Abstract
Patellar metastasis is an exceptionally rare manifestation of skeletal metastasis, attributed to the patella's limited red marrowcontent and sparse vascularity. Patellar metastases have been most frequently reported in lung and renal carcinomas,whereas patellar involvement from prostate adenocarcinoma is exceedingly uncommon. Recognition of such unusual sitesis important, as delayed diagnosis may result in pain, restricted mobility, and pathologic fracture. This case adds to thelimited literature on patellar metastasis from prostate adenocarcinoma and highlights the value of whole-body Ga-68 PSMAPET/CT in detecting rare sites of skeletal metastasis that may influence staging, prognosis, and clinical management.Keywords: prostate adenocarcinoma, patellar metastasis, Gallium-68 PSMA PET/CT.
TL;DRThis case adds to the limited literature on patellar metastasis from prostate adenocarcinoma and highlights the value of whole-body Ga-68 PSMAPET/CT in detecting rare sites of skeletal metastasis that may influence staging, prognosis, and clinical management. (Semantic Scholar)
