CT of intrathoracic neurogenic tumours.

Abstract

Fifteen patients with primary intrathoracic neurogenic tumours were evaluated using computed tomography (CT) scans. Schwannomas were demonstrated as homogeneous or slightly inhomogeneous densities on plain CT images; 4 of 5 schwannomas showed rim enhancement with some enhancement in the central portion of the tumour on post-enhancement CT images. Neurofibromas and ganglioneuromas were visualized as homogeneous densities on plain CT images. Three of 5 ganglioneuromas revealed homogeneous contrast enhancement of post-contrast CT images. A ganglioneuroblastoma and 2 neuroblastomas manifested slightly inhomogeneous tumour density on plain CT images. The inhomogeneity of the tumours was accentuated on contrast enhancement CT images.
