Tetanus is a rare and lethal disease that results from exposure to exotoxins produced by Clostridium tetani. A seven year-old-male refugee who had not been vaccinated in early childhood was admitted to the hospital with generalized muscle spasm and pain. The anamnesis taken from the patient revealed that he had suffered from nail injury after falling down a week ago and didn’t take any medical care. He was diagnosed with tetanus and admitted to the intensive care unit. He was given tetanus vaccine and tetanus immunoglobulins. Penicillin treatment was started. The wound was surgically debrided. The patient was intubated due to increased muscle spasms and respiratory distress. After that the patient who went into cardiac arrest was necessitated cardiopulmonary resuscitation. In the follow-up of the patient, acute renal failure and multiple organ failure accompanied by disseminated intravascular coagulation developed and exitus followed. In conclusion, the history of vaccination should be questioned in patients presenting with central nervous system findings especially after injuries due to the increase in the incidence in our country, and tetanus should definitely be considered in the differential diagnosis.
