Progressive bilateral thinning of the parietal bones
Skeletal Radiology
|January 1, 1982
Summary
Parietal thinning, a progressive condition affecting older adults, was identified in 2.37% of patients. This finding suggests it is a disease, not a congenital variation.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Parietal thinning is a poorly understood condition.
- Its nature as an anatomical variant or disease is debated.
Observation:
- A 14-year observation of progressive bilateral parietal thinning prompted a study.
- Skull films of 3,636 patients were analyzed.
Findings:
- Parietal thinning occurred in 2.37% of patients (86/3,636).
- It was more prevalent in women (sex ratio 1:1.9).
- Mean age of onset was 72 for females and 63 for males.
- Progression was observed in 10 of 25 patients with prior films.
Implications:
- Parietal thinning is a slowly progressive disease in middle-aged and elderly individuals.
- It is not an anatomical variant or congenital dysplasia of the diploe.
- Further research into the etiology and management of parietal thinning is warranted.
