Presentation transcript:

A, In a patient with a right-sided scapula fracture and monoparesis following trauma, the right BPL (arrow) is thickened and asymmetrically enhancing at the truncus level between the anterior and middle interscalene muscles. A, In a patient with a right-sided scapula fracture and monoparesis following trauma, the right BPL (arrow) is thickened and asymmetrically enhancing at the truncus level between the anterior and middle interscalene muscles. There is no associated root avulsion or pseudomeningocele, suggesting only traction injury at first glance. B, However, the presence of an expansile spinal cord lesion at the C4-C5 level could signal the possibility of preganglionic injury. A. Aralasmak et al.
