Blood-brain barrier disruption due to cerebral arteriography: CT findings

Area of Science:

• Neurology
• Radiology
• Neuroimaging

Background:

• Cerebral arteriography is an imaging technique used to visualize cerebral arteries.
• Blood-brain barrier (BBB) disruption can occur secondary to various medical procedures.
• Understanding BBB changes is crucial for diagnosing and managing neurological conditions.

Observation:

• Computed tomography (CT) was utilized to assess two patients with suspected blood-brain barrier (BBB) disruption.
• The disruption was linked to prior cerebral arteriography procedures.
• Specific patterns of contrast enhancement were observed in the brain imaging.

Findings:

• The first patient exhibited diffuse contrast enhancement in the right frontotemporal region, corresponding to the middle cerebral artery's territory.
• The second patient displayed patchy contrast enhancement affecting both gray and white matter across both cerebral hemispheres.
• These distinct imaging findings suggest varied responses or mechanisms of BBB disruption.

Implications:

• The study highlights the potential for cerebral arteriography to induce blood-brain barrier disruption.
• CT imaging can effectively demonstrate the extent and pattern of BBB changes post-procedure.
• Further investigation into the mechanisms underlying BBB disruption following arteriography is warranted to improve patient safety and outcomes.
