Transclavicular approach for a large dumbbell tumor in the cervicothoracic junction.

Abstract

Neurogenic dumbbell tumors occur more frequently in the cervical than in the thoracic or lumbar spine. Cervical paravertebral masses usually do not become exceptionally large because they are superficial and are palpated easily. Thoracic tumors can become large before they are detected. The authors describe a large intrathoracic dumbbell tumor arising from the C8 nerve root. The intraspinal tumor was resected through a posterior approach. In the second stage, dividing the clavicle, the intrathoracic component was resected by separating it from the lung. Two years after treatment, the preoperative neurologic deficit had improved except for weakness of muscles innervated by the C8 nerve root. Radiographs showed no residual or recurrent mass at the apex of the lung. Sometimes a retroclavicular location may conceal a large paravertebral mass, such as Pancoast tumors. As described here, the transclavicular approach gave adequate access to the cervicothoracic junction.
