In October, 2015 around 10 cm in length tumour of irregular form invading parapharyngeal, submandibular, palatoglossal arch, soft palate and palatopharyngeus was seen on the MRI scan of head and neck (Figure 1).

Ablation was performed under ultrasound, CT and fusion CT/MRI guidance (Figures 2-4).

As there was local tumour progression detected seven weeks later on the control MRI scan of the head and neck, the resection of exophytic compound of the tumour was performed and cryoablation of tumours in soft head and neck tissues was repeated two weeks later (Figure 5).
