A case of 16-year-old female with secondary psoas abscess as the complication of the Crohn’s disease was analysed. Her pre-hospital, long lasting, non-specific symptoms led to ultrasound (US) and radiologic imaging confirming the diagnosis. The antibiotic treatment was insufficient and worsening of the patient’s condition required surgical treatment including descendent colectomy, abscess drainage and negative pressure wound therapy (NPWT). In spite of numerous complications the condition of the child gradually improved and she was discharged from the hospital on the 71st postoperative day. Two years after the colectomy, the occlusion of her colostomy was performed.
Key words: child, Crohn’s disease, psoas abscess
