title: Hemidiaphragmatic palsy following excision of cervical dumbbell neurofibroma in a patient with neurofibromatosis: Importance of assessing functional status of "non-limb" roots.
abstract: A 27-year-old male patient with neurofibromatosis type 1 who was operated on for a dumbbell neurofibroma of the cervical spine developed transient respiratory difficulty due to postoperative unilateral diaphragmatic palsy. This report emphasizes the need for preoperative assessment of residual function in involved non-limb roots, the role of intraoperative monitoring to take a decision on root sacrifice, and the need for optimizing respiratory function preoperatively, and describes a complication rarely reported in literature.
