COMO AVALIAR LESÕES ÓSSEAS INCIDENTAIS NA TC E RM - PARTE 1

How to Evaluate Incidental Bone Lesions in Imaging — Part 1 Incidental bone lesions are very frequent findings in routine radiology, especially in CT and MRI scans performed for other reasons. But the big question is: how to distinguish a probably benign lesion from a lesion that deserves investigation or referral? In this first part of the lesson, I explain the general concepts for evaluating incidental bone lesions, focusing on the radiologist's practical reasoning. We will talk about: ✅ How to begin the analysis of an incidental bone lesion ✅ How to interpret the relationship of the lesion with the bone cortex ✅ Difference between endosteal slicing, cortical remodeling, and cortical rupture ✅ Why these concepts completely change the degree of suspicion of the lesion One of the most important points of the lesson is understanding that not every alteration of the cortex means aggressiveness. Endosteal slicing may indicate internal growth of the lesion over the cortex, but it needs to be interpreted along with depth, extent, and context. Cortical remodeling suggests slow bone adaptation, often associated with lesions that grow more indolently. Cortical rupture, on the other hand, is a finding of greater concern, especially when associated with soft tissue mass, aggressive periosteal reaction, or other signs of tumor behavior. How to avoid the trap of loss of cortical definition on CT with intact cortex on MRI. This lesson is aimed at radiologists, residents, and physicians who want to gain more confidence in evaluating incidental bone lesions on CT and MRI. 📌 Also watch Part 2, where we continue with the practical reasoning and application of criteria in the evaluation of bone lesions. #Radiology #MusculoskeletalRadiology #BoneLesions #BoneTumors #BoneRADS #SSRBoneRADS #CTscan #MagneticResonanceImaging #Musculoskeletal #Radiologist #MusculoskeletalImaging
