Clinical Scorecard: A Case of Fully Thrombosed Middle Cerebral Artery Aneurysm Resembling Cavernous Malformation: A Detailed Case Study with Surgical Video and Literature Review

At a Glance

Key Highlights

• Complete thrombosis of MCA aneurysms is rare and often misdiagnosed as cavernous malformations.
• Initial imaging may show negative results for aneurysms, complicating diagnosis.
• Surgical intervention can involve ultrasonic removal of thrombus and plaque with clip reconstruction.
• Emphasize the importance of differential diagnosis to avoid mismanagement.

Guideline-Based Recommendations

Diagnosis

• Consider differential diagnosis of aneurysmal thrombosis when encountering lesions in typical vascular locations, even with negative angiography.
• Recommend pre-operative imaging techniques to enhance diagnostic accuracy.

Management

• Surgical intervention is indicated for definitive treatment of completely thrombosed aneurysms.

Monitoring & Follow-up

• Neuromonitoring during surgery is essential to ensure preservation of neurological function.

Risks

• Misdiagnosis can lead to inappropriate management and potential complications.

Patient & Prescribing Data

Adults presenting with severe headaches and atypical imaging findings.

Postoperative outcomes can be favorable with appropriate surgical intervention.

Clinical Best Practices

• Utilize high-resolution vessel wall MR imaging when available for better assessment of aneurysms.
• Evaluate CT and MRI features carefully to differentiate between aneurysms and other lesions.
• Involve multidisciplinary discussions for complex cases.
