“…CT examination shows a well-defined multicystic mass, with values of density varying from that of water to that of soft tissues (55). On NMR, a tailgut cyst typically demonstrates low signal intensity on T1-weighted images and high signal intensity on T2-weighted images (56).…”

Detection and management of retroperitoneal cystic lesions: A case report and review of the literature

Abstract. The identification of cystic lesions within the retroperitoneal space is a rare event that poses clinicians the challenge of a difficult diagnosis and disease management. Retroperitoneal cystic lesions account for a group of lesions that range from common benign lesions (e.g., lymphoceles developing as a surgical complication) to rare aggressive malignant neoplasms. Currently, in the majority of cases, image-guided procedures allow for a pathological diagnosis to be achieved in these challenging lesions, thus offering the chance of an appropriate treatment; however, the overall clinical assessment of retroperitoneal cysts is highly demanding. The present study reports the management of a representative clinical case, presenting with a voluminous cystic mass able to dislocate cave vein, whose diagnosis was preceded by a deep vein thrombosis. Computed tomography-scan and ultrasound guided percutaneous drainage were performed to achieve the diagnosis. Following the discussion of the current case report, a review of the pathological and radiological characteristics of retroperitoneal cystic lesions is presented.

“…Preoperative diagnosis is very difficult and various diagnostic methods are used. Pelvic MRI is the imaging method of choice in differentiating tailgut cysts from other lesions [6,9]. Tailgut cysts usually have a low signal intensity on T1-weighted images and high signal intensity on T2-weighted images [9,10].…”

“…Pelvic MRI is the imaging method of choice in differentiating tailgut cysts from other lesions [6,9]. Tailgut cysts usually have a low signal intensity on T1-weighted images and high signal intensity on T2-weighted images [9,10]. MRI is more sensitive than computed tomography (CT) scan in differentiating unilocular and multilocular tumors and especially for the detection of small peripheral cysts [10].…”

“…Tailgut cysts are usually benign and malignant transformation is rare. Cases of malignancies include adenocarcinoma, carcinoid tumors, neuroendocrine carcinoma, endometrioid carcinoma, adenosquamous carcinoma, squamous cell carcinoma and sarcoma have been reported to be associated with tailgut cyst and adenocarcinoma, and carcinoid tumors are the most common malignant transformation pattern of tailgut cysts [3,8,9,12]. In adenocarcinoma arising in a tailgut cyst, elevation of a tumor marker such as CEA and CA19-9 is occasionally observed; in such cases, the tumor marker level can then be used to monitor their progression and recurrence [6,12,13].…”

Tailgut cyst, also called retrorectal hamartoma, is a rare congenital lesion and is usually located anterior to the sacrum and posterior to the rectum. We report a case of double tailgut cyst (presacral and precoccygeal hamartoma). A 62-yearold female visited the hospital complaining of anal pain and pressure in the perianal area for one month. Digital rectal examination revealed a round mass with hard consistency in the lateral and posterior part of rectum 5 cm from the anal verge. Pelvic magnetic resonance imaging showed two cystic and solid presacral masses (lateral and posterior part of rectum) compressing the rectum. The patient underwent surgical resection for pathologic diagnosis. At operation, two masses were located in the left presacral space without invasion to adjacent organs and soft tissue. Pathologic examination revealed double tailgut cysts without malignant transformation. A differential diagnosis of perirectal cystic hamartoma includes epidermal cysts, cystic teratomas, dermoid cysts, anal gland cysts, sarcoma and rectal duplications. Regional inflammatory process frequently complicates this lesion and perirectal fistula can develop. Tailgut cyst also has a malignancy potential, with development of adenocarcinomas. To establish a definite diagnosis and prevent complication, complete surgical resection is recommended.

“…On CT or MRI, tailgut cysts are visualized as retrorectal cystic masses that may extend into the ischioanal fossa. They are most frequently multilocular, often with a large central cyst and smaller peripheral or daughter cysts [9,10]. Signal intensity or attenuation is variable depending on cyst contents, and may be classically cystic, that is fluid-attenuation on CT or T1 hypointense and T2 hyperintense on MRI [9,11,12].…”

Tailgut cysts are congenital lesions that arise from the primitive hindgut in the true embryonic tail but fail to regress during gestation. These lesions are rare and more frequently encountered later in life and more commonly in women, and are the most common primary retrorectal tumor. Tailgut cysts may be asymptomatic or cause rectal bleeding, pain, or symptoms related to mass effect on the rectum or bladder. Pathologically, tailgut cysts are typically multilocular, lined with a variety of epithelial cell types, and are most frequently benign. Imaging is the linchpin of diagnosis due risks associated with biopsy. The purpose of this pictorial review is to present the spectrum of imaging findings associated with tailgut cysts on CT and MRI with focus on the use of advanced MRI and diffusion-weighted imaging. We present case examples of tailgut cysts, their CT and MR imaging findings, and diagnostic and management considerations.
