Fig. 1c. Microcephalic Acrauius

This is a condition of acrania with the persistence of a diminutive and imperfectly developed brain. The brain tissue is represented by a soft, flabby mass of variable size which occupies the flattened base of the vaultless cranium. A meningeal-like membrane covers this structure in all cases. In some instances, fluid is present within this tumor-like mass, giving it the form of a cyst with walls of varying thickness. Such cases would more properly come within the subclassification of hydromicrocephalus. There were seven cases of microcephalic acrania in the series (12.3 per cent).
