Wilms’ tumor also called as nephroblastoma is commonly seen extracranial solid tumor involving kidneys in children. Rarely, Wilms’ tumor can arise from ectopic nephrogenic remnants located outside the kidneys. Extrarenal Wilms’ tumor comprises 3% of total Wilms’ tumor with its incidence even less common in adults. We report the staging and restaging fluorodeoxyglucose positron emission tomography-computed tomography findings in a case of locally advanced metastatic extrarenal adult Wilms’ tumor involving the retroperitoneum.
“Hot” patella sign is a less commonly seen finding in bone scintigraphy defined as increased tracer activity in the patella greater than the ipsilateral distal femur and ipsilateral proximal tibia. We present a case of suprapatellar knee bursitis manifesting as unilateral “hot” patella sign on three-phase

Tc-methylene diphosphonate bone scintigraphy. This case portrays the image findings of suprapatellar bursitis on three-phase bone scintigraphy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
