Thinning of parietal bone bilaterally is extremely rare but well known phenomenon. Approximate prevalence is 0.4-0.5% according to radiological scans, case reports and anthropologic researches. Even though biparietal osteodystrophy occurs mostly in over 60-year-old women, it shows no special association with race or geographical area tendency. Current definition was changed by understanding that is a pathological situation, not an anatomical variety or result of growing old in time. Biparietal osteodystrophy may have an unusual presentation and treatment still remains unclear. We aim to present a patient with biparietal osteodystrophy associated with minor head trauma that caused parietal fracture and epidural hematoma underneath.
