Calcification of the Falx Cerebri: A Physiological Finding

Introduction

Calcification of the falx cerebri is a common finding in computed tomography (CT) scans and is generally considered a physiological calcification, particularly in adults. However, in children, punctate intracranial calcifications (PICs) in the falx cerebri and tentorium cerebelli are rare and may indicate underlying pathology.

Prevalence and Characterization

In adults, calcification of the falx cerebri is typically observed in the posterior aspect and is often bilateral. It occurs as a result of aging-related changes in the dura mater and is not associated with any specific disease process.

In contrast, PICs in the falx cerebri and tentorium cerebelli in children are uncommon and require further investigation. These calcifications may be associated with genetic disorders, metabolic disturbances, or certain infections.

Clinical Significance

While calcification of the falx cerebri is generally a benign finding in adults, it can be an important diagnostic clue in children. The presence of PICs in these structures may warrant further evaluation to determine the underlying cause and guide appropriate management.

Conclusion

Calcification of the falx cerebri is a common finding in CT scans and is often a normal variant in adults. However, in children, PICs in the falx cerebri and tentorium cerebelli are rare and may signal an underlying pathological condition. Therefore, it is essential for clinicians to be aware of this distinction and to consider further evaluation when appropriate to ensure timely diagnosis and appropriate care.
