A 54-year-old woman presented with a 3-month-history of blurred vision and refractory
headache. Examination revealed severe bilateral visual acuity compromise, normal
campimetry and bilateral papilledema. As a mean to investigate raised intracranial
pressure, neuroimaging studies were performed and showed extensive sellar mass (Figure). Patient underwent transsphenoidal approach
for resection of pituitary mass which disclosed metastasis of neuroendocrine lung tumor.
Chest CT showed a mass in the anterior segment of right lower lobe of lung. Although
symptomatic pituitary gland tumors are common in clinical practice11 . Rennert J, Doerfler A. Imaging of sellar and parasellar lesions.
