Positron emission tomography (PET)/computed tomography (CT) with 18 F fluorodeoxyglucose (18 F-FDG) has become pervasive as a tool for staging, restaging and follow-up of testicular cancer patients, especially in characterization of equivocal lesions on ultrasound (US), CT and MRI (Els et al., 2010). Testicular cancer represents between 1% and 1.5% of male cancers and 5% of urologic tumors, with 3 to 10 new cases occurring per 100,000 males per year (Albers et al., 2012). High risk factors include young age, prior family history, HIV, undescended testes, carcinoma In-situ and being white man. Over the last 30 years, the incidence of testicular cancer has increased (Manecksha et al., 2009). Bilateral presentation is low i.e.1% to 2% at diagnosis. There is a clear predominance (90%-95%) of germ cell tumors (GCT) despite of overall variation in presentation. Testicular cancers are classified
