肛周化脓性汗腺炎的核磁共振表现分析*

目的: 探讨磁共振成像(magnetic resonance imaging,MRI)对肛周化脓性汗腺炎( hidradenitis suppurativa,HS)诊断分期及治疗的临床应用价值。方法: 回顾性分析2018年1月至2020年12月就诊于包头医学院第二附属医院皮肤科及肛肠科的肛周HS患者的临床及MRI资料,结合临床Herley 分期,观察MRI显示的HS病灶分布与严重程度。结果: 10例患者中Herley Ⅰ期6例,Ⅱ期 4例,Ⅰ期患者MRI表现为局灶性炎症及脓肿,未见窦道。脓肿见于肛周(83 %),之后依次为臀区(50 %)、前会阴区(33 %)。Ⅱ期患者MRI表现为皮下组织炎症、脓肿及窦道,窦道未侵犯肌肉、肛管,未见窦道相互连接。4例患者中窦道见于肛周(100 %),前会阴区(25 %),臀区(25 %),坐骨直肠窝(25 %),臀沟(25 %)。脓肿见于肛周(100 %),前会阴区(50 %),臀区(50 %),坐骨直肠窝(25 %),臀沟(25 %)。本组患者MRI表现与临床分期一致。结论: MRI检查可明确肛周HS病变范围及深度,确定Herley 分期,为肛周HS的诊断、治疗及疗效判定提供客观的影像学依据。

Magnetic resonance imaging features of Anorectal hidradenitis suppurativa

Objective: To assess the value of application of magnetic resonance imaging in anogenital hidradenitis suppurativa. Methods: We collected the MRI images of patients diagnosed with HS in the department of Dermatology of the Second Affiliated Hospital of Baotou Medical Colledge between 2018.1 to 2020.12. The manifestations of clinical stage and MRI were analyzed and compared. Results: The 6 patients diagnosed with HS in Herley Ⅰpresented with inflamation and abcesses.The abcesses were seen in the perianal (83 %), the perineal(33 %),the gluteal(50 %).4 patients diagnosed with HS in Herley Ⅱpresented with sinuses and scar except inflamation and abcesses. The abcesses were seen in the perianal (100 %), the perineal(25 %),the gluteal(25 %), the natal cleft(25 %),the ischioanal fossa(25 %).The sinuses were seen in the perianal (100 %), the perineal(100 %),the gluteal(50 %),the natal cleft(25 %),the ischioanal fossa(25 %).No communication was found between anal canal and the abcesses or sinuses.The MRI feature was corresponding to the Herley stage. Conclusion: MRI can define the extent of HS which provide imaging evidence for treatment.
