Nowadays, button battery ingestion accounts for one of the common foreign body ingestions among pediatric population. Unexpected manifestations in this setting, particularly after late removal, are confusing and might be misleading and postpone the proper management. We report a case of button battery ingestion in a 10-month-old boy who was primarily considered uncomplicated. However, he was readmitted with neck stiffness, which later turned to be due to spondylodiscitis. Based on this report, we strongly recommend considering spondylodiscitis as a late but serious complication of button battery ingestion in any patient who presents with restricted neck movement following foreign body ingestion.
