A 67-year-old woman with symptoms of shock was admitted to hospital with a suspected diagnosis of acute pulmonary artery embolism. After ruling out a thromboembolic event, sepsis was diagnosed by using the SOFA score. A CT scan of the chest with contrast revealed phlegmonous inflammation of the subcutis at the level of the right upper arm. After taking two pairs of peripheral blood samples, calculated antibiotic therapy with piperacillin/tazobactam was administered. After administration of an initial volume bolus, the patient could be transferred to the general medical ward in a stable condition with normal serum lactate level. On day one after hospital admission, blood cultures were positive for Pasteurella multocida, a gramnegative rod that belongs to the oral flora of dogs and cats. Intensified history revealed that the patient had been bitten on the forearm by her cat 2 weeks earlier. The patient did not present to a general practitioner. Despite antibiotic therapy, the patient developed increasing leukocytosis with progressive pain and swelling in the area of the right upper arm and the right ankle. On recommendation of the department of infectious diseases antibiotic therapy was escalated to imipenem and transesophageal echocardiography was performed. Endocarditic vegetations could be ruled out. Despite further escalation of the antibiotic regimen, spontaneous pus discharge occurred at the right ankle. A CT scan of the chest as well as the foot and the right ankle with contrast showed new abscess formations in the right thoracic wall between the pectoralis major and minor muscles as well as extensive abscesses in the extensor compartment of the right lower leg. On day 12 after admission, surgical drainage of multiple abscesses was performed, with rapid improvement in general condition and normalized leukocytes. A further six operations were necessary before the patient could be discharged home after 7 weeks of inpatient treatment., (© 2021. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)
