Brief review
Neurogenic tumors of thorax may arise from the paraspinal ganglion of the symphathetic chain or from the intercostals nerves of the thoracic cage. Gnagiloneuroma is one of neurogenic tumor, composed entirely of ganglion cell and Schwannian stroma. Ganglioneuroma often manifests as an symptomatic mass and so, it is discovered on a routine radiographic study as this case. Plain radiograph typically shows a posterior mediastinal mass. On US, it is homogenous, hypoechoic mass with well defined borders. CT scan reveals low attenuation and homogenous mass on unenhanced CT and slight to moderate enhancement. At MR imaging, ganglioneuroma has low signal intensity on T1WI and high on T2WI. Enhancement of ganglioneuroma varies from mild to marked.
