We reported a case of adult Drosophila melanogaster parasitized in nasal cavity of a 81-year-old woman who was living in Xuancheng City, Anhui Province now. She was admitted for treatment of cerebral infarction and water accumulation in the lungs in 2014 June. The patient was also suffering from secretory otitis media, a history of hypertension and heart stents were placed in 2007. A foreign body was found in the left nasal cavity during the preoperative examination process, and then the part of the inflammatory tissue was removed through the nasal endoscopy, and sent to our department for identification.
