INTRODUCTIONImage-guided thermal ablation, preferably with ultrasonography (US), is increasingly used for treatment of small liver tumours. Perfluorobutane-contrast-enhanced US (pCEUS) is a promising tool that may allow for targeting of tumours that are otherwise imperceptible on greyscale US. Although pCEUS has been reported to be effective, the literature has been limited outside of Japan and South Korea. We aimed to provide data that supports the use of pCEUS in the thermal ablation of sonographically occult liver tumours.METHODSWe conducted a retrospective single-centre study of 35 consecutive patients who underwent pCEUS-guided ablation of 48 liver tumours with a median size of 1.2 cm. Periprocedural, one-month post-treatment and relevant follow-up imaging studies were reviewed. Electronic records were also obtained, with long-term follow-up data of 12–28 months being available for 32 patients.RESULTS36 (75%) tumours that were imperceptible on greyscale US became visible with pCEUS. Overall, complete tumour ablation at one month was 89%. 1 (3%) patient developed a major complication following treatment, while 6 (17%) had minor post-treatment complaints. The local tumour progression rate was 17%, with a median time of 14 months.CONCLUSIONpCEUS has a role in US-guided thermal ablation of liver tumours, offering a high technical success rate that is comparable to reported data. Additional benefits may include improved procedural time and freedom from ionising radiation. 相似文献

Odontoameloblastoma is a rare odontogenic tumour, characterised by simultaneous occurrence of an ameloblastoma and a compound or complex odontoma in the same tumoral mass. The tumour is seen in first three decades and affects mandible or maxilla equally, commonly found posterior to the canines. The management is similar to unicystic ameloblastoma and odontoma excision. A long term follow up is a must to observe the recurrence. Here we present a rare case of odontoameloblastoma in a 17 year old male, presenting as an asymptomatic anterior mandibular swelling with chief complaint of missing lower front teeth. 相似文献
