Images showing a lesion in an 18-year-old male patient with HAE recurrence before and after MWA treatment. A Enhanced CT was performed before the first ablation, and the lesion was marked by the red arrow. B CT scan on the first day after the first ablation, suggesting complete ablation. C At 17 months after MWA treatment, MRI-DWI suggested that the diffusion was limited around the lesions, suspected to be HAE recurrences. D CT scan on the first day after the second ablation suggesting complete ablation. HAE, hepatic alveolar echinococcosis; MWA, microwave ablation
