Sellar collision tumor involving metastatic lung cancer and pituitary adenoma: radiologic-pathologic correlation and review of the literature.
Collision tumors of the sella turcica involving metastases to pituitary adenomas are rare. We report a case of a collision tumor involving metastatic lung cancer with an emphasis on the neuroimaging and histopathological studies. A review of the literature including the diagnostic and management implications as well as pathogenetic mechanisms is also discussed.
