Background: Foreign body invasion of the brain can cause traumatic brain injury with severe complications. In most cases, it can be a late diagnosis. We reported here a case of traumatic brain injury from a foreign body invasion and, after being invested patient was taken for emergency craniotomy with successfully removal of foreign body. Case Report: A 12 yr. old boy developed a headache and vomiting for 2 days after his head was hit on a bundle of sticks 2 days back while riding a cycle. On examination, the patient was conscious oriented. No deficit. Diagnosis was confirmed after an emergency CT was taken that showed a right temporal bone fracture with a piercing foreign body into the right temporal lobe. Right temporal craniotomy and removal of a foreign wooden body was done. The patient was managed with IV antibiotics and anticonvulsants. Post-op brain CT was done and showed no evidence of foreign body. The patient was hospitalized for days and recovered with no sequelae. Conclusion: Penetrating brain injuries are very serious and have life-threatening complications. Precautious action should be taken as soon as possible with investigations and imaging. Prognosis depends on severity of injury and involvement of brain structures. Early diagnosis with immediate procedure always has favorable outcomes.
