Abstract

Falx cerebelli is a sickle shaped Dural folds that usually harbors a single occipital venous sinuous at its posterior attachments. A study of falxcerebelli in 40 cadavers was done in Department of Anatomy Sivaraj Institute of Medical Sciences. In 4 specimens, accessory falx cerebelli was observed. The length and thickness of falx cerebelli was measured and compared with normal falx cerebelli and its sinuses were observed. Variation in the falx cerebelli showing marginal sinus, accessory sinus draining in to sigmoid sinus were observed. Neurosurgeons and Neuroradiologist should be aware of such variations as these could be potential source of haemorrhage or may lead to erroneous interpretation during imaging of the posterior cranial fossa.
