- The metastatic tumor occurs in about 6% to 20% of all cases with central diabetes insipidus. Many kinds of cancers such as breast, lung, colon, prostate, leukemia, and lymphoma can metastasize to the pituitary and its stalk. Primary adenoid cystic carcinoma arising in the bronchus is an uncommon disease. It is histologically and ultrastructurally identical to salivary gland adenoid cystic tumor and is regarded as a slowly growing, low graded-malignancy. This is a case report of a 52-year-old woman with diabetes insipidus caused by a pituitary tumor that might have been associated with adenoid cystic carcinoma arising in the bronchus. The patient was diagnosed by water deprivation test, chest CT scan, bronchoscopic biopsy, and brain MRI scan. The water deprivation test showed the patient had central diabetes insipidus, while chest CT scan revealed a lung mass lesion with distal right intermediate bronchial obstruction. The primary malignancy was confirmed by bronchoscopic biopsy. Finally, we confirmed that the patient had a 7mm-sized mass in the posterior pituitary gland and a thickened stalk by brain MRI scan.

Abstract

- Dear Author, You have used abbreviations that will need to be defined in the main paper, i.e. PIT1, PROP1 and MRI. This is just for your advice. Pituitary agenesis is an uncommon cause of panhypopituitarism. It has been proposed that breech delivery, or birth trauma, is a major factor causing pituitary agenesis. Recent studies have suggested that genetic defects in the PIT1 or PROP1 gene might be involved in the pathogenesis of pituitary agenesis. In this case we report on the diagnosis of a 33-years old female patient with-growth retardation and sexual infantilism. We diagnosed anterior pituitary hormones deficiencies, with the exception of adrenocorticotropic hormone, by a combined pituitary stimulation test. We observed pituitary agenesis using sella MRI. Involvement of the PIT1 or PROP1 genes in this case remains to be determined. Here we report a case of pituitary agenesis found in an adult woman together with a brief review about this disease entity.
