Calcification of the Falx Cerebri: A Common and Benign Finding

Introduction

Calcification of the falx cerebri is a common finding on computed tomography (CT) scans of the brain. It is typically an incidental finding and is not associated with any symptoms or deficits. However, it is important to be aware of this finding in order to avoid misinterpreting it as a pathological process.

Definition

The falx cerebri is a sickle-shaped fold of dura mater that extends downward in the longitudinal cerebral fissure. It divides the cerebral hemispheres and provides structural support to the brain.

Causes

The cause of calcification of the falx cerebri is not fully understood. It is thought to be a result of the deposition of calcium salts in the dura mater. This process can occur as a result of normal aging, trauma, or inflammation.

Prevalence

Calcification of the falx cerebri is a common finding on CT scans of the brain. It is estimated to occur in up to 50% of the population. It is more common in elderly individuals and in those with a history of head trauma.

Clinical Significance

Calcification of the falx cerebri is typically an incidental finding and is not associated with any symptoms or deficits. However, it is important to be aware of this finding in order to avoid misinterpreting it as a pathological process such as a tumor or infection.

Conclusion

Calcification of the falx cerebri is a common and benign finding on CT scans of the brain. It is important to be aware of this finding in order to avoid misinterpreting it as a pathological process.
