Pulmonary Embolism in a Patient with Antiphospholipid Syndrome and Graves' Disease

Antiphospholipid syndrome (APS) is an autoimmune disease characterised by tendency to thrombosis, obstetrical and hematological complications. Patients with Graves' disease (GD) may have some abnormalities of blood coagulation due to endothelial dysfunction and decreased fibrinolytic activity with a higher thromboembolic potential. In some rare cases especially in severe thrombotic states; APS and GD may be present together. We describe a 44-year-old man with pulmonary embolism who had both APS and GD. Morover thymic hyperplasia which is a seldom-recognized feature of GD was also established in computed tomography of the chest and thyroid stimulating hormone level was in the normal range probably due to antibody interference.
