dc.description.abstract | Paragangliomas are neuroendocrine tumors of paraganglionic tissue which are extremely rare in the sellar area. We present a case of sellar paraganglioma with parasellar and suprasellar extension in a 70-year-old man who presented with headache. CT demonstrated sellar mass with suprasellar and right parasellar extension. The lesion was removed subtotally via a trans-sphenoidal approach. Histopathological diagnosis was paraganglioma. Differential diagnosis between paragangliomas and unusual types of pituitary adenomas, especially null-cell adenomas, is made by presence of cell nests (Zellballen) in paraganglioma, lack of immunopositivity for pituitary hormones, cytoplasmic immunopositivity for chromogranin A and neuron-specific enolase, and immunonegativity for cytokeratin 19, cytokeratin 20 and endomysial antibody. In the case of a mass in the sellar region, paraganglioma, although rare, should be included in the differential diagnosis. | en_US |
