Falcine Ossification: An Incidental Finding During Autopsy

Falx cerebri (FC) is made up of fibroblasts and large amounts of extracellular collagen, which are capable of undergoing osteogenic differentiation. Reports of ossification of the intracranial dural meninges are infrequent in medical literature. Ossification is a rarely detected incidental finding during imaging studies and mostly has no clinical implications. During the dissection of the cranium of a medico-legal autopsy case, a well-defined ossified segment measuring approximately 4.0 cm × 1.0 cm was observed in the anterior third of the FC. Isolated ossification of the cranial dura mater may occur with or without associated brain pathology.
