Existence of Enlarged Parietal Foramina in Bone Collections.

Introduction: The enlarged parietal foramen (EPF) is a defect in the ossification of the parietal bone that is well described in the literature using a variety of nomenclatures. Individuals with EPF can present symptoms such as migraines, vomiting and intense pain when light pressure is applied to the skull. However, it can go unnoticed for a lifetime. Materials and Methods: At the Human Bone Collection department of the Universidade Federal de Pernambuco, 2 craniums (CAV 90, 96 years old and CAV 16, 81 years old) and were identified as having EPF, both from females. Results: There was no apparent kinship between both craniums. The sagittal length, the coronal width, the sagittal suture distance, the coronal suture distance and the lambdoid suture distance of each enlarged parietal foramen were evaluated, with the following results: sagittal length: 5.5 cm (CAV 90), and 5.0 cm (CAV 16); coronal width: 3.1 cm (CAV 90),and 3.4 cm (CAV 16); sagittal suture distance: 2.9 cm (CAV 90), and 2.3 cm (CAV 16); coronal suture distance: 1.8 cm (CAV 90), and 4.6 cm (CAV 16); and lambdoid suture distance: 5.0 cm (CAV 90), and 3.0 cm (CAV 16). The parietal foramen of both craniums exhibited equivalent measurements. Conclusion: Due to the low incidence of EPF, the identification of the 2 craniums with this condition in a collection of 105 skeletons makes the discovery relevant. In reference to craniums exhibiting EPF, this is an important tool for study and forensic research, since its appearance is linked to heredity.
