Learning objectives
To describe basic anatomy of the skull base
To review common pathologies of the skull base
To learn best imaging modalities to display skull base pathologies
Background
The skull base is a complex region with multiple compartments and components.
Diseases of the skull base are not easily evaluated clinically and imaging is critical for the diagnosis.
Radiologist should be familiar with the complex anatomy and common pathologies of the skull base for reaching appropriate differential diagnosis.
We review the radiological anatomy and common pathologies of the skull base with a quiz to make learning easy and fun.
Enjoy!
Findings and procedure details
Answer 1: C The basiocciput
The bones of skull base are formed by endochondral ossification.
The bones of calvaria and face are formed by intramembranous ossification.
The occipital bone has interparietal,
supraoccipital and exoccipital ossification centers.
The interparietal and the supraoccipital parts of the occipital bone are separated by the mendosal suture,
that disappears during the first year of the life.
The most upper part of the occipital bone (interparietal) shows intramembranous ossification whereas the rest of the occipital bone shows endochondral ossification.
Answer 2:...
Conclusion
Knowledge of the complex anatomy and the differential diagnosis of common lesions are very important for evaluating the skull base pathologies.
We hope the quizis informative and fun.
Thank you!
