Charcot-Bouchard Aneurysm Diagnosed with CTA and MRA

Area of Science:

• Neurology
• Vascular Neurology
• Neuroradiology

Background:

• Charcot-Bouchard aneurysms are rare, small, distal micro-aneurysms affecting perforating lenticulostriate arteries.
• Basal ganglia hemorrhage is a serious neurological event, often associated with hypertension, but can have other causes.

Observation:

• This report details a rare case of basal ganglia hemorrhage.
• The hemorrhage was attributed to a ruptured Charcot-Bouchard aneurysm.
• Advanced imaging techniques, including Computed Tomography Angiography (CTA) and Magnetic Resonance Angiography (MRA), were crucial in demonstrating the aneurysm.

Findings:

• The diagnosis was confirmed by selective catheter angiography.
• The study emphasizes the diagnostic value of CTA and MRA in visualizing these micro-aneurysms.
• Contrast-enhanced CT is recommended for young patients with basal ganglia hemorrhage, particularly when arterial hypertension is absent or subarachnoid hemorrhage is present.

Implications:

• This case underscores the importance of considering rare etiologies for basal ganglia hemorrhage.
• Accurate diagnosis through advanced angiography is vital for appropriate patient management.
• Early identification of Charcot-Bouchard aneurysms can guide treatment strategies and improve patient outcomes.
