A localized, cystic, "blue ear drum" (idiopathic hymotympanum) mimicking a middle ear vascular tumor occurred in a 12-year-old boy. This lesion must be included in the differential diagnosis of suspected vascular mass of the middle ear. A history of eustachian tube dysfunction should be sought. Physical examination is usually not diagnostic, and a full radiologic evaluation is essential in order to rule out a high jugular bulb, an ectopic carotid artery, or a glomus tumor.
一名12岁男孩出现了一种局限性、囊性的“蓝鼓膜”（特发性鼓室积液），酷似中耳血管性肿瘤。这种病变必须列入中耳疑似血管性肿块的鉴别诊断范围。应了解咽鼓管功能障碍病史。体格检查通常无法确诊，为排除高位颈静脉球、异位颈动脉或颈静脉球体瘤，全面的影像学评估至关重要。
