Calcification of the Falx Cerebri: Physiological or Pathological?
What is Calcification of the Falx Cerebri?
Calcification of the falx cerebri is a common finding in computed tomography (CT) scans of the brain. The falx cerebri is a thin, sickle-shaped membrane that separates the two cerebral hemispheres. It contains blood vessels and nerves, and it houses the dural sinuses, which are large veins that drain blood from the brain. Calcification of the falx cerebri is the deposition of calcium salts within the falx. It is a common finding in older adults, and it is usually considered a physiological calcification, meaning that it is a normal part of the aging process. However, calcification of the falx cerebri can also be a sign of a pathological condition, such as: * Sturge-Weber syndrome * Tuberous sclerosis * Hypoparathyroidism * Pseudohypoparathyroidism These conditions can cause increased levels of calcium in the blood, which can lead to calcification of the falx cerebri and other tissues in the body.
Differential Diagnosis of Falx Cerebri Ossification
In most cases, there is no problem in the differential diagnosis of falx cerebri ossification during interpretation of CT scans. The calcification is typically symmetrical and located in the midline of the skull. However, there are some other conditions that can cause calcification of the falx cerebri, including: * Meningiomas * Gliomas * Metastatic tumors These conditions can be more difficult to differentiate from falx cerebri ossification, and further imaging studies may be necessary to make a diagnosis.
Treatment of Calcification of the Falx Cerebri
Treatment of calcification of the falx cerebri is not typically necessary. However, if the calcification is caused by a pathological condition, such as Sturge-Weber syndrome or tuberous sclerosis, treatment of the underlying condition may be necessary.
