The voluntary or accidental ingestion of foreign bodies organic or inorganic, rounded, blunt or sharp, is the second cause of upper endoscopy of urgency. It may cause complications, more sharp, producing esophageal perforation, secondarily retro-pharynx abscess, aorta-esophageal fistula or mediastinitis. Case of 17month-old infant, who presents odynophagia and drooling after intake of fish, is presented. In x-ray image opaque radio projected at the level of the cervical esophagus and endoscopic study of soft tissue edema, erosive image in upper esophageal sphincter and absence of foreign body was evident. New radiology noted similar to the initial image by what took place CT of neck confirming foreign body in left para-esophageal space image. He was cervicotomia with finding of edema at mucous-cutaneous level, pharyngeal retro pus, and fish bone on back side of esophagus. During postoperative period are decompensation hemodynamic and ventilatory, septic shock, and pharynx-cutaneous fistula managed conservatively. Starts by mouth after realization of esophagus radiology, which was normal, it emerges in apparent good condition. Conclusion: the visualization of the foreign body in endoscopic study does not rule out the possibility of esophageal penetration followed by abscess, fistula or mediastinitis.
