Summary
This paper reports a rare case of a ruptured pericallosal artery aneurysm with a mirror-image counterpart. Surgical treatment was successful, offering insights into cerebral aneurysm pathogenesis.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cerebrovascular Diseases
Background:
- Pericallosal artery aneurysms are uncommon cerebrovascular lesions.
- Ruptured aneurysms pose a significant risk of subarachnoid hemorrhage and poor neurological outcomes.
- Bilateral or mirror-image aneurysms present unique diagnostic and therapeutic challenges.
Observation:
- A 47-year-old woman presented with a ruptured pericallosal artery aneurysm.
- A second aneurysm was identified in a mirror position on the contralateral side.
- Angiography excluded common anatomical variants like azygos anterior cerebral artery.
Findings:
- Successful surgical management of the ruptured pericallosal artery aneurysm was achieved.
- The patient experienced no post-operative complications.
- The case highlights the possibility of associated, mirror-image aneurysms.
Implications:
- This case contributes to the understanding of rare cerebral aneurysm presentations.
- It underscores the importance of thorough vascular imaging in suspected aneurysm cases.
- The successful surgical outcome provides a potential treatment paradigm for similar rare conditions.
