Ganglioneuroma (occasionally called a "ganglioma") is a rare and benign tumor of the autonomic nerve fibers arising from neural crest sympathogonia (undifferentiated cells of the sympathetic nervous system). [1] However, ganglioneuromas themselves are fully differentiated neuronal tumors that do not contain immature elements. [2]

The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.

A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen). When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma.
Neuroblastoma is one of the peripheral neuroblastic tumors (pNTs) that have similar origins and show a wide pattern of differentiation ranging from benign ganglioneuroma to stroma-rich ganglioneuroblastoma with neuroblastic cells intermixed or in nodules, to highly malignant neuroblastoma.
On MRI, it usually shows hyper or iso-intensity on T1-weighted images and heterogenous hyperintensities on T2 weighted images. Pleural schwannoma typically shows fatty degeneration, hemorrhage, perivascular hyalinization, and cystic formation thus giving heterogenous hyperintensities on T2 weighted images.
