若年者の早期における離断性骨軟骨炎と上腕骨頭壊死の鑑別を要した1例

Key Points

• To differentiate between osteochondritis dissecans and early avascular necrosis in a young patient.
• Case report of an 18-year-old male athlete presenting with right shoulder pain.
• Utilization of MRI for imaging, including T1-weighted and STIR sequences, and CT scans for bone assessment.
• Functional blood flow evaluation using Gadobutrol-enhanced MRI.
• MRI indicated distinct low-signal regions with slight bone sclerosis observed on CT scans.
• Blood flow assessment confirmed no significant obstruction, leaning towards osteochondritis dissecans as the diagnosis.
• Treatment led to improvement in MRI findings after six months, suggesting effective management.
