Abstract

Metastatic adenocarcinoma mimicking meningioma is rare; and any metastatic lesion masquerading as an en plaque meningioma is extremely rare. We report the case of a 50-year-old female, who presented with headache and left hemiparesis for 1 month and on imaging showed a dural-based enhancing mass along the right hemisphere. The patient was operated with a working diagnosis of en plaque meningioma. Histopathology revealed metastatic adenocarcinoma. This report highlights an unusual radiological presentation of a metastatic lesion as dural based en plaque variety. Metastasis should be borne in mind for any en plaque lesion with rapid clinical progression.

摘要

转移性腺癌伪装成脑膜瘤极为罕见；而任何伪装成扁平状脑膜瘤的转移瘤更是极其罕见。我们报告一例50岁女性患者，她因头痛和左侧偏瘫1个月就诊，影像学检查显示右半球有一个硬膜下强化肿块。患者接受手术，术前诊断为扁平状脑膜瘤。组织病理学检查显示为转移性腺癌。本报告强调了转移瘤一种不寻常的影像学表现，即呈硬膜下扁平状。对于任何临床进展迅速的扁平状病变，都应考虑转移的可能。
