Pseudo-pseudo Meigs' syndrome (PPMS) in chronic lupus peritonitis: a case report with review of literature.

Gastrointestinal involvement in systemic lupus erythematosus (SLE) usually occurs in the form of mesenteric vasculitis, protein-losing enteropathy, intestinal pseudo-obstruction, and pancreatitis. We describe a 23-year-old female, a known case of SLE presented with significant ascites and pleural effusion. Further evaluation showed elevated CA-125 levels without evidence of malignancy. The patient was treated with corticosteroids, hydroxychloroquine, and azathioprine resulting in the resolution of ascites in 2 weeks. The triad of ascites, pleural effusion, and increased CA-125 is known as pseudo-pseudo Meigs' syndrome, which is rarely reported in the literature. Clinicians should be aware of this entity while evaluating an SLE patient with low serum-ascites albumin gradient (SAAG) ascites.
