Abstract

Hypertrophic pachymeningitis refers to linear or nodular thickening of the dura mater covering the brain and spinal cord following various inflammatory/infective processes. Usually, magnetic resonance imaging brain shows uniform thickening with enhancement of involved meninges. Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) findings of pachymeningitis are rarely reported in literature. We describe the PET/CT findings of a patient with hypertrophic pachymeningitis involving the bilateral supraorbital regions depicting as "eyebrows" on brain maximum intensity projection image.

摘要

肥厚性硬脑膜炎是指在各种炎症/感染性过程后，覆盖脑和脊髓的硬脑膜出现线性或结节状增厚。通常，脑部磁共振成像显示受累脑膜均匀增厚并强化。关于肥厚性硬脑膜炎的氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（PET/CT）表现，文献中鲜有报道。我们描述了一例累及双侧眶上区域的肥厚性硬脑膜炎患者的PET/CT表现，在脑部最大强度投影图像上呈现为“眉毛”状。
