Abstract

Malignant otitis externa is a severe, rare infective condition of the external auditory canal and skull base. The diagnosis is generally made from a range of clinical, laboratory, and imaging findings. Technetium 99m methylene diphosphonate bone scintigraphy is known to detect osteomyelitis earlier than computed tomography. The authors present a patient with bilateral malignant otitis externa where the extent of skull base involvement was determined on 3-phase bone scintigraphy with single photon emission computed tomography/computed tomography.

摘要

恶性外耳炎是一种严重且罕见的外耳道和颅底感染性疾病。其诊断通常基于一系列临床、实验室和影像学检查结果。锝 99m 亚甲基二膦酸盐骨扫描比计算机断层扫描更早地发现骨髓炎。作者介绍了一位双侧恶性外耳炎患者，其颅底受累范围通过单光子发射计算机断层扫描/计算机断层扫描的三相骨扫描确定。
