Abstract

Craniopharyngiomas comprise approximately 1-3% of all intracranial tumors and arise from squamous epithelial rests along remnants of Rathke's cleft. They have bimodal age distribution. The ectopic sites reported are the nasopharynx, sphenoid bone, pineal region, cerebellopontine angle and third ventricle. We report a case of ectopic craniopharyngioma in the Foramen of Monro with restricted diffusion, which have is an unusual feature, not commonly reported and is a potential pitfall.

摘要

颅咽管瘤约占所有颅内肿瘤的1%-3%，起源于沿拉特克裂残余的鳞状上皮残余物。它们具有双峰年龄分布。报道的异位部位有鼻咽、蝶骨、松果体区、桥小脑角和第三脑室。我们报告一例发生于孟氏孔的异位颅咽管瘤，其具有扩散受限的表现，这是一个不常见的特征，鲜有报道，且是一个潜在的陷阱。
