“…Rare cases of associated thin calcifications have been reported in dermoid cysts. If there is any complication such as infection, the cyst may be thick-walled with surrounding inflammatory tissue modifications [1][2][3]. MRI shows a well-defined, thin-walled, hypointense lesion on T1-weighted images and a homogeneous, hyperintense lesion on T2-weighted images.…”

“…MRI shows a well-defined, thin-walled, hypointense lesion on T1-weighted images and a homogeneous, hyperintense lesion on T2-weighted images. The high signal intensity on T1-weighted images is likely to be due to the fatty content of the dermoid cyst [1,2]. Preoperative biopsy for cystic masses within the pelvis is not considered essential because it may not assist in proper lesion differentiation and may lead to spillage of cells into the peritoneal cavity and seeding of the biopsy tract [11].…”

“…Other cystic lesions such as cystic sacrococygeal teratoma, anterior sacral meningocele, anal duct cyst, necrotic rectal leiomyosarcoma, extraperitoneal adenomucinosis, cystic lymphangioma, pyogenic abcess, neurogenic cyst, necrotic sacral chordoma are also included in the differential diagnosis [2,3,6,7]. Because of the risks of recurrence, malignant degeneration and chronic infection, the treatment of choice for retrorectal dermoid cysts is complete surgical excision [1][2][3]. Cystic excision could be performed via the abdominal or the posterior approach, or using a combined technique.…”

“…Histopathologically, retrorectal cysts can be differentiated from epidermoid cysts by gross as well as microscopic analysis because they contain skin appendages (hair follicles, sweat glands, tooth buds). The cysts are lined with a stratified squamous epithelium and filled with dense muddy or fatty material [1,4,14].…”

“…The rarity of these tumors in adults and their nonspecific clinical presentations often hamper diagnosis and lead to misinterpretations. Although rare in occurrence, a wide variety of lesions being inflammatory, neoplastic or congenital in origin can be found [1,2]. Accurate diagnosis, localization, and characterization of retrorectal lesions will affect surgical management.…”

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.
