CTICasesChest Wall Desmoid Tumor
Imaging findings
Chest CT and MRI show a speculatively margined, infiltrative soft-tissue mass in the posterior chest wall, involving the trapezius and paraspinal muscles. The mass demonstrates high signal intensity on T2-weighted and STIR MRI sequences, and intense enhancement after gadolinium administration.
Key takeaways
Desmoid tumors (deep fibromatosis) are histologically benign but locally aggressive soft-tissue tumors that arise from fascial or musculoaponeurotic structures. In the chest wall, they present as infiltrative masses that speculate into adjacent muscles, leading to high rates of local recurrence after surgical resection due to microscopic infiltration beyond the gross margins.
