Abstract
A 54-year-old man of bladder and prostate cancers complained of painful left thigh swelling and fever. Although the clinical presentation and imaging studies suggested infectious process, biopsy confirmed metastatic bladder cancer. F-18 FDG PET/CT scan demonstrated additional hypermetabolic focus at left psoas muscle. Skeletal muscle metastasis is rare and remains a diagnostic challenge, particularly in the absence of widespread metastasis. However, it should be included in the differential diagnosis for oncologic patients presenting with muscular pain refractory to antibiotics. It also highlighted the value of F-18 FDG PET/CT scan to detect occult metastatic foci and to monitor treatment response.
