“…On MR imaging, the lesion signal depends on its content (serous, mucinous or purulent), but it is usually hypointense on T1-weighted images, with no change after fat suppression, and hyperintense on T2-weighted images [14,17]. However, an intermediate signal on T1-weighted images with or without hyperintense foci, as in our case, has been reported [5,15,16].…”

CT and MR findings of a retrorectal cystic hamartoma confused with an adnexal mass on ultrasound

We describe the imaging features of a tailgut cyst mistaken for an adnexal mass. A pelvic ultrasound in a 28-year-old woman showed a 10-cm hypoechoic left pelvic mass. Having not seen the left ovary, the radiologist concluded that the mass was an endometrioma. CT disclosed a retrorectal cystic lesion with wall calcifications and internal septa. MR confirmed the extra-ovarian location of the tumor, which was hyperintense on T2-weighted images and had an intermediate signal on T1-weighted images. Surgery revealed a retrorectal cystic hamartoma. Radiological diagnosis of a tailgut cyst requires first correct localization of the tumor and then differentiation from other retrorectal masses.

Abstract Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomography (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space.

“…The imaging features of the dermoid cyst (plain radiography, ultrasonography, CT, and MRI) are limited. Plain radiography uncommonly shows sacrococcygeal abnormalities such as a bone defect in association with dermoid, tailgut and neuroenteric cysts [6,[8][9][10]. A communication between the cyst and the anorectal lumen may be demonstrated during a barium enema examination.…”

Background: Retrorectal cyst are rare lesions. Their clinical presentation is nonspecific, thus hampering their detection and frequently leading to misdiagnosis. According to their origin and histopathologic features, rectorectal cysts are classified as epidermoid, dermoid, enteric (tailgut cysts and cystic rectal duplication), and neurenteric cysts. Here we present the clinical, radiological and surgical findings in a case with a retrorectal dermoid cyst. Case Report: A 47-year-old male patient presented with rectal fullness and pain. MRI and CT studies revealed a noncalcified, unilocular, cystic mass lesion with well-defined borders. On MRI, self-contained fat spheres were detected inside the cyst. The cyst was excised completely by laparotomy. Pathological assessment revealed a dermoid cyst. The patient’s postoperative period was uneventful, and there was no recurrence during a 2-year follow-up. Conclusion: Complete surgical excision is indicated to establish the diagnosis and avoid complications of retrorectal cysts.
