Objective: The aim of this study was to assess the role of positron emission tomography/computed tomography (PET/CT) scan in preoperative staging of testicular tumors and therefore determining the line of appropriate management.Patients and methods: During two year duration we prospectively evaluated 34 patients with testicular tumors diagnosed by histopathology after biopsy or orchidectomy. All patients underwent PET/CT examinations following a preset protocol that included low dose non contrast study, whole body scanning post 18F-FDG injection and post IV contrast CT scan. The images obtained were reconstructed using dedicated software and workstations. Results of PET/CT examinations were compared with histopathology and serum markers.Results: Out of 34 cases all masses were malignant (germ cell tumors). 20 masses (58.8%) were diagnosed by histopathology as seminoma subtype while 14 masses (41.2%) were diagnosed as non seminomatous germ cell tumors (NSGCT) subtype.There were 16 true positives, 14 true negatives, 2 false positive, and 2 false negative cases. Sensitivity, specificity, positive predictive value and negative predictive values were 88.9%, 87.5%, 88.9% and 87.5% respectively.Conclusion: Positron emission tomography/computed tomography (PET/CT) has a major role in preoperative staging of testicular tumors and defines the need of post operative adjuvant therapy

Do we need 18F-FDG PET/CT scan in staging and management of testicular tumors?
