BACKGROUND
This report detailed an extremely rare location of an endodermal cyst. Such location of the tumor can pose radiological confusion and a therapeutic dilemma. However, when identified, it can be a pleasant surprise for the surgeon and provide the possibility of a symptom-free long life for the patient.
OBSERVATIONS
This report discussed two young patients who presented with relatively short-duration reports of ataxia and diplopia. Investigations revealed intraaxial brainstem lesion. During surgery, thick, pus-like fluid was evacuated and part of a wall was resected. Histology revealed that the lesion was an endodermal cyst. Both patients are well and are lesion- and symptom-free for 24 and 72 months.
LESSONS
Endodermal cysts are some of the few long-standing and benign intraaxial brainstem lesions.
背景
本报告详细介绍了一例极为罕见部位的内胚层囊肿。肿瘤的这种位置可能会造成放射学上的混淆以及治疗上的两难困境。然而，一旦确诊，对外科医生来说可能是个惊喜，并为患者提供长期无症状生存的可能性。
观察结果
本报告讨论了两名年轻患者，他们出现共济失调和复视的时间相对较短。检查发现轴内脑干病变。手术过程中抽出了浓稠的脓性液体，并切除了部分囊壁。组织学检查显示该病变为内胚层囊肿。两名患者情况良好，分别在24个月和72个月时无病变且无症状。
经验教训
内胚层囊肿是少数几种长期存在的轴内脑干良性病变。
