Tailgut Cyst (Retrorectal Cystic Hamartoma) - A Rare Retrorectal Lesion

BACKGROUND - Tailgut cysts or retrorectal cystic hamartomas are unusual cystic lesions, typically found in the retrorectal (presacral) space. Due to its rarity, diagnosis is often delayed. They can present as painless masses or with symptoms of mass effect or complications such as infection and recurrence. Complete surgical excision is the treatment of choice as malignant transformation within the cyst, although atypical, can occur. AIM AND METHODS - Here, we present a case of a tail gut cyst which illustrates the diagnosis and management. CONCLUSION - Tailgut cysts are rare lesions with variable clinical presentation. It should be kept in mind as a differential diagnosis for a retrorectal mass. CT or MRI is the investigation of choice. Complete surgical excision is indicated.
