? 2022 Elsevier Inc.Cerebral arteriovenous malformations (AVMs) are dynamic neurovascular disorders that occur mainly in young adults, presenting an annual risk of rupture of 2% ? 4% per year.1 They can be asymptomatic, representing an incidental radiologic finding, or present with neurologic deficits according to their brain location, size, and presence or absence of bleeding.2,3 AVMs located in eloquent areas4 represent a great challenge for neurosurgeons, sometimes directed to alternatives therapies (e.g., embolization, radiotherapy) due to the difficulty in planning and surgical technique. Despite the complexity, we consider that there is benefit to removing these lesions; this can be done safely, as with the adequate microsurgical strategy and neuroanatomic knowledge. In Video 1, we show the case of a 55-year-old male patient with an AVM positioned over the right central sulcus. He presented with intermittent left-hand paresthesia followed by an episode of involuntary movements in the left arm without loss of consciousness and with spontaneous resolution. Angiography showed an AVM feed by branches of the middle cerebral artery and multiple venous drainage for the Trolard complex and superficial middle cerebral vein, with a 4-cm nidus, making it grade III in the Spetzler-Martin classification.4 The patient underwent surgery with total resection of the lesion without any complication or new neurologic deficits.
