İntramusküler Miksoma

Miksoma, mezenkimal hücrelerden köken alan benign bir tümördür. İskelet kasından köken aldığında, intramusküler miksoma olarak adlandırılır. En sık olarak alt ekstremitedeki büyük kaslarda yerleşir. Genellikle 40- 60 yaş arasında ve kadınlarda daha sık görülürler. Bu lezyonlar ağrısız şişlik şeklinde prezente olurlar. Tanısı ile ayırıcı tanısında, MRG oldukça önemlidir. T1-ağırlıklı görüntülerde "peritumoral fat rind" olarak adlandırılan bulgu, miksoma yönünden yüksek tanısal değere sahiptir. Bu yazıda, uylukta şişlik şikayetiyle gelen ve intramusküler miksoma saptanan 50 yaşındaki kadın hasta, radyolojik bulguları ve ayırıcı tanıları vurgulanarak, anlatılacaktır.

Intramuscular Myxoma

Myxoma is a benign tumor arising from mesenchymal cells. When originate from skeletal muscle is called intramuscular myxoma. Most often it settles in the large muscles of the lower extremities. It usually occurs between 40 and 60 years of age and more often in women. These lesions present as a painless swelling. MR imaging is very important in the diagnosis and the differential diagnosis. On T1-weighted images, the findings called 'peritumoral fat rind' has a high diagnostic value for the myxoma. In this article, 50-year-old female patient will be explained who has swelling in the thigh and intramuscular myxoma determined, with emphasis on radiological findings and differential diagnosis.
