"The falx cerebelli is attached posteriorly in the midline to the internal occipital crest of the occipital bone where it contains the occipital sinus 2. Its anterior edge exists freely between the partially separated cerebellar hemispheres in the posterior cerebellar notch. Superiorly it is attached to the tentorium cerebelli 1. Inferiorly, it extends to the posterior edge of the foramen magnum. At this point, it sometimes divides into two separate parts which extend anteriorly either side of the foramen magnum 2,3. Abnormalities of the falx cerebelli may be seen in normal individuals but are more common in the setting of brain or craniofacial abnormalities (particularly posterior fossa abnormalities) 5."
