[Tailgut cysts].
Retrorectal cystic hamartomas (tailgut cysts) are rare congenital lesions thought to arise from remnants of the embryonic postanal gut. They predominantly occur as asymptomatic retrorectal multicystic masses in women. The treatment of choice is by complete surgical excision. The most important complications of these cysts are infection with a secondary fistula and malignant degeneration. The differential diagnosis includes a wide variety of conditions that occur in the retrorectal space. In this article, 3 cases showing different surgical technical aspects of treatment are presented. In addition, the aetiopathogenic features and histopathological appearance, clinical presentation and complications, imaging features and differential diagnosis of tailgut cysts are described.
