Abstract
Skeletal muscle is an extremely uncommon site for metastases. We report a 47 year old male patient with a previous history of left radical nephrectomy due to renal cell carcinoma. Initial PET/CT scan in in March 2008 showed a slightly hypermetabolic focus in the right infraspinatus muscle consistent with solitary intramuscular metastasis. A repeat PET/CT scan in July 2009 revealed metabolic progression of right intraspinatus metastasis as well as other foci in right rectus abdominis, piriformis and left vastus medialis muscles. PET/CT is useful for the detection of intramuscular metastases of renal cell carcinoma. Increased focal FDG uptake in muscle groups should be carefully evaluated when reading PET scans

Abstract
Kas içi metastazlar son derece nadir görülen bir durumdur.Olgumuz 47 yaşında bir erkek hasta olup, böbrek hücreli karsinom nedeniyle daha önce sol nefrektomi uygulanmıştır. Mart 2008 tarihinde yapılan ilk PET/BT çalışması, sağ infraspinatus kası içerisinde hafi fçe hipermetabolik bir odak göstermiş olup, görünüm soliter kas içi metastaz ile uyumlu olarak değerlendirilmiştir. Temmuz 2009 tarihinde yapılan takip PET/BT’de ise, önceki çalışmada sağ infraspinatusda izlenen kas içi metastazda metabolik progresyon ve sağ rektus abdominis, piriformis ve sol vastus medialis kas gruplarında yeni gelişen metastazları göstermiştir. PET/BT, böbrek hücreli karsinomda görülebilen kas içi metastazların saptanmasında etkin bir yöntemdir. PET görüntüleri değerlendirilirken, kas grupları içerisindeki artmış FDG tutulum odakları dikkatle değerlendirilmelidir
