Abstract

<p>A man in his fifties was being monitored for the challenge of addressing an unruptured cerebral arteriovenous malformation. Nevertheless, the patient began to experience gait disturbances and cognitive decline. Eventually, the patient was referred to our medical center for further examination and treatment. Magnetic resonance imaging (MRI) of the head revealed high T2WI signals in the bilateral basal ganglia, indicating potential edema in the basal ganglia resulting from impaired venous return caused by cerebral arteriovenous malformation. Given the patient’s symptomatic status, therapeutic intervention was recommended, but the option of craniotomy was not advisable. Therefore, a combination of endovascular therapy and stereotactic radiotherapy was considered an appropriate treatment regimen. After the treatment, the cerebral arteriovenous malformations were no longer visible on imaging scans, and the T2WI hyperintensities in the bilateral basal ganglia showed improvement. Despite these positive outcomes, the patient continued to experience extrapyramidal symptoms such as limping. It is crucial to exercise caution when treating unruptured cerebral arteriovenous malformations, as irreversible neurological symptoms may develop over time, which should be taken into consideration.</p>
