<p>Retropharyngeal abscess is a common deep neck space infection in the early paediatric age group, usually polymicrobial, following upper respiratory tract infections. In children, it is usually due to suppurative changes in the retropharyngeal nodes which drain the nasopharynx, oropharynx and tonsils. Its clinical features are like other deep neck space infections including fever, odynophagia, reduced oral intake and neck stiffness. If untreated promptly, as the disease progresses, the area of suppuration may expand locally causing involvement of its adjacent structures, including inflammatory torticollis which is more commonly on the ipsilateral side. Early imaging and diagnosis is important to guide the decision for the treatment modality to prevent further complication and ensure good outcome. We hereby present a case of an 8-year-old boy, who has left-sided retropharyngeal abscess complicated with left cervical lymphadenitis, ipsilateral internal jugular vein thrombosis and unusual contralateral torticollis, who responded well to inpatient intravenous antibiotics and surgical drainage.</p>
