A sixty-year-old man with ulcerative colitis and polymyalgia rheumatica, for which he was receiving prednisolone, visited the emergency department complaining of a gradual worsening of pain in the right buttock. Physical examination revealed mild redness and tenderness at the right side of the anus. Ultrasound revealed an approximately 38-mm long, avascular subcutaneous collection with heterogeneous echogenicity in the tender region. A perianal abscess was diagnosed, the lesion was punctured, and pus was drained, after which the pain improved. Point-of-care ultrasonography was effective in the prompt diagnosis and subsequent treatment of this patient's perianal abscess.
一名60岁男性，患有溃疡性结肠炎和风湿性多肌痛，正在接受泼尼松龙治疗，因右臀部疼痛逐渐加重而前往急诊科就诊。体格检查发现肛门右侧轻度发红和压痛。超声检查显示在压痛区域有一个长约38毫米、无血管的皮下积液，回声不均匀。诊断为肛周脓肿，对病变进行穿刺并排出脓液，之后疼痛缓解。即时超声检查对该患者肛周脓肿的快速诊断和后续治疗有效。
