Malignant otitis externa (MOE) is an aggressive but benign entity which evolves into skull base osteomyelitis. An 81-year-old female patient was admitted for left hemiparesis and homonymous hemianopia. She complained of headache radiating to the right cervical area. A recent history of recurrent otitis media was present. Head and neck imaging showed an ischemic infarction (right temporo-occipital) and a parapharyngeal soft tissue mass originating in an external and medial ear infection. Culture samples revealed infection leading to the diagnosis of Malignant otitis externa (MOE). Parenteral antibacterial therapy and hyperbaric oxygen therapy resulted in improvement.
Malignant otitis externa is an aggressive and life-threatening disease which must be identified early and treated promptly for therapeutic success.Although starting as an outer ear infection (typically caused by ) local spread can involve noble head and neck structures leading to variable signs and symptoms.Modern imaging techniques can help define structure involvement (MRI) and may help identify disease activity and prognosis (nuclear medicine).
恶性外耳道炎（MOE）是一种侵袭性但良性的疾病，可发展为颅底骨髓炎。一名81岁女性患者因左侧偏瘫和同向性偏盲入院。她主诉头痛放射至右侧颈部区域。近期有复发性中耳炎病史。头颈部影像学检查显示缺血性梗死（右颞枕部）以及起源于耳部内外感染的咽旁软组织肿块。培养样本显示感染，从而确诊为恶性外耳道炎（MOE）。肠外抗菌治疗和高压氧治疗使病情得到改善。
恶性外耳道炎是一种侵袭性且危及生命的疾病，必须早期识别并及时治疗才能取得治疗成功。虽然它起始于外耳感染（通常由……引起），但局部扩散可累及头颈部重要结构，导致各种体征和症状。现代影像学技术有助于明确结构受累情况（MRI），并可能有助于识别疾病活动度和预后（核医学）。
