Premature suture closure and ectopic cranial bone in mice expressing Msx2 transgenes in the developing skull.

The coordinate growth of the brain and skull is achieved through a series of interactions between the developing brain, the growing bones of the skull, and the fibrous joints, or sutures, that unite the bones. These interactions couple the expansion of the brain to the growth of the bony plates at the sutures. Craniosynostosis, the premature fusion of the bones of the skull, is a common birth defect (1 in 3000 live births) that disrupts coordinate growth and often results in profoundly abnormal skull shape. Individuals affected with Boston-type craniosynostosis, an autosomal dominant disorder, bear a mutated copy of MSX2, a homeobox gene thought to function in tissue interactions. Here we show that expression of the mouse counterpart of this mutant gene in the developing skulls of transgenic mice causes craniosynostosis and ectopic cranial bone. These mice provide a transgenic model of craniosynostosis as well as a point of entry into the molecular mechanisms that coordinate the growth of the brain and skull.

A Wormian Bone, Mimicking an Entry Gunshot Wound of the Skull, in an Anthropological Specimen

Wormian bones (WB) are irregular small cranial ossicles found along suture lines and fontanels. In Brazil, gunshot wounds to the skull are quite common in young individuals. Nevertheless, as far as we know, this is the first report of a WB giving an erroneous aspect of gunshot entrance due to its displacement position. The present manuscript describes the case of a Brazilian young man who died due to ballistic trauma, where a gaping bony defect on the right side of the skull was thought to be the exit wound of an injury related to the destruction found on the left side, highly suggestive of firearm injury. Thus, this case study has brought to light similarities between a traumatic lesion and an orifice of a WB, with emphasis on differential diagnosis during routine anthropological examinations.
