Anatomy of the head and neck
Published in Helen Whitwell, Christopher Milroy, Daniel du Plessis, Forensic Neuropathology, 2021
The falx cerebri is located within the longitudinal fissure separating the left and right cerebral hemispheres. Inferiorly, it is attached to the crista galli and the internal occipital crest of the inner surface of the occipital bone. Both the superior and inferior sagittal venous sinuses lie within the falx cerebri. Its posterior margin is continuous with the tentorium cerebelli, which separates the cerebellar hemispheres from the cerebrum, but is at right angles to the falx cerebri. The transverse sinus is located within the tentorium cerebelli. Finally, the falx cerebelli separates the two cerebellar hemispheres in the midline but inferior to the tentorium cerebelli (Figure 1.3).

The falx cerebelli is a small, sickle-shaped infolding of dura below the tentorium, partially separating the cerebellar hemispheres. It extends forwards from the internal occipital crest to the posterior cerebellar notch.

The falx cerebelli is a vertical dural fold that lies inferior to the cerebellar tentorium between the two lobes of the cerebellum, projecting into the posterior cerebellar notch in the posterior cranial fossa. Its base is directed upwards and attached to the posterior part of the inferior surface of the tentorium cerebelli in the midline. Its posterior margin is attached to the internal occipital crest and contains the occipital sinus.1,2

The midline of the posterior fossa was marked by drawing a straight line, from the midpoint of the clivus to the internal occipital protuberance and its continuation as the internal occipital crest. It was termed line 2. T2 weighted sequential axial images were taken for measurements. Further confirmation was done with constructive interference in steady state (CISS) sequence images when available.
