A 55-year-old healthy female without trauma history visited our hospital for rapidly progressive enlarging right side painful neck mass within 5 days and also with comorbid House-Brackmann Grade V facial palsy for 2 days. Magnetic resonance imaging showed heterogenous mass derived from parotid to parapharyngeal space. Much blood clot could be observed at exploratory operation. Only inflammatory change, but not tumor, was mentioned in pathology report. Facial palsy was kept stationary in Grade III from postoperative 6 months.
