Trigger point injections as a potential risk for psoas abscess トリガーポイント注射は腸腰筋膿瘍の要因となりうる Kamiya, Naoko Matsumura, Masami aged patient compromised patient psoas abscess trigger point injection 高齢者 易感染性宿主 腸腰筋膿瘍 トリガーポイント注射 A 92-year-old man taking 5 mg per day of oral prednisolone presented with exacerbation of low back pain. He had been received frequent trigger point injections (TPIs) for lumbar canal stenosis. Physical examination revealed an area of tenderness on the right lower back which was consistent with the location of the TPIs and the contrast computed tomography (CT) scan showed an intramuscular abscess in the right iliopsoas. He was transferred to the tertiary medical institution, and the culture obtained by CT guided percutaneous abscess drainage yielded Streptococcus pyogenes, which is a part of the skin flora and pathogenic bacteria. Psoas abscess might have been caused by frequent TPIs in this case. This case report illustrates TPI is a potential risk factor for muscle abscess, especially in aged and compromised patients. 自治医科大学 2022-03 eng departmental bulletin paper https://jichi-ir.repo.nii.ac.jp/records/1123 1881-252X 自治医科大学紀要 Jichi Medical University Journal 44 27 29 https://jichi-ir.repo.nii.ac.jp/record/1123/files/自治医科大学紀要 1881-252X(44)p27-29 2022.pdf application/pdf 230.6 kB 2022-06-07
