A 42-year-old female presented with left shoulder elevation weakness six months after a lymph node biopsy. A A clinical photograph shows left shoulder drooping and winged scapula. B High-resolution ultrasound (short-axis) at S2 shows rupture of the spinal accessory nerve (SAN) with traumatic neuroma (TN) on the affected side; the nerve lies superficial to the levator scapulae (LS). C Ultrasound of the trapezius (TM) on the affected side demonstrates denervation atrophy (thinning and increased echogenicity), with the underlying Rhomboids (RM) labeled for orientation.
