Insights

A bipartite parietal bone, a rare skull condition, was diagnosed in an infant with an asymmetrical head. This finding is associated with deformational plagiocephaly, a common cause of infant head shape differences.

Area of Science:

  • Pediatric Radiology
  • Developmental Biology
  • Craniofacial Surgery

Background:

  • Deformational plagiocephaly is a common condition in infants, characterized by asymmetrical head shape.
  • Accurate diagnosis is crucial for appropriate management and to rule out underlying skeletal abnormalities.

Observation:

  • An infant presented with asymmetrical head shape, exhibiting clinical features consistent with deformational plagiocephaly.
  • Three-dimensional computed tomography (3D CT) imaging was utilized for detailed craniofacial assessment.

Findings:

  • The 3D CT imaging revealed a bipartite parietal bone, a rare congenital anomaly where the parietal bone fails to fully fuse.
  • This case highlights a potential, though uncommon, underlying cause for plagiocephaly.

Implications:

  • Diagnosing bipartite parietal bone in infants with plagiocephaly is important for understanding etiology.
  • Further research into the prevalence and specific etiologies of bipartite parietal bone is warranted.
  • This finding may influence management strategies for complex cases of infant head asymmetry.

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
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,...

Cranial 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...

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Prosopagnosia01:24

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...

Cerebrum: Anatomical Overview I

The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...
