A Unique Case of an Aggressive Gangliocytic Paraganglioma of the Filum Terminale
Paragangliomas are rare neuroendocrine tumors that are mostly found in the head and neck. Even less common are gangliocytic variant paragangliomas of the spine for which there are only 7 other documented cases in the literature. We report a case of gangliocytic paraganglioma of the sacral spine in a 68‐year‐old man.
