Lemierre's syndrome is a rare, life-threatening condition characterized by septic thrombophlebitis of the internal jugular vein, typically following oropharyngeal infection. We report a rare case in a 10-year-old girl presenting with recurrent sore throat and progressive left-sided neck swelling. Ultrasound served as a critical first-line imaging tool, revealing a hypoechoic mass compressing the internal jugular vein. The diagnosis was confirmed by contrast-enhanced CT and fine-needle aspiration, and the patient recovered following antibiotic therapy. This case underscores the rarity of Lemierre's syndrome in pediatric patients and highlights the utility of ultrasound for early detection and timely intervention in atypical presentations.
