A dirofilariosis – fonalféreg-fertőzés – ritka esete fej-nyak sebészeti területen

Abstract: Dirofilariasis refers to an infection caused by a specific parasitic roundworm. Dirofilaria repens – transmitted by mosquito bites – accounts for most human cases. The parasite forms a subcutaneous mass called cutaneous dirofilariasis near the original site of intrusion. The incidence of human infections shows an increasing tendency. We report a case of a 35-year-old woman presenting with three-week history of a painful swelling in the temporal region. The initial diagnostic work-up revealed a roundworm embedded in the subcutaneous fat tissue and temporal muscle. Differential diagnosis included erysipelas, herpes zoster, temporal arteritis. The final diagnosis of helminthiasis was established by ultrasound examination. A multidisciplinary consultation including infectious diseases specialist suggested surgical removal of the lesion. The microbiological examination of the specimen confirmed the presence of a female Dirofilaria repens. Orv Hetil. 2018; 159(45): 1844–1847.
