A rare case of bipartite parietal bone, an anatomical variant, was diagnosed in a male newborn via radiological assessment for a suspected skull fracture. The exact cause of this exceptional condition remains unknown.
Area of Science:
- Neonatal imaging
- Pediatric radiology
- Anatomical variants
Background:
- Bipartite parietal bone is a rare congenital anomaly where the parietal bone fails to fuse completely.
- It is often asymptomatic and discovered incidentally during radiological examinations for other conditions.
- Differential diagnosis includes skull fractures and other congenital skull abnormalities.
Observation:
- A male newborn, delivered at 37 weeks gestation, underwent radiological assessment due to a suspected skull fracture.
- Imaging revealed a bipartite parietal bone, an unusual anatomical variant.
- No other congenital anomalies were noted.
Findings:
- The primary finding was the incidental diagnosis of a bipartite parietal bone in a neonate.
- Radiological assessment confirmed the unfused nature of the parietal bone.
- Literature review highlighted the rarity and unclear etiology of this condition.
Implications:
- This case underscores the importance of recognizing bipartite parietal bone as a distinct entity from traumatic injuries in neonates.
- Accurate radiological interpretation is crucial for appropriate diagnosis and management.
- Further research into the genetic or developmental factors contributing to bipartite parietal bone may be warranted.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Sutures of the Skull
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...
Cranial Bones: Lateral View
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...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
