title: Crohn's Disease Causes a Catastrophe.
abstract: Patients with Crohn's disease are at higher risk of developing antiphospholipid antibody syndrome (APS), of which 1% develop life-threatening, rapidly progressive clotting known as catastrophic APS (CAPS). A 17-year-old male presented with intermittent bloody diarrhea and abdominal pain. He developed myopericarditis, alveolar hemorrhage, left frontal and parieto-occipital infarct, superior sagittal sinus venous thrombosis, disseminated intravascular coagulation, and a pulmonary embolus. He was treated with high-dose pulse steroids, anticoagulation, and plasma exchange. Colonoscopy revealed a flare of Crohn's disease, and azathioprine was initiated.
