Detailed analysis of elastofibroma dorsi cases detected incidentally on thorax CT

Abstract

Aim: Elastofibroma dorsi (ED) is a benign pseudotumor detected by CT and/or MRI due to the penetration of fibrous and fatty tissues between the muscle structures and is more common in elderly people, especially in women, with subscapular topography. This study investigated the prevalence of elastofibroma dorsi in large series and CT findings. Material and Methods: A total of 469 patients (212 women, 257 men) who underwent thoracic CT for various reasons were included in this study. The presence, dimensions, contour and density of ED were investigated in these patients. Results: The mean age of 469 patients was 54.51±17.42 (18-88 years). Elastofibroma was detected in 15.4% (n=72) of these patients. It was determined that 69.9% (n=51) of the patients with ED were female, and the mean age of these patients was 63.21±15.72. ED was usually isodense in both sexes. Again, in both sexes, ED was more regularly contoured, and the fat planes between adjacent muscle structures were usually closed. Conclusion: Additional studies are not required when the lesion is typical and asymptomatic on CT scans. However, surgical treatment may be recommended if the lesion is symptomatic or if doubt remains regarding the benign nature of the lesion.

Elastofibroma dorsi’de BT bulguları: tek merkezli bir çalışmad

Abstract

Amaç: Elastofibroma dorsi (ED), fibröz ve yağlı dokuların kas yapıları arasına girmesi sonucu BT ve/veya MRG ile tespit edilebilen, sıklıkla subskapular topografi ile yaşlı kişilerde, özellikle kadınlarda daha fazla görülen iyi huylu bir psödotümördür. Bu araştırma, Elastofibroma Dorsi’nin geniş serilerde görülme prevelansı ile BT bulgularını araştırmak amacı ile yapılmıştır. Materyal ve Metod: Bu araştırmaya çeşitli sebepler ile toraks BT çekilen, 469 hasta (212 kadın, 257 erkek) dahil edildi. Bu hastalarda ED varlığı, boyutları, konturu ve dansitesi araştırıldı. Bulgular: 469 hastanın yaş ortalaması 54.51±17,42 (18-88 yaş) idi. Bu hastaların %15,4 (n=72)’de Elastofibroma tespit edildi. ED tespit edilen hastaların %69,9 (n=51)’nun kadın olduğu ve bu hastaların yaş ortalamasının 63,21±15,72 olduğu belirlendi. ED her iki cinsiyette genellikle izodens idi. Yine her iki cinsiyette ED daha çok düzenli konturlu idi ve komşu kas yapıları ile arasındaki yağ planları genellikle kapalı idi. Sonuç: BT ile yapılan taramalarda lezyon tipik ve asemptomatik olduğunda ilave çalışmalara gerek yoktur. Bununla birlikte, lezyon semptomatikse veya lezyonun iyi huylu doğasına ilişkin şüphe devam ediyorsa cerrahi tedavi önerilebilir.
