Imaging findings
Frontal chest radiograph shows a subtle abnormal mediastinal lung interface projecting over the expected location of the aortic arch/knob. CT reveals an extra-pleural, oval-shaped mass in the paraspinal region. Lack of significant enhancement was noted.
Key takeaways
Ganglioneuromas are benign nerve sheath cell tumors, typically arising from the sympathetic chain in the paraspinal location. While schwannomas are more common, ganglioneuromas are an important part of the differential diagnosis for paraspinal masses, especially when they lack significant enhancement.
