A perianal mass has a wide range of possible diagnoses, including tailgut cysts. Tailgut cysts are congenital, and their development is slow. Because its most common placement is retro-rectal, it is extremely rare to find it on the perianal level only. It is possible to develop neoplastic or infectious problems. Consequently, proper support is required.
We present a case of perianal tailgut cyst in a 59-year-old man who sought help for painless anal discomfort. Nuclear magnetic resonance was used to conduct this assessment. The radiologist thought it was probably benign, but he was not able to find a precise diagnosis. Thus, the cyst was completely removed using a transanal way with the patient in a lithotomy position. Then, the anatomopathological examination had confirmed the diagnosis and the benignity of the cyst. The postoperative follow-up was uneventful. We had planned to see the patient for a clinical follow-up every six months, but he has refused so far.
Tailgut cysts are uncommon in the perianal area but should be included in the differential diagnosis of perianal masses and should not be confused with an abscess or a haemorrhoid. The nuclear magnetic resonance appears to be the most appropriate radiological examination for the assessment of these masses. Excision is performed systematically to confirm the diagnosis and exclude a malignant condition thanks to the anatomopathological examination.
肛周肿物有多种可能的诊断，包括尾肠囊肿。尾肠囊肿是先天性的，其发展缓慢。由于其最常见的位置是直肠后方，仅在肛周水平发现极为罕见。它可能会出现肿瘤性或感染性问题。因此，需要适当的支持。
我们报告一例59岁男性肛周尾肠囊肿病例，该患者因无痛性肛门不适寻求帮助。采用核磁共振进行评估。放射科医生认为其可能为良性，但无法做出精确诊断。于是，患者取截石位，经肛门完全切除囊肿。随后，解剖病理学检查确诊了囊肿并证实其为良性。术后随访无异常。我们原计划每六个月对患者进行一次临床随访，但他至今拒绝了。
尾肠囊肿在肛周区域并不常见，但应列入肛周肿物的鉴别诊断，且不应与脓肿或痔疮相混淆。核磁共振似乎是评估这些肿物最合适的影像学检查。通过解剖病理学检查进行系统切除以确诊并排除恶性情况。
