Challenging Management of a Rare Complex Cerebral Arteriovenous Malformation in the Corpus Callosum and Post-Central Gyrus: A Case Study of a 41-Year-Old Female.

Cerebral arteriovenous malformations (AVMs) are rare but complex vascular anomalies, particularly challenging when located in eloquent regions such as the corpus callosum and post-central gyrus. This report aims to highlight the management and outcomes of a 41-year-old female patient with a hemorrhagic AVM in these critical areas, emphasizing the importance of early surgical intervention and advanced imaging techniques. The patient presented with a right-sided tonic-clonic seizure and expressive aphasia, prompting imaging that revealed a complex AVM with deep venous drainage and arterial supply from the anterior cerebral artery. A multidisciplinary team performed microsurgical resection via a left parasagittal fronto-parietal craniotomy. The surgical approach prioritized hematoma evacuation followed by a stepwise dissection of the AVM nidus under intraoperative monitoring. Complete resection of the AVM was confirmed through postoperative angiographic and CT imaging. The patient showed stable recovery over 15 months, with no recurrence or new neurological deficits. This case demonstrates the critical role of advanced imaging, intraoperative strategies, and a multidisciplinary approach in achieving successful outcomes. Microsurgical resection remains the gold standard for AVMs in eloquent and deep-seated brain regions. Early diagnosis and tailored surgical interventions are crucial for managing these high-risk cases. This case underscores the importance of integrating advanced imaging, strategic surgical planning, and intraoperative monitoring to minimize complications and optimize long-term recovery.
