Abstract
The patient was a 44-year-old man who had diabetes that had gone without treatment for one year. He was hospitalized with chief complaints of lumbago and pain in the right lower limb. Hyperglycemia leukocytosis a positive CRP test and erythrocyte hypersedimentation were seen and Staphylococcus aureus was detected by urine culture. Abscess of the right iliopsoas muscle was found by CT scan. Treatment with antibiotics resulted in symptomatic improvement and the patient was discharged one month later. Two months after discharge he was re-hospitalized with a recurrence of lumbago and pain in the left lower limb. Abscess of the left iliopsoas muscle was detected by CT scan and antibiotics were again administered. However the abscess did not disappear and incision and drainage were performed. One month later disappearance of the iliopsoas muscle abscess was confirmed by CT scan. We speculate that this patient with non-insulin-dependent diabetes mellitus developed a urinary tract infection becaused of inadequate blood glucose control and that this infection led to an iliopsoas abscess which later recurred on the contralateral side. The experience with this case indicates the necessity of adequate care in cases of diabetes complicated by iliopsoas abscess.
