Summary
Partial ossification of the falx cerebri is a common incidental finding on brain CT and MRI scans. Differentiating it from other lesions like meningioma is usually straightforward.
Area of Science:
- Neuroradiology
- Neuroanatomy
- Incidental Findings
Background:
- Partial ossification of the falx cerebri is an anatomical variation.
- It is frequently identified as an incidental finding during neuroimaging procedures.
Purpose of the Study:
- To report the incidence of falx cerebri partial ossification.
- To discuss its differential diagnosis from other intracranial pathologies.
Main Methods:
- Retrospective review of 40 patients' brain CT and MRI scans.
- Analysis of incidental falx cerebri ossification findings.
Main Results:
- Falx cerebri partial ossification was an incidental finding in 40 patients.
- In most cases, diagnosis was uncomplicated.
- Distinguishing from calcified meningioma, hematoma, and meningeal infiltration was necessary in some cases.
Conclusions:
- Falx cerebri partial ossification is a common incidental finding on brain CT and MRI.
- Radiologists must be aware of potential differential diagnoses, including meningioma and meningeal disease.

01:22Sutures of the Skull
13.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

01:14Cranial Bones: Superior and Posterior View
7.6K
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,...
