Iliopsoas abscess with iliac and femoral vein thrombosis in an adult Siberian husky

A nine-year-old, male Siberian husky was presented with fever, decreased appetite and activity, non-weightbearing lameness, and oedematous swelling of the right inguinal and preputial area and the right hindlimb. An abscess within the right iliopsoas muscle, with severe thrombosis of the iliac and femoral vein, was diagnosed by haematology and diagnostic imaging. The abscess and adjoining lymph node were removed surgically through a median coeliotomy. The isolated pathogen was Staphylococcus intermedius. Clinical signs resolved completely after surgery. Antimicrobial therapy was continued for four weeks. Within the follow-up period of six months, no recurrence of the clinical signs was detected.
