1 Radiation-Induced Myonecrosis Presenting as a Subcutaneous Mass After Combined Modality Therapy for Non-small Cell Lung Cancer  Vamsidhar Velcheti, MD, Eve Gilstrap, RN, Jeffrey Bradley, MD, Ramaswamy Govindan, MD  Journal of Thoracic Oncology  Volume 2, Issue 9, Pages (September 2007) DOI: /JTO.0b013e31811f3a91 Copyright © 2007 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 The dose to the isocenter within the target volume was 7350 cGy. Journal of Thoracic Oncology 2007 2, DOI: ( /JTO.0b013e31811f3a91) Copyright © 2007 International Association for the Study of Lung Cancer Terms and Conditions

3 FIGURE 2 A computed tomographic scan of the chest revealed an ill-defined low-attenuation lesion within the left trapezius muscle lying medial to the left scapula at the level of the fifth and sixth ribs without invasion of the underlying ribs or the adjacent scapula grossly.

4 FIGURE 3 A computed tomographic-guided biopsy of the soft tissue mass revealed only benign-appearing epithelial cells with scattered elongated nucleoli, probably representing fibroblasts. There were no features diagnostic for malignancy. A follow-up evaluation 4 months later showed spontaneous resolution of the mass.
