Muscular atrophy and weakness in the lower extremities in Behçet’s disease: A case report and review of literature

Figure 1 Enhanced T1-weighted image of both thigh muscles. A: Coronal section shows enhancement of the right rectus femoris muscle (arrow); B: Transverse section shows heterogeneous enhancement of the vastus lateralis (arrow) and adductor magnus (arrow head) muscles.

Figure 2 Muscle biopsy of the right vastus lateralis muscle. A: Light microscopy shows atrophic myofiber (white arrow) and compensatory hypertrophy (orange arrow). Increased endomysial connective tissue is also seen (hematoxylin and eosin, 200 ×); B: Electron microscopy shows atrophic small myofiber with redundant basal lamina.
