A Rare Clinical Case Causing Dystocia and Lumbago: Retrorectal Dermoid Cyst

Retrorectal space is area of loose connective tissue bound anteriorly by the deep layers of the rectal fascia, posteriorly by the presacral fascia covering the sacrum, and bilaterally by the rectum, ureters, and iliac vessels. Peritoneal reflexion marks upper border, and retrosacral fascia (Waldeyer’s fascia) forms lower border. Retrorectal mass is rarely seen, with incidence of 1/40,000.[1,2] Mass lesion of this region is generally benign, though may at times demonstrate malignant characteristics.
