calcification is observed in 65% of patients and this calcification is not found in early childhood (3).

The larger lesion is found in the anterior falx

Factors that could contribute to an anterior susceptibility to strain forces in humans include the relatively large mass of the human frontal lobes and the fact that the anterior human brain is less constrained in its movement inside the skull than is the posterior brain, which is embraced by the falx
and the tentorium.
From Latin Falx
(= sickle) referring to the shape of the paramere.
Origen incierto; talvez esta palabra esta relacionada con falx
, falcis, hoz, en cuyo caso, etimologicamente, falco, -onis signifique "el de dedos o pies torcidos", a semejanza de las aves de rapina.
Our subsequent studies of unembalmed cadavers went on to reveal fascia [tissues] hanging from the free border of the falx
cerebri [the projection, of the dura mater--the fibrous membrane forming the outermost covering of the brain and spinal cord--separating the hemispheres of the cerebrum--the largest portion of the brain].
2] Shearing also can occur at areas of restricted movement in the brain, including the falx
and the parasagittal and fronto-orbitotemporal surfaces, causing cortical contusions.
In lateral position, the right hemisphere drops through the gravity and the left is hanged by the middle sagittal falx
Multiple discrete, well defined, varying sizes of rounded and semilunar shaped with broad dural based hyperdense solid masses with homogenous intense contrast enhancement lying over the right cerebellar hemispheric convexity and along the posterior border of petrous bones bilaterally as well as in the interhemispheric fissure attaching falx
