inseparable from the lateral rectus and superior oblique muscles. The mass extends posteriorly along the lateral orbital wall, but does not encroach upon the orbital apex. Smaller mass in the same position in the left orbit, measuring 2.2 x 1.1 cm, also unchanged from previously. No abnormality is seen elsewhere within the skull base or visualised brain.
