A 38-year-old man with a right frontal lobe cyst was treated by endoscopic cystoventriculostomy in 1998. Cyst capsule histology revealed surprisingly an endodermal cyst. The patient was reoperated for cyst expansion by endoscopic re-cystoventriculostomy in 2005. In 2007, the patient suffered from brain abscess formation within the cyst which was punctured. The history was positive for a dental infection. In 2008, a recurrent brain abscess in the cyst occurred. The cyst was completely resected. There was no history of trauma or sinusitis. In all, endodermal cysts may mimic a paraxial arachnoid cyst. It may predispose for recurrent brain abscess formation - especially due to bacteraemia. This report confirms earlier presentations that endodermal cysts should be resected, and endoscopic cyst opening is not sufficient.
一名38岁的男性，患有右侧额叶囊肿，于1998年接受了内镜下囊肿脑室造瘘术治疗。囊肿包膜组织学检查令人惊讶地发现是一个内胚层囊肿。该患者于2005年因囊肿扩大再次接受手术，行内镜下再次囊肿脑室造瘘术。2007年，患者囊肿内形成脑脓肿并进行了穿刺。病史显示有牙齿感染。2008年，囊肿内再次发生脑脓肿。囊肿被完全切除。患者无外伤或鼻窦炎病史。总之，内胚层囊肿可能类似于近轴蛛网膜囊肿。它可能易引发复发性脑脓肿形成——尤其是由于菌血症。本报告证实了早期的观点，即内胚层囊肿应行切除术，单纯内镜下囊肿开窗术并不足够。
