Familial incidence of foramina parietalia permagna.
The author presents three cases of congenital parietal bone defects in two generations of one family. Two of them present paired, symmetrically located perforations of the parietal bones and case No. 3 presents a single, 6 X 7 cm defect of the parietal bones, located in the midline. In the presented cases the diagnosis was confirmed by skull radiograph, however, in case 1 angiography was also performed. These congenital skull defects are considered, so far, of no clinical significance, and no associated abnormalities among affected individuals have been found. The problems involved with the formation and assessment of treatment of these defects are discussed.
