CTICasesPosterior Mediastinal Ganglioneuroma
Imaging findings
CT in a 30-year-old female with breast cancer shows a smoothly lobulated, sausage-like posterior mediastinal mass that extends vertically along five vertebral bodies. MRI would show classic low T1 and high T2 signal with delayed enhancement.
Key takeaways
Ganglioneuromas are benign neurogenic tumors of the autonomic nervous system. Unlike schwannomas or neurofibromas which are more spherical, ganglioneuromas characteristically grow vertically along multiple vertebral bodies in the posterior mediastinum of young adults.
