Gangliocytic paraganglioma in cauda equina region, with biochemical and neuropathological studies. Case report.
Biochemical analysis of a nonfunctional paraganglioma in the cauda equina region demonstrates that its catecholamine content is predominantly dopamine with small amounts of noradrenaline and adrenaline. Scattered mature large neurons characterize the tumor as gangliocytic paraganglioma. Ultrastructural study shows intracytoplasmic neurosecretory granules in the neoplastic cells.
