Tail-gut cyst

Tailgut cyst: from differential diagnosis to surgical resection-case report and literature review

Tailgut cyst is a rare tumor originating from the embryonic remnant located in the retrorectal space. The diagnosis is usually incidental duse to the absence of symptoms. When present, they are nonspecific, such as abdominal pain, dysuria and tenesmus. Imaging tests are a great help in the diagnosis and surgical planning. The standard treatment is resection, which the surgeon must perform to avoid future complications, such as malignancy. We present a case of tailgut cyst in a young patient with prior pilonidal cyst excision, subsequently submitted to surgical resection, to share our experience with a rare case, with few reports in the literature.

A Tailgut Cyst Diagnosed by Endoscopic Ultrasound-Guided Fine-Needle Aspiration

Tailgut cysts are rare developmental cysts. Surgery has been the primary method of diagnosis and treatment of these cysts, but endoscopic ultrasound (EUS) has recently been used to establish diagnosis. Only 2 cases of tailgut cyst diagnosed by EUS-guided FNA have been reported. We present a woman in her fourth decade who presented for evaluation of perirectal mass. EUS-guided fine-needle aspiration (FNA) helped establish the diagnosis of tailgut cyst. The patient opted for observation rather than surgery.
