Cranial Bones: Superior and Posterior View

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,...

Area of Science:

Neuroimaging
Developmental Biology
Anatomy

Background:

The posterior fossa houses critical brain structures including the cerebellum and brainstem.
Malformations in these areas can lead to significant neurological deficits.

Purpose of the Study:

To review the normal anatomy of posterior fossa structures.
To discuss neuroimaging features of cerebellar and brainstem malformations.
To classify these malformations based on imaging patterns.

Main Methods:

Review of anatomical knowledge.
Analysis of neuroimaging characteristics.
Classification of malformations by imaging patterns.

Main Results:

Detailed description of normal posterior fossa anatomy.
Identification of characteristic neuroimaging features for various malformations.
A classification system for posterior fossa malformations: predominantly cerebellar, cerebellar and brainstem, and predominantly brainstem.

Conclusions:

Neuroimaging plays a crucial role in diagnosing and classifying posterior fossa malformations.
The proposed classification aids in understanding the spectrum of these congenital abnormalities.
