We report two cases of lymphocytic infundibuloneurohypophysitis (LIH). A 32-year-old male and a 13-year-old male were admitted to our hospital because of a sudden occurrence of the diabetes insipidus (DI). MRI of both patients showed the disappearance of hyperintensity of the posterior pituitary in T1WI, pituitary stalk swelling and enlargement of the pituitary gland, with homogeneous enhancement by gadolinium. We thereby diagnosed LIH, so neither patient was operated on, but both were followed-up conservatively. We reviewed 51 cases of LIH. The patient's ages ranged from 4 to 74 years (mean 45.4 years). Based on the initial symptoms, DI was found in all cases. Almost all these cases revealed characteristic MRI findings similar to those in our cases. The mean follow-up period was 3.1 years. The rate of disappearance of radiological abnormalities was 56.2%, but only 13.7% of DI improved. If we encounter a patient presenting with idiopathic DI whose MRI is strongly suggestive of LIH, and barring the necessity of an urgent operation, careful conservative treatment is advised.

D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D010900 Pituitary Diseases Disorders involving either the ADENOHYPOPHYSIS or the NEUROHYPOPHYSIS. These diseases usually manifest as hypersecretion or hyposecretion of PITUITARY HORMONES. Neoplastic pituitary masses can also cause compression of the OPTIC CHIASM and other adjacent structures.

D010902 Pituitary Gland A small, unpaired gland situated in the SELLA TURCICA. It is connected to the HYPOTHALAMUS by a short stalk which is called the INFUNDIBULUM.

D020790 Diabetes Insipidus, Neurogenic A genetic or acquired polyuric disorder caused by a deficiency of VASOPRESSINS secreted by the NEUROHYPOPHYSIS. Clinical signs include the excretion of large volumes of dilute URINE; HYPERNATREMIA; THIRST; and polydipsia. Etiologies include HEAD TRAUMA; surgeries and diseases involving the HYPOTHALAMUS and the PITUITARY GLAND. This disorder may also be caused by mutations of genes such as ARVP encoding vasopressin and its corresponding neurophysin (NEUROPHYSINS).
