Traumatic Brain Injury in Patient with Biparietal Thinning.

Area of Science:

• Neurology
• Radiology
• Neurosurgery

Background:

• Intracerebral hemorrhage can result from head trauma.
• Biparietal thinning is a rare radiological finding characterized by symmetrical depressions and reduced diploe thickness in the parietal bones.

Observation:

• A 77-year-old male presented with altered consciousness after a fall.
• Head CT revealed a left parietal intracerebral hemorrhage and bilateral parietal fractures with midline crossing.
• Surgical intervention noted eggshell-like thinning of the fractured bone fragments.

Findings:

• The patient had biparietal thinning, an uncommon condition.
• Traumatic brain injury in patients with biparietal thinning is rarely documented.

Implications:

• Biparietal thinning may be an underrecognized predisposing factor for traumatic brain injury.
• Radiologists and clinicians should consider biparietal thinning when evaluating head trauma patients.
