Magnetic resonance (MR) imaging is crucial for diagnosing skull base lesions, offering superior soft tissue detail. This article details the skull base anatomy relevant for MR imaging evaluation of these complex conditions.
Area of Science:
- Radiology
- Neuroimaging
- Skull Base Anatomy
Background:
- Accurate diagnosis and treatment of skull base lesions depend on understanding complex skull base anatomy.
- Direct evaluation of the skull base is not possible, making imaging techniques essential for diagnosis and management.
- Computed tomography (CT) excels at bony detail, while magnetic resonance (MR) imaging provides superior soft tissue contrast.
Purpose of the Study:
- To focus on the radiologic anatomy of the skull base.
- To provide information pertinent to magnetic resonance (MR) imaging evaluation of skull base lesions.
Main Methods:
- Review of skull base anatomy with an emphasis on magnetic resonance (MR) imaging features.
- Integration of computed tomography (CT) and MR imaging findings for comprehensive evaluation.
Main Results:
- Magnetic resonance (MR) imaging offers detailed visualization of soft tissues, meninges, brain parenchyma, and bone marrow.
- Combined CT and MR imaging approaches are frequently employed for evaluating skull base lesions.
Conclusions:
- A thorough understanding of skull base anatomy visualized through MR imaging is vital for accurate diagnosis.
- This article serves as a guide to the radiologic anatomy relevant for MR imaging in skull base disease.

01:14Cranial 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,...
01:27Cranial 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...

01:22Sutures 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...
