[Orbital myositis, recurrence of Whipple's disease]

Whipple's disease, a chronic systemic and multi-organ disease can be associated with ophthalmological manifestations with or without CNS involvement. Myositis rarely occurs during Whipple's disease. Antibiotic treatment prevents CNS recurrence. We report here the association of an orbital pseudotumor with Whipple's disease. This myositis was discovered on a follow-up CT examination. It appeared only one year after the end of a long course of antibiotic treatment, but it resolved within a few weeks when treatment was reintroduced. Relations between these two diseases are discussed.
