ganglioneuroma

 [gang″gle-o-nu-ro´mah]
a benign neoplasm composed of nerve fibers and mature ganglion cells; called also gangliocytoma, ganglioglioneuroma, and ganglioma.

gan·glio·neu·ro·ma

(gang'glē-ō-nū-rō'mă),
A benign neoplasm composed of mature ganglionic neurons, in varying numbers, scattered singly or in clumps within a relatively abundant and dense stroma of neurofibrils and collagenous fibers; usually found in the posterior mediastinum and retroperitoneum, sometimes in relation to the adrenal glands.

ganglioneuroma

a rare benign neoplasm composed of nerve fibers and ganglion and Schwann cells. Generally, these occur in dogs, intracranially in the brain or cranial nerve ganglia, or rarely in the adrenal medulla or autonomic ganglia. See also neuroblastoma.

At noncontract CT, a ganglioneuroma is of low attenuation and homogeneous and demonstrates mild to moderate homogenous or even heterogeneous enhancement (Figure 19).
If the mass contains mainly neuroblasts (immature ganglion cells), it is referred to as neuroblastoma; however, when the mass is composed entirely of mature ganglion cells and other mature tissue, it is considered a ganglioneuroma, while ganglioneuroblastomas have both immature and mature cells (JOSHI, 2000).

The treatment of the ganglioneuroma is total surgical excision and histology provides a confirmatory diagnosis.
These tumours differ only in their progressive degree of cellular and extracellular maturity, with ganglioneuroma being the most mature hence well differentiated and neuroblastoma being the least (2).
The definitive diagnosis of the tumor being a ganglioneuroma was established after permanent sections of the tumor were analyzed.

Between April 2001 and October 2004, we examined 18 tumor, 70 BM, 5 PB, and 4 PBSC samples, taken at diagnosis or during treatment, from 1 patient with ganglioneuroblastoma (GNB),1 patient with ganglioneuroma (GN), and 28 patients with NB.
A ganglioneuroma is an uncommon tumor of the sympathetic nervous system.

These tumours have a broadspectrum of behaviour from spontaneous regression to maturation to a benign ganglioneuroma or aggressive disease with metastatic dissemination leading to death.
