Scar tissue on MRI appears as hypointense on T1-weighted images and hyperintense on T2-weighted images due to collagen content and fluid accumulation. Scar tissue should be differentiated from keloids, hypertrophic scars, tumors, abscesses, and hematomas. MRI is a valuable diagnostic tool for characterizing scars and guiding treatment options such as surgical removal, laser therapy, radiation therapy, and corticosteroid injections. Complications may arise from post-surgical procedures and radiotherapy, highlighting the importance of careful evaluation and management.
