一例无任何易感因素的鼻粘膜炎：一种罕见的表现
A Case of Nasal Myiasis Without Any Predisposing Factors: An Uncommon Presentation.
摘要(中文译文)
鼻蝇蛆病是一种累及鼻腔的少见人类寄生虫病。在耳鼻咽喉科，蝇蛆病多以耳蝇蛆病和口腔蝇蛆病的形式出现，而作为鼻蝇蛆病发生则较为罕见。该病通常影响卫生条件差、患有慢性疾病或免疫功能低下的个体。在免疫功能正常个体中发生的病例极为罕见，且可带来诊断挑战。我们报告一例32岁免疫功能正常女性，表现为经鼻孔自行排出小幼虫。内镜检查时在双侧鼻腔均观察到活幼虫。寄生虫学分析证实为羊狂蝇（Oestrus ovis）幼虫。未发现潜在的免疫缺陷或易感因素。影像学显示双侧上颌窦炎伴前组筛窦炎。未进行手术取出，患者仅接受口服阿苯达唑治疗。据我们所知，免疫功能正常宿主中鼻蝇蛆病的报道仅见少数几例，凸显了该表现的罕见性。本报告强调了在鼻腔症状的鉴别诊断中考虑鼻蝇蛆病的重要性，即使在免疫功能正常的个体中亦是如此。早期识别和及时处理对于预防并发症和确保患者获得最佳结局至关重要。
Abstract
Nasal myiasis is an uncommon human parasitic disease affecting the nasal cavity. In otolaryngology, myiasis is mostly encountered as aural myiasis and oral myiasis, but occurs rarely as nasal myiasis. It typically affects individuals with poor hygiene, chronic illness, or immunosuppression. Cases in immunocompetent individuals are exceptional and can present diagnostic challenges. We report the case of a 32-year-old immunocompetent female who presented with the spontaneous expulsion of small larvae through the nostrils. Live larvae were observed in both nasal cavities during endoscopic examination. Parasitological analysis confirmed the presence of Oestrus ovis larvae. No underlying immunodeficiency or predisposing condition was identified. Imaging revealed bilateral maxillary sinusitis with anterior ethmoiditis. No surgical removal was performed, and the patient received only oral albendazole. To our knowledge, only a few cases of nasal myiasis have been reported in immunocompetent hosts, highlighting the rarity of this presentation. This report underscores the importance of considering nasal myiasis in the differential diagnosis of nasal symptoms, even in immunocompetent individuals. Early recognition and prompt management are essential for preventing complications and ensuring optimal patient outcomes.
