Craniotabes (kra-ne-o-ta' -biz) [upaviov, skull ; tabere, 

 to waste away]. An atrophy of the cranial bones oc- 

 curring in infancy, with the formation of small, shal- 

 low, conical pits in the bone-substance. These pits 

 are granular within, and present a worm-eaten ap- 

 pearance around the margin. They are most usually 

 found in the posterior inferior region of the parietal 

 bone, but may be seen in any of the other cranial 

 bones. They form from within outward, so that in 

 life often they cannot be found. Craniotabes is proba- 

 bly a result of rhachitis, syphilis, or marasmus. The 

 craniotabetic pits are in some way associated with the 

 rapid growth and development of the brain ; they may 

 be due to a premature formation of the markings of 

 the convolutions on the skull. They are only encoun- 

 tered during the first months of life, that is, up to the 

 sixteenth month. This disease is not a serious one as 

 regards danger to life.
