Calcification of the Falx Cerebri

Embryology and Etiology

The falx cerebri, a fibrous membrane that separates the two cerebral hemispheres, originates from embryonic mesenchymal cells. During development, friction hemorrhage or other factors may induce ossification within the falx.

Physiological Calcification

As individuals age, physiological calcifications may accumulate within the falx cerebri. These calcifications are often incidental findings on non-contrast computed tomography (NCCT) scans.

Structure and Clinical Significance

The falx cerebri contains numerous blood vessels and nerves. It serves as a common site for falcine meningiomas, benign tumors that can arise from the lining of the brain.

Prevalence and Age-Related Changes

Calcification of the falx cerebri is more prevalent in older individuals. This is attributed to the accumulation of calcium deposits over time.

Diagnostic Considerations

Calcification of the falx cerebri is typically detected through neuroimaging. Radiologists can identify these calcifications on conventional radiographs, CT scans, and MRI studies. In most cases, these calcifications are incidental findings that do not require specific medical intervention.
