RESUMEN
We present the staging fluorodeoxyglucose (FDG) positron emission tomography (PET-CT) findings in a patient with a functional urinary bladder paraganglioma. The PET-CT scan showed markedly increased FDG uptake into bilateral pelvic nodes that was consistent with regional nodal involvement. These findings were confirmed on histopathology. At present, there are no reports of PET-CT findings in urinary bladder paragangliomas.

We present the FDG PET-CT findings in a patient with persistent pain 7 weeks after a nephrectomy and lymph node dissection for a sarcomatoid renal cell carcinoma. Although conventional imaging was unable to detect evidence of metastatic spread outside the para-aortic nodes, a PET-CT scan showed unexpected extensive dissemination. Currently, there are no reports in the literature of the PET-CT findings in sarcomatoid renal cell carcinomas.

Solid and cystic papillary epithelial neoplasms (SCPEN) of the pancreas are rare tumours seen in young women. Pancreatic masses in children are extremely rare and SCPEN should be considered in the radiological differential diagnosis. Although there have been many series of SCPEN reported in the published literature in adults, only two series have focused on paediatric patients. The radiological and histopathological features of SCPEN in a paediatric patient are presented.
