Gangliocytomas of the sellar region: A challenging diagnosis

Pituitary adenomas are the most common tumors growing in the sella and they account for up to 10-15% of intracranial neoplasms [20]. Other tumors may however be identified in the same region. Gangliocytomas are rare entities accounting for less than 2% of brain tumors [28,40]. They are well-differentiated slow-growing neuro-epithelial tumors formed by irregular groups of large multipolar neurons, often with dysplastic characteristics, arising from ganglion cells. They are WHO grade I tumors and a complete tumor resection is considered curative.
