Growing skull fracture: A case report

An 18-day-old male baby who had fallen from his mothers arms and hit his head on the floor was admitted to our hospital. On admission, the patient was crying, but no weakness was noted in the extremities. A small fluctuant protrusion was visible in the right parietal region. The plain skull X-ray film revealed a wide linear fracture in, the parietal bone. Computed tomography (CT) showed swelling of the right hemisphere and a traumatic subarachnoid hemorrhage. At 41 days old, the subcutaneous fluid collection had increased in volume and the width of the linear skull fracture was also enlarged as shown on the X-ray film. CT and magnetic resonance imaging (MRI) revealed a large cyst herniating through the wide parietal bone defect. There was also an enlarged right lateral ventricle and a torn dural margin in the brain. The cranioplasty with dural plasty was performed on the 43th day of ago under the diagnosis of growing skull fracture of the right parietal bone. The postoperative course was uneventful, without seizure or weakness. In order to diagnose growing skull fracture, especially to show the relationship between the fracture, torn dura matter, the ventricle and the confused brain, MRI was very helpful combined with CT and plain skull X-rays. Cranioplasty with dural repair was considered the essential procedure for the treatment of such growing skull fractures.
