Myxoid Solitary Fibrous Tumor: CT Discovery, MRI Characterization, and the Radiologic Clues That Matter
Edited by ScholarGen MediAI Team Executive Clinical Summary A small superficial soft-tissue nodule may appear insignificant on an initial CT examination, particularly when it is discovered incidentally during imaging performed for an unrelated clinical complaint. Yet size alone does not determine the diagnostic importance of a soft-tissue mass. This case illustrates that principle clearly. A woman in her 40s underwent CT angiography of the chest, abdomen, and pelvis during evaluation of chest pain. The examination incidentally demonstrated a superficial soft-tissue nodule in the right buttock measuring approximately 2.1 × 1.6 cm. The lesion was not described as a typical fatty mass and was located within the superficial subcutaneous tissues. Approximately three years later, MRI demonstrated enlargement to approximately 3–4 cm. The lesion was slightly hypointense to skeletal muscle on T1-weighted imaging and markedly hyperintense on T2-weighted sequences. Thin internal low-signal ...
