OBJECTIVE
We report three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging findings in a patient with relapsing polychondritis.
METHOD
Case report.
RESULT
A 76-year-old woman initially presented with bilateral auricular swelling together with dyspnoea. Three months later, she experienced left hearing loss and recurrent vertigo. A biopsy of the auricle was performed and relapsing polychondritis was diagnosed. The patient underwent three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging 4 hours after intravenous injection of a standard dose of gadolinium. Gadolinium enhancement was visible throughout the vestibule and the endolymphatic space could not be visualised, suggesting breakdown of the blood-labyrinth barrier.
CONCLUSION
This is the first radiological report to demonstrate breakdown of the blood-labyrinth barrier in a case of relapsing polychondritis with inner ear impairment.
目的
我们报告了1例复发性多软骨炎患者的三维液体衰减反转恢复磁共振成像结果。
方法
病例报告。
结果
一名76岁女性最初表现为双侧耳廓肿胀伴呼吸困难。3个月后，她出现左耳听力丧失和反复眩晕。对耳廓进行活检，诊断为复发性多软骨炎。患者在静脉注射标准剂量钆喷酸葡胺4小时后接受了三维液体衰减反转恢复磁共振成像检查。在前庭可见钆增强，内淋巴间隙无法显示，提示血迷路屏障破坏。
结论
这是第一份关于复发性多软骨炎伴内耳损伤病例血迷路屏障破坏的影像学报告。
