Venous thrombosis associated with psoas abscess: successful treatment with percutaneous drainage of abscess and antibiotics / 대한내과학회지

ABSTRACT

We report an unusual case of venous thrombosis complicated by pyogenic psoas muscle abscess in a patient with chronic biliary tract disease. A 64-year-old woman presented with high fever and progressive back and left flank pain. She had been admitted because of recurrent cholangitis and liver abscess 7 months ago. Both abscess and blood cultures had revealed Klebsiella pneumoniae and she had improved with treatment of antibiotics and percutaneous drainage of abscess. Computed tomography demonstrated psoas abscess and thrombosis of inferior vena cava and left iliac vein adjacent to abscess. Several days later, abscess culture showed Klebsiella pneumoniae. Because there was no evidence of deep vein thrombosis and the thrombosis was confined only to the vein adjacent to the abscess, we considered that the thrombosis would be associated with the abscess. She was immediately treated with percutaneous drainage of abscess and antibiotics. Follow-up computed tomography demonstrated complete disappearance of both psoas abscess and venous thrombosis.
