No seguimento imagiológico, identificou-se um novo nódulo pulmonar em crescimento no lobo superior esquerdo. Após duas biópsias deste nódulo com material insuficiente, o paciente recusa a terceira tentativa. Este nódulo é intensamente hipermetabólico na PET-TC, sugestivo de metástase. A decisão em equipa multidisciplinar foi de tratamento com termoablação por micro-ondas do nódulo pulmonar. A termoablação guiada por imagem é uma técnica no campo da Radiologia de Intervenção, que tem surgido como opção minimamente invasiva para tratamento de tumores em múltiplos órgãos, com diversas indicações e ótimos resultados. Uma boa compreensão das características imagiológicas (in)esperadas após termoablação, também apresentadas neste artigo, é crucial para uma vigilância eficaz destes doentes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract We present a clinical case of a 71-year-old man with history of rectal adenocarcinoma cT3N1M0, previously treated with neoadjuvant chemotherapy/radiotherapy and anterior resection of the rectum. During imaging follow-up, a new growing pulmonary nodule was identified in the left upper lobe. After two biopsies of this nodule yielded insufficient material, the patient refused a third attempt. This nodule is intensely hypermetabolic on PET-CT, suggestive of metastasis. The decision by a multidisciplinary team was to treat the pulmonary nodule with microwave ablation. Image-guided thermal ablation is a technique in the field of Interventional Radiology that has emerged as a minimally invasive option for treating tumors in multiple organs, with various indications and excellent results. A good understanding of the (un)expected imaging characteristics after thermal ablation, also presented in this article, is crucial for effective patient surveillance and management.]]></p></abstract>
