巨细胞动脉炎（GCA）是一种中至大血管炎，具有广泛的疾病表现，包括听力损失。除了组织组织学外，临床症状和血管影像学的相关性对于GCA的明确诊断是最佳的。在这里，我们描述了一个极其罕见的GCA伴有听力损失和中耳炎的病例，其中在3-特斯拉下获得对比增强的3d磁共振成像，以评估颅动脉的炎症受累。自旋回波成像显示左侧脑膜内侧动脉和颞浅动脉壁增厚和对比增强。同时，梯度回声成像显示左侧输卵管和咽鼓管强烈强化，与乳突腔无强化积液相关。结果提示颞骨动脉炎症广泛分布，包括小血管炎，可引起颅脑GCA的耳科表现。
Giant cell arteritis (GCA), a medium to large-vessel vasculitis, has a broad spectrum of disease manifestations, including hearing loss. In addition to tissue histology, clinical correlation of symptoms and vascular imaging is optimal for a definitive diagnosis of GCA. Here, we describe an extremely rare case of GCA with hearing loss and otitis media, wherein contrast-enhanced 3 D-magnetic resonance imaging was acquired at 3-Tesla for assessment of inflammatory involvement of cranial arteries. Spin-echo imaging demonstrated mural thickening and contrast enhancement of the medial meningeal artery in addition to the superficial temporal artery on the left side. Simultaneously, gradient-echo imaging revealed intense enhancement in the fallopian canal and eustachian tube on the left side, which was associated with non-enhanced effusion in the mastoid cavity. The findings suggest a broad distribution of arterial inflammation in the temporal bone, including small vessel vasculitis, which may cause otologic manifestations in cranial GCA.
