Occipital Lobe Petalia Measurements on Brain CT Scans

Abdulwahab F. Alahmari


Petalia or occipital bending is an anatomical asymmetry where one occipital lobe protrudes behind the other occipital lobe and makes an impression on the inner table of the skull.

Purpose: The aim of this paper is to measure brain petalias and check the relationship between petalia with age, gender, other measurements in the brain, handedness, location of the petalia, degree of the petalia angle, etc.

Methods: A retrospective study of  33 patients’ CT scans were studied and analyzed.

Results: The research shows that there is no relation whatsoever between them. As well, this paper will provide descriptive analyses like; frequency, mean, and standard deviation.

Conclusions: This paper finds new findings about levels of petalia, classification, and handedness/hemisphere dominance association. The results show no relation between age and gender from one side and petalia’s dimensions on the other side.
