Summary
Pycnodysostosis can mimic skull fractures after head trauma. This case shows a child recovered with conservative care, emphasizing diagnostic challenges in distinguishing acute injury from chronic bone issues.
Area of Science:
- Pediatric Radiology
- Skeletal Dysplasias
- Emergency Medicine
Background:
- Pycnodysostosis is a rare genetic disorder characterized by osteosclerosis and bone fragility.
- Patients with pycnodysostosis are at increased risk for fractures and other skeletal abnormalities.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
