“…The eligible papers and Table give a good impression of the typical case. The relative risk for malignant transformation was raised in the case of finding nodular thickening of the cyst wall on radiology ( P = 0.0023).…”

Aim The best treatment for tailgut cysts has not been firmly established. We report a systematic review of the cases in the available literature in order to provide an evidence base for treatment. Method A systematic search of articles wholly or partly in English was made of PubMed, Embase and Google Scholar; additional studies were discovered by searching reference lists and contacting authors directly. Search terms ‘tailgut cyst’, ‘tail gut cyst’, ‘retrorectal hamartoma’ and ‘retrorectal tumour’ were used for case reports or case series; no publication date restrictions were imposed. Only studies with histological confirmation of diagnosis and reporting the age and gender of patients were included. Papers were excluded by consensus between the first two authors. Results A total of 196 individual cases were analysed in detail including 51 cases of neoplasia. The overall rate of neoplastic transformation was 26.6%. Although the male:female cyst incidence ratio was 1:4, men over 18 had a significantly greater relative risk of neoplasm at 1.94 (P = 0.0055). Radiological evidence of nodular thickening of the cyst wall significantly increased the relative risk of the presence of cancer (P = 0.0023). Conclusions Current orthodoxy that these are not dangerous embryological remnants is unfounded and may be false. The available data suggest the risk of malignant transformation is high and will apply to any residual tissue after excision. The same rationale behind total mesorectal excision in rectal cancer applies to tailgut cysts. Consequently they should be resected with similar oncological margins.

“…Tailgut cysts always present with hypo-intense and homogenous hyper-intense lesions on T1-weighted images and T2-weighted images, respectively. Based on previous studies, MRI may not be the best imaging method to completely distinguish malignant lesions from benign lesions [30,[33][34][35][36][37]. This is because a high content of protein, mucinous tissues, or internal hemorrhage might lead to a high T1 signal intensity, which has been reported in cases of tailgut cyst with malignant transformation [29,38].…”

Departmental sources A tailgut cyst is a type of benign congenital disease that mainly develops in the retro-rectal space. However, malignant transition can occur in some cases of tailgut cysts. Early and precise diagnosis, and proper treatment, are vital for patients with tailgut cysts with malignant transformation. In this review, we aim to summarize the similarities and differences in the diagnosis and treatment methods among the 3 most frequently reported types of tailgut cysts with malignant transformation. In our study, PubMed and Web of Science databases were used to search for the studies and the key words were "tailgut cysts" and "malignancy". We found 176 articles and selected 75 articles in our survey, with 9 reviews, 35 case reports, and 31 case reports and reviews.

“…For the patients with obvious symptoms, the cysts always compress nearby tissues or organs and are always accompanied by infections. [8] For example, if the cysts compress the rectum, defecation can be abnormal and abdominal pain may be obvious; if the cysts compress the bladder or ureter, urination may be abnormal; and if the cysts compress the phrenic nerve, sciatic nerve, or psionic nerve, neuropathic pain may occur. [9] For the cysts that extend to the body surface, fistulas may be observed.…”

Rationale: Tailgut cysts are a type of very rare congenital polycystic lesions that are always located posterior to the rectum and anterior to the sacrum. The symptoms of tailgut cysts are nonspecific and misleading. Therefore, a full understanding of the characteristics of tailgut cysts is important for their diagnosis and treatment. Patient concerns: We report a 46-year-old female with a sacrococcygeal mass that had been present for about 2 years. Diagnoses: Pelvic magnetic resonance imaging (MRI) indicated several cystic masses, the largest of which had a diameter of about 2.8 cm, near the ligaments of the sacrospinous and rectum. Pathological examination confirmed the tailgut cysts, with no signs of malignant transformation. Interventions: The patient received complete surgical cysts resection, which was performed through the sacrococcygeal region. Outcomes: The patient recovered well with no obvious complication and was discharged on the sixth-day post-surgery. Follow-up 6 months later revealed no signs of cyst recurrence. Lessons: The symptoms and diagnostic characteristics of tailgut cysts should be fully understood. Complete surgical resection through the sacrococcygeal region is vital to treat tailgut cysts.
