Recent studies show active tuberculosis induces a prothrombotic state and increases the risk of venous thromboembolism. We report a recently diagnosed case of tuberculosis who presented to our hospital with painful bilateral lower limb swelling and several episodes of vomiting with abdominal pain for 2 weeks. Investigations by a hospital elsewhere 2 weeks ago showed abnormal renal function, misdiagnosed as antitubercular therapy-induced acute kidney injury. D-dimer levels were increased on admission with us, with still deranged renal function. Imaging revealed thrombus at the origin of left renal vein, inferior vena cava and bilateral lower limbs. We started treatment with anticoagulants, which gradually improved kidney function. This case highlights that early diagnosis of renal vein thrombosis and prompt treatment are associated with good clinical outcomes. It also highlights the importance of further studies for risk assessment, prevention strategies and reduction of the burden of venous thromboembolism in patients with tuberculosis.
