An inflammatory collagenopathy of infancy characterized by subperiosteal bone hyperplasia is known as infantile cortical hyperostosis (ICH) or Caffey disease. A 10-day male infant presented to the hospital with leg swelling, excessive crying, and irritability since birth. He was born with the swallowed part of his tibia bone. The X-ray suggested hyperostosis of the bilateral tibia bone involving the anterior cortex, which is more prominent on the right side. The infant was clinically monitored and treated and discharged after the swelling was reduced. Again, he was admitted to the hospital at 10 weeks of life, and a similar thickening appeared on his left tibia. He was administered analgesics and non-steroidal anti-inflammatory drugs (NSAIDs) and discharged under a follow-up schedule. The infant was monitored in the pediatric ward for the next seven days. The swelling and pain completely subsided one and a half weeks after hospitalization, and continued follow-up was suggested until the complete correction of the disease on an outpatient basis. This disease must be recognized and understood, and the clinical-radiological correlation is significant.
