Retrorectal cysts are cystic lesions located in the retrorectal space and are a distinct subset of retrorectal tumours, which are often misdiagnosed due to their rarity and mimicry of symptoms caused by common diseases. We have described the presentation and management of four patients who were diagnosed with retrorectal cysts from a 10-year retrospective chart review at our institute, a tertiary care centre. In middle-aged women, the following should raise suspicion of retrorectal cyst: gastrointestinal or urinary obstructive features, mass or fullness palpable on the posterior wall on digital rectal examination, presacral dimple, perianal fistula and/or recurrent disease. Such features should prompt an MRI evaluation of the pelvis for definitive diagnosis.
