Female, 81 years old, with non-Hodgkin's lymphoma. Surveillance scan. On comparison with the prior examination, continued interval regression is seen of the infiltrative pathologic enhancement and thickening involving the right orbital structures including the superior and lateral recti, the lacrimal gland, and the orbital fat. Minimal residual stranding persists, but there is no longer any definite or significant mass effect on the orbital structures.No additional pathologic enhancement is identified in the orbits or intracranially. Scattered punctate foci of T2 hyperintensity within the bilateral cerebral white matter have not significantly changed from prior and are nonspecific. No evidence of parenchymal edema or mass effect is seen. No intracranial hemorrhage or abnormal extra-axial fluid is seen. The ventricular system is stable and within normal limits for size.
1.Continued interval regression of an infiltrative lesion involving the structures of the right orbit. There is only minimal residual stranding in the orbit with no evidence of significant mass effect.2.No findings to suggest intracranial disease involvement.
