Incidental findings of symmetrical well-corticated bony defects in the posterior aspect of bilateral parietal bones near the sagittal and lambdoid sutures suggest enlarged parietal foramina.
Case Discussion
Enlarged parietal foramina are due to ossification defects of the parietal bones, which are normally ossified by the fifth month of gestation. They may be inherited in an autosomal dominant manner with high but incomplete penetrance.1,2
Most cases are asymptomatic and found incidentally on imaging for other causes. However they may occasionally become symptomatic or may be associated with other pathologies.
