Abstract

Tail gut cysts are rare congenital lesions developing from postanal primitive gut remnants. They are mostly benign but carry a potential of malignant transformation, such as adenocarcinoma, neuroendocrine tumor, adenosquamous carcinoma, and pseudomyxoma peritonei. We present a 39-year-old woman with a neuroendocrine tumor arising within a tail gut cyst. She underwent complete resection in 2011. After 4 years, she was admitted with breast nodules, left proptosis, and gaze difficulties. Ga-DOTATATE PET/CT demonstrated extensive metastases including pelvic, lymph node, adrenal gland, bone, retro-orbital, cardiac, breast, skin, and subcutaneous metastases.

摘要

尾部肠囊肿是一种罕见的先天性病变，由肛后原始肠残余物发展而来。它们大多是良性的，但有恶性转化的潜力，如腺癌、神经内分泌肿瘤、腺鳞癌和腹膜假黏液瘤。我们报告一例 39 岁女性，患有源自尾部肠囊肿的神经内分泌肿瘤。她于 2011 年接受了完全切除术。4 年后，她因乳腺结节、左眼突出和眼球运动困难入院。Ga-DOTATATE PET/CT 显示广泛转移，包括骨盆、淋巴结、肾上腺、骨骼、眶后、心脏、乳腺、皮肤和皮下转移。
