Oesophageal foreign bodies (OFBs) are a relatively common emergency in young children. OFBs are complicated by significant morbidity and mortality because their ingestion often occurs without witnesses, leading to a delay in diagnosis and treatment. We report an occult OFB in an 11-month-old infant who initially presented without any specific respiratory symptoms, mimicking a respiratory infection. Worsening of the patient's cough, which did not show any improvement, despite treatment, and progressive onset of gastrointestinal manifestations (dysphagia, vomiting, and drooling) led to the diagnosis of an OFB (metallic spring). The complex and long-term clinical course of the patient highlights the need of promptly recognizing the presence of an occult OFB. This is because rapid diagnosis and treatment are essential for preventing severe and sometimes irreversible complications.
