Background: Metastases to the sellar region are extremely rare tumours in surgical series. The reported incidence has recently increased with advances in neuroimaging. Survival of patients with metastatic cancer has improved due to progress in oncologic therapies and diagnostics. Patients with sellar metastases (SM) follow a variable disease course that is not well defined.Objective: The objective was to evaluate the clinical characteristics, surgical ap...

Background: Posterior pituitary tumors (PPTs) present as clinically nonfunctioning space-occupying lesions of the sellar region. The diagnosis of PPTs is not possible on the basis of their clinical, radiological and biochemical features. Immunohistochemistry identifies them for their expression of TTF. They are virtually always mistakenly defined as one of the more common pituitary tumours. Due to their rarity, the long-term endocrine aspects and outcomes of PPTs are not well ...
