ABSTRACT

Penile cancers compose less than 1% of ali urogenital cancers. Spinal nerve invasion was not reported in the literatüre before. İn this case report,our aim was to present the 18F- FDG PET/ CT images of a patient who had surgery due to penile cancer. Spinal nerve invasion was detected in the PET/CT images and this is correlated with MRI. A 57-year-old patient, after two years he had radical penectomy surgery, had an abdominopelvic CT scan in terms of control. Following the detection of a soft tissue lesion in the right obturator region during abdominopelvic CT imaging, this patient was directed to our clinic for PET/CT scanning.ln the PET/CT images, in the right obturator region, high pathologic 18F- FDG uptake was observed in a soft tissue lesion which was considered as metastasis. İn addition, at the right S-2 foramen level, a gradually increased FDG uptake was observed. İn the MRI scan which was performed for correlation, in the right S2 nerve root, asymmetric contrast uptake was seen. Spinal nerve invasion is difficult to detect .As PET/CT has the advantage to scan whole body, perform anatomical and functional imaging at the same time, it detected the spinal nerve invasion.This finding was also verified with MRI.
