Studies have shown the benefits of endovascular treatment (EVT) in adult stroke cases, but its application in pediatric stroke remains controversial. Despite evidence of improved outcomes in adults, there are no established recommendations for EVT in children. Conducting individual case reports and case series is vital to understanding its potential advantages and disadvantages in this context. In this case report, a 9-year-old male initially diagnosed with gastroenteritis developed sudden left-sided weakness 1 day after admission. Comprehensive imaging revealed acute ischemia in the cerebellum, indicating a basilar artery thrombus. Urgent endovascular treatment (EVT) was performed 8.5 h after the onset of neurological symptoms, achieving successful revascularization. The patient underwent rehabilitation and was later discharged with improved neurological status. Despite extensive investigations, the stroke’s origin remained unknown. After six months, the patient exhibited complete neurological recovery, highlighting the patient’s remarkable resilience.
