Pathology of the neurohypophysis.
Neurohypophysis is composed of nerve fibers and has an intimate morphologic and functional contact with the hypothalamus. Pathology of the posterior lobe of the pituitary gland may develop several clinical features such as diabetes insipidus, which is caused by infections, vascular events, surgical complications and benign and malignant tumors as well as metastasis. Inappropriate secretion of vasopressin (Schwartzbartter syndrome) is due to excessive vasopressin release from the posterior pituitary or the ectopic production by various tumors, mainly carcinoid of the lung.
