Multiple mediastinal ganglioneuromas: report of a case.

A 23-year-old male known to have an asymptomatic mediastinal mass for four years was admitted due to progressive pitting edema of his arms and legs lasting for one week. The edema subsided prior to surgical extirpation of the left paraspinal mass. Initially recognized radiologically as a well-defined soft tissue mass with mottled calcification, on operation the mass was seen to be two well-encapsulated ganglioneuromas. Another small, round, nodular lesion abutted the contralateral side of the vertebral body on a computed tomographic scan of the chest. The postoperative course was unremarkable except for subsequently developed but well-tolerated regional anhidrosis involving the left side of the chest wall and the left upper limb.
