Mononeuritis multiplex, protein-losing gastroenteropathy, and choroidopathy seen together in a case of systemic lupus erythematosus

A 43-year-old woman with systemic lupus erythematosus (SLE) had an episode of mononeuritis multiplex prior to developing protein-losing gastroenteropathy. Four years later, she had another episode of mononeuritis multiplex, followed by choroidopathy. These manifestations are uncommon in SLE, but may be attributed to vasculitis. The laboratory findings indicated that the elevation of D-dimer and thrombin-antithrombin complex levels seen in this case might be useful in evaluating vascular lesions in SLE.
