Lee, Kang, Lee, Jeong, Jo, Seong, Woo, and Jeong: A Case of Azygos Vein Thombosis Associated with Transient Antiphospholipid Syndrome in Urinary Tract Infection with Escherichia coli

Abstract

A 73-year-old female with diabetes admitted for treatment of an intertrochanter fracture of the femur and a urinary tract infection (UTI) with Escherichia coli developed thrombosis in her right azygos vein, which was thought to be associated with anti-phospholipid and immunoglobulin M anticardiolipin antibodies. After antibiotic therapy, antiphospholipid antibody was undetectable, and a repeat chest computed tomography showed complete resolution of the azygos vein thrombosis. A wide variety of infections can be associated with thrombotic events in patients with transient antiphospholipid syndrome (APS), and this case serves as a reminder that the possibility of transient APS should be considered in patients with venous thrombosis in the setting of a UTI.
