A case of an invasive schwannoma developing at gibbus due to an old tuberculous spine

Abstract

The invasive schwannoma in the spine is a rare clinical entity. There have been no reports of schwannoma arising from tuberculous spine. The authors report on a case in which invasive cystic schwannoma arose at old tuberculous spine and paraplesia progressed by the tumor. The tumor excision and resection of the sequestra achieved satisfying neurological improvement. Although development of cystic tumor in the tuberculous spine may be extremely rare, it should be considered in the differential diagnosis, especially when systemic symptoms of tuberculosis were absent.
