A 78-year-old man presented to the accident and emergency department with acute abdominal pain. A CT scan done to investigate the pain showed an intra-abdominal abscess medial to the caecum and an incidental exophytic lesion in the gall bladder. This was excised during surgery and sent for histological examination. Histology showed a ciliated foregut cyst of the gall bladder. A literature review revealed that this was the 13th case worldwide, as ciliated foregut cysts are usually found either above the diaphragm or in the liver. It was also the largest cyst described, with 45 mm diameter. So far none of these cysts found in the gall bladder have shown malignant transformation, though those found in the liver have been known to become malignant. Due to histological similarity, excision of ciliated foregut cysts of the gall bladder should be considered as there is still a risk of malignant transformation.
一名78岁男性因急性腹痛被送往急诊室。为查明疼痛原因而进行的CT扫描显示，盲肠内侧有腹腔内脓肿，胆囊内有一个偶然发现的外生性病变。该病变在手术中被切除并送去做组织学检查。组织学检查显示为胆囊的纤毛前肠囊肿。文献综述显示，这是全球第13例此类病例，因为纤毛前肠囊肿通常见于膈肌上方或肝脏。这也是所描述的最大囊肿，直径达45毫米。尽管已知肝脏中的纤毛前肠囊肿会发生恶变，但迄今为止在胆囊中发现的这些囊肿均未显示恶变。由于组织学相似性，鉴于仍有恶变风险，应考虑切除胆囊的纤毛前肠囊肿。
