Open surgical treatment for giant presacral tailgut cyst - a case report

Tailgut cyst is an exceedingly rare congenital anomaly originating from embryonic remnants of the tailgut. Owing to its asymptomatic nature in the early stages, it is prone to clinical misdiagnosis. We present a case of a 55-year-old female with initial symptoms manifesting as sacrococcygeal pain. Magnetic resonance imaging (MRI) revealed a multilocular cystic lesion, prompting preoperative suspicion of an enormous tailgut cyst. Following a comprehensive assessment, an open posterior approach with coccygectomy was chosen, proving to be a safe and effective surgical technique, particularly for large, low-lying tailgut cysts.
