What early finding detectable by MRI reflects the ongoing inflammation in an active Romanus lesion?
Answer
Edema in the adjacent bone marrow
Magnetic Resonance Imaging (MRI) possesses superior sensitivity compared to plain X-rays, allowing for the detection of early inflammatory processes before chronic structural changes are fully formed. For an active Romanus lesion, this early sign is the presence of edema, or fluid accumulation, within the bone marrow adjacent to the site of inflammation. This finding is specifically referred to as vertebral osteitis and is crucial because it signifies the active, underlying inflammatory cause before significant sclerosis has developed into the characteristic radiographic scar.
