Tumor metastasis to the hypophyseal system has rarely been reported with either clinical or radiographic evidence. A 52-year-old woman presented with polydipsia, polyuria, and loss of appetite. She was diagnosed as having diabetes insipidus caused by pituitary micrometatasis of lung adenocarcinoma. After she had been treated with radiation therapy to the pituitary gland, the gland size was reduced as confirmed by magnetic resonance imaging, and her urine volume decreased. However, meningitis carcinomatosa appeared later. This was a rare case of secondary diabetes insipidus due to pituitary metastasis of lung cancer.

A 59-year-old woman whose first clinical manifestations were polyuria and polydipsia was admitted to our hospital. Brain MRI showed multiple mass lesions and a thickened pituitary stalk. Chest CT showed hilar and mediastinal lymphadenopathy and a small nodule measuring about 1.5 cm in the apex of the right lung. Histopathological examination revealed adenocarcinoma of the lung, and primary lung cancer with diabetes insipidus secondary to pituitary stalk metastasis was diagnosed. She received systemic chemotherapy and whole-brain irradiation concurrent with intranasal desmopressin (DDAVP) treatment. Although the size of the tumor was reduced, her symptoms did not improve and the same dose of hormone replacement therapy was required. We present this rare case and review the twenty cases of metastatic pituitary lesions arising from lung cancer reported in the literature.

A 53-year-old man admitted for thirst, polyposia, and polyuria. Large cell lung cancer T3N2M1 (Stage IV), and central diabetes insipidus caused by pituitary metastasis of lung cancer, were diagnosed. We gave him desmopressin acetate, and chemotherapy with paclitaxel and carboplatin. But pituitary metastasis increased and invaded the hypothalamus. After irradiation of the pituitary and hypothalamus, metastatic focus diminished and desmopressin acetate was tapered.

A 71-year-old man was admitted with high fever, thirst, polyposia and polyuria. After examination, lung cancer (adenocarcinoma T1NOM1, Stage IV) and central diabitus insipidus caused by pituitary metastasis of lung cancer, were diagnosed. We gave him desmopressin acetate, gamma knife surgery for pituitary metastasis and chemotherapy with paclitaxel and carboplatin, and his symptoms improved. However, his lung cancer progressed. Diabitus insipidus caused by lung cancer is rare.

A 54-year-old woman had been given a diagnosis with scleroderma and interstitial pneumonia due to scleroderma when she was 45 years old. Thirst, with resulting polydipsia and polyuria (about 7 liters/day) were present since May, 2004, and bloody sputum appeared in June of 2004. The patient was admitted to our hospital. Chest CT examination showed multiple nodules in the bilateral lower lung field and multiple movable subcutaneous nodules on the abdomen. Small-cell lung cancer (metastases in the pituitary, subcutaneous tissue, and lungs) was diagnosed by transbronchial lung biopsy and subcutaneous nodule biopsy of the abdomen. The final diagnosis was diabetes insipidus and Cushing syndrome. Chemotherapy was done with CDDP and VP-16, which resulted in reduction of the tumor and improvement in endocrinological findings. Nevertheless, chemotherapy could not be continued because of infected bullae. The patient died of deteriorating illness after 91 sickness days. We concluded that this case was Cushing syndrome caused by ectopic adrenocorticotropic hormone-producing small cell lung cancer, and that it presented with diabetes insipidus because of pituitary metastasis. Therefore, when drastic endocrinological changes are found, it is important to examine for cancer, including lung cancer, as soon as possible.

Tumor metastasis to the pituitary gland has been infrequently reported, and this is probably because only a small proportion of these patients are symptomatic. Most of the symptoms of this malady are related to diabetes insipidus. A 78-year-old man was diagnosed 2 years previously with stage IIIA adenocarcinoma of the lung and treated with sequential chemoradiation therapy and later with whole-brain radiation therapy because of newly developed brain metastasis; he was then admitted to our hospital with symptoms of polydipsia and polyuria. He was confirmed to have central diabetes insipidus that was caused by the pituitary metastasis from lung cancer. His symptoms resolved after treatment with desmopressin. Because of the rarity of this manifestation in lung cancer patients, we report on this case along with a brief review of the relevant literature.

The pituitary gland and infundibulum can be involved in a variety of medical conditions, including infiltrative diseases, fungal infections, tuberculosis, primary and metastatic tumors. Metastases to the pituitary gland are absolutely rare, and they are generally secondary to pulmonary carcinoma in men and breast carcinoma in women. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The posterior lobe involvement may explain why patients with pituitary metastases frequently present with diabetes insipidus. We are presenting a case report of a 48-year-old male patient with sudden onset of polyuria and persistent thirst. Laboratory results revealed central diabetes insipidus. Computed tomography (CT) scan of the brain showed a mass located in the sella turcica and suprasellar region. CT scan of the chest showed a mass in the right superior lobe with mediastinal lymphadenopathy. Bronchoscopy and biopsy demonstrated a pulmonary adenocarcinoma. Thus, we made a diagnosis of lung cancer with local and pituitary metastases. The patient received radiotherapy on the pituitary gland and adjuvant chemotherapy. As a result the intrasellar and suprasellar mass decreased in size and urinary output accordingly decreased. In conclusion, in patients presenting with sudden onset of diabetes insipidus pituitary metastases should be taken in account in differential diagnosis.

Metastases in the sellar region are rare and are frequently found incidentally or in necropsies. Only 7% are reported to be symptomatic. Diabetes insipidus, anterior pituitary dysfunction, visual field defects, headache/pain and ophthalmoplegia are the most commonly reported symptoms. We present the cases of two male patients with a small-cell lung carcinoma whose first clinical symptoms were due to pituitary metastasis. One case presented with symptoms of cavernous sinus invasion and panhypopituitarism and the other case with diabetes insipidus. Both patients had a rapid progression of their disease despite chemotherapy and died after a few months. Pituitary metastases occur most commonly with breast cancer in women and lung cancer in men. The presence of polyuria and polydipsia in an oncologic patient should alert the physician for diabetes insipidus and, if confirmed, an imaging procedure of the pituitary gland is mandatory. Treatment for these tumors is often multimodal and includes surgery, radiation therapy, chemotherapy and hormone replacement. Although surgical series have not shown any significant survival benefits given by tumor resection, the patient's quality of life may be improved.

Pituitary apoplexy is a rare but potentially life-threatening condition caused by the sudden enlargement of a pituitary adenoma secondary to infarction and hemorrhage. Surgical stress is 1 cause of pituitary apoplexy, but asymptomatic pituitary adenomas are difficult to diagnose preoperatively. Here we report a case of a 78-year-old male who had postoperative pituitary apoplexy after surgery for lung cancer. He underwent right upper and middle lobectomy and lymph node dissection for squamous cell carcinoma with obstructive pneumonia. On the sixth postoperative day he developed sudden-onset fever, respiratory distress, and polyuria. Brain magnetic resonance imaging revealed an enlarged, hemorrhagic pituitary gland. He was treated with steroid hormone replacement. Subsequent endocrine hormone stress tests revealed recovery of his pituitary function. Based on his clinical course, the patient was diagnosed with acute adrenal insufficiency and diabetes insipidus due to pituitary apoplexy.

Cushing's syndrome due to young small-cell lung cancer (SCLC) is recognized as being extremely rare. We herein present the case of a 35-year-old nonsmoking man who presented with thirst and polyuria. Laboratory examinations showed hyperglycemia, hypokalemia and liver enzyme elevation. Imaging examinations revealed the presence of multiple liver tumors and lymph node swelling. The levels of serum neuroendocrine tumor markers were elevated. The patient was diagnosed with SCLC based on the pathological examination of a biopsy specimen from the right supraclavicular lymph node. The physical findings, including proximal myopathy, truncal obesity and pigmentation suggested high levels of glucocorticoids. An immunohistochemical examination of the tumor showed that it was positive for adrenocorticotropin (ACTH). An endocrinological investigation allowed for the definitive diagnosis of SCLC with ectopic ACTH production.
