Patient with FIGO stage IIB squamous cell carcinoma of the cervix. (a) Initial pretreatment MRI (axial T2-weighted image) demonstrates primary cervical tumour with parametrial invasion (long arrow) and left pelvic node involvement (short arrow). No para-aortic lymphadenopathy was demonstrated on abdominal sequences. Fused FDG-PET/CT confirmed highly FDG-avid primary tumour and a single pelvic nodal metastasis (b). Therefore the patient was not suitable for radical surgery and underwent primary chemoradiotherapy treatment. FDG-PET/CT was performed 3 months after completion of treatment (c,d). This demonstrates complete response to the irradiated tumour in the pelvis (c). However, there is disease relapse above the radiotherapy field in the para-aortic region (arrow, d). This finding indicates an adverse prognosis.
