Patient Data

Age: 79 years
Gender: Male
CT

CT Orbits

Axial: Extensive bilateral retro-orbital soft tissue.  Difficult to evaluate relationship to extraocular muscles in this plane.
Coronal: Extensive bilateral retro-orbital soft tissue.  In this plane, this is shown to be predominantly intraconal and separate from the extraocular muscles, although the muscles do appear bulky, and are probably also involved.

Case Discussion

Lymphoplasmacytic lymphoma was diagnosed histologically from bone marrow biopsy, and this process was therefore assumed to be the same pathology.

Lymphoplasmacytic lymphoma is a rare non-Hodgkin lymphoma.  There are several types, but the commonest type is Waldenström's Macroglobulinaemia.

This appearance in the orbits is usually secondary to a non-Hodgkin lymphoma.  Pseudolymphoma or thyroid orbitopathy predominantly involves the extraocular muscles, without this extensive abnormal tissue in the orbital fat.
