title: [Case report of surgically treated dumbbell-type schwannoma arising in the right brachial plexus with von Recklinghausen disease].
abstract: We encountered a patient with dumbbell-type schwannoma arising in the right brachial plexus with von Recklinghausen disease. The patient was a 9-year-old girl. An abnormal shadow was detected high in the thoracic cavity by thoracic radiography. Thoracic CT and MRI demonstrated at the apex of the thoracic cavity a tumor measuring 9.0 x 6.0 cm, which was diagnosed as a dumbbell-type neurogenic tumor derived from the brachial plexus. Most cases of such tumors growing inside and outside the spinal cavity have reportedly been treated in a single surgical procedure. However, since the tumor in this patient was large, the intrathoracic portion was removed first in order to minimize the magnitude of the surgical invasion. The residual intraspinal tumor was removed during subsequent surgery. No neurological problems were observed after surgery. Patients with dumbbell-type schwannomas arising in the right brachial plexus appear to be very rare, and this patient was considered noteworthy.
