A 72-year-old male was admitted to our hospital with a 2-year history of polyuria, prosopagnosia and aphasia. He showed characteristic clinical features of Pick's disease such as stereotyped verbal output and behavior and personality changes. CT and MRI scans showed marked atrophy in the bilateral anterior temporal lobes mild atrophy of the bilateral frontal lobes. SPECT scans revealed perfusion abnormalities in corresponding areas. A 6-hour-water deprivation test resulted in decrease in the urine volume and in concentration of the urine, suggesting abnormality of his secondary drinking behavior. Polyposia resulting in polyuria as a clinical manifestation may be due to stereotypic behavior which is often seen in Pick's disease.

A 69-year-old female was treated for hyperthyroidism and hypertension. In August 1984, she suddenly began suffering from polyuria and polydipsia. In October, she exhibited fever, headache, vertigo, and poor appetite, probably due to pituitary apoplexy. Her endocrine function was normal, except for partial diabetes insipidus. A contrast-enhanced CT brain scan revealed a pituitary adenoma with a ring-enhanced outer edge and a central low-density area. The MRI scan also indicated cystic adenoma. A CT scan examination repeated 6 months later showed an empty sella with a markedly decreased pituitary adenoma. This case report demonstrates that some empty sella are the final result of pituitary adenoma bleeding or infarction.

Three cases of symptomatic Rathkes' cleft cyst are described. Case 1. A 51-year-old man was admitted to the hospital for evaluation of intermittent headache, in April, 1985. He was neurologically free, but skull films disclosed a ballooning of the sella with thinning of the dorsum sellae. CT scan showed enlargement of the sella, but no abnormal density area in the sellar region. MRI revealed a round mass with high signal intensity located just posteriorly to the pituitary body. By a transsphenoidal approach, a thin-walled cyst was found at the posterior portion of the sella. Turbid mucinous fluid and the capsule of the cyst were subtotally removed. Histologic section of the specimen demonstrated that its wall was composed of a loose fibrous tissue lined by a single layer of ciliated cuboidal epithelium containing some goblet cells. Electron microscopy showed ciliated cuboidal cells, cells with microvilli, cells with light and large granules, and basal cells abutting on the basal lamina. Case 2. A 33-year-old female was referred to the hospital with complaints of severe headache and decreased visual acuity 0.02 in the left and 0.1 in the right, in July, 1985. Visual field examination revealed bitemporal hemianopsia. She had amenorrhea, galactorrhea and polyuria. CT scan and metrizamide CT cisternography detected a low density mass in the suprasellar region. Endocrinological studies disclosed hyperprolactinemia with partial hypopituitarism. She had a right frontal craniotomy and a suprasellar cyst was subtotally removed. Histologically, a cystic wall was lined by pseudostratified columnar epithelium supported by a loose fibrous tissue.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of pituitary adenoma associated with Rathke's cleft cyst is reported. A 35-year-old woman suffering from visual disturbance, polydipsia-polyuria and amenorrhea galactorrhea was admitted. Since 3 years before admission, she had been administered thyradin under the diagnosis of primary hypothyroidism. Visual acuity was 0.1 on the right and 0.06 on the left, and visual field examination showed bitemporal hemianopsia. Endocrinological study disclosed primary hypothyroidism and moderate hypopituitarism. CT scan showed a low density mass with ring-like enhancement extending in the enlarged sellar cavity and in the suprasellar region. MRI showed a cystic mass in the sellar cavity extending to the suprasellar region, and a solid mass in the left posterior part of the sellar cavity, and the later was thought to be pituitary adenoma. On August 27, 1984, right frontal craniotomy was performed. The right optic nerve was compressed upward, and the right carotid artery laterally with a grayish bulging mass. About 3 ml of grayish colloidal fluid was aspirated and the capsule of the cyst was excised. Postoperative course was uneventful. The visual acuity and visual field defects were improved. Endocrine examination revealed panhypopituitarism. Histologically, the cyst wall was composed of ciliated columnar cells and partially stratified squamous cells. The solid part showed typical pituitary adenoma. There are 5 reports in the literature on the combination of a pituitary adenoma and a Rathke's cleft cyst. In our case, it is thought that the long-standing hypothyroidism induced pituitary adenoma. Therefore, our case with combination of a pituitary adenoma and a Rathke's cleft cyst should be regarded as an occasional coexistence rather than the entity of the transitional cell tumor.

A 31-year-old man was admitted to our hospital because of a sudden onset of thirst, polyposia, and polyuria. Five years previously he had been admitted to our hospital because of a dry cough. On the first admission, the chest X-ray film had shown reticular shadows and bullous changes in both upper lung fields. Histological examination of a transbronchial lung biopsy specimen had revealed that the nodular lesion in the interstitium of the alveolar lesion consisted of an aggregate of many Langerhans cells with pale cytoplasm and partly convoluted nuclei. In addition, immunoperoxidase stain for S-100 protein had been strongly positive in numerous Langerhans cells in a bone biopsy specimen from a left mandibullar lesion, which is the same histological appearance as the lung lesion. A diagnosis of pulmonary eosinophilic granuloma had been made. The course after discharge was not progressive without treatment for 5 years, but the patient suddenly began to have thirst, polyposia, and polyuria. Dehydration, vasopressin tests, and the findings of MRI indicated diabetes insipidus due to a pathological change in the pituitary gland. Although diabetes insipidus is known to be a common complication of pulmonary eosinophilic granuloma, only 9 cases have been reported in Japan.

We are reporting on a case of diabetes insipidus (DI) and anterior pituitary failure revealing a breast cancer metastasis. Ten years after being diagnosed with a unilateral breast cancer, the patient presented with asthenia, thirst, polyuria and nocturia improved by subcutaneous DDAVP. MRI revealed a thickened pituitary stalk. DI is uncommon, late and usually asymptomatic in breast cancer. The association with an anterior pituitary failure is even more rare. In our patient the metastasis is in the pituitary stalk and seems to be due to meningeal deposits. MRI appears to be the best procedure to perform, showing a thickening stalk. Extension to the pituitary gland is related to direct tumor invasion from adjacent structures rather than haematogenous spread.

A 58-year-old woman was admitted to our hospital for impaired consciousness, hyperglycemia and bitemporal hemianopsia. She was diagnosed as having NIDDM one year ago and was treated with diet and glibenclamide (1.25 mg/day) for 6 months. However, she stopped her medical treatment one month ago and then polydipsia and general fatigue were manifested. She was admitted to a hospital five days ago at which time hyperglycemia (405 mg/dl) and anemia (Hb8.0g/dl) were detected. She was transferred to our hospital for control of blood glucose and further examination of bitemporal hemianopsia. She showed typical acromegalic features including enlargement of the nose, lips and tongue, increased heel pad and acral growth. Conscious disturbance was cured by the infusion of saline and the administration of insulin. Endoscopy revealed an active gastric ulcer (A1). Endocrine data disclosed increased GH levels in plasma and urine, whereas plasma IGF-1 levels were low. Plasma GH paradoxically increased following the administration of TRH. A water deprivation test showed an impaired increase in urinary osmolarity, indicating partial central diabetes insipidus (DI). MRI with Gd-contrast revealed a macroadenoma which progressed toward suprasella. She was diagnosed as having acromegaly, partial DI and probable hyperosmolar hyperglycemic nonketotic diabetic pre-coma. Polyuria (5-101/day) due to partial DI was controlled by the administration of DDAVP (10 micrograms/day). The constant subcutaneous administration of octreotide (240 micrograms/day) resulted in normal plasma GH levels and a marked shrinkage of the pituitary tumor. The pituitary tumor was finally removed by the transsphenoidal approach following treatment with octreotide for 4 months. HE staining of the pituitary tumor showed atrophic and acidophilic cells surrounded by hyaloid connective tissue. After the surgery, plasma GH levels were normalized and complications were cured. In conclusion, this is a very rare case of acromegaly associated with diabetic pre-coma and partial DI, and effectively treated with constant subcutaneous infusion of octreotide.

A 55 year old woman with multifocal eosinophilic granuloma (MEG) is described. She developed facial numbness and twitching followed by slowly progressive cerebellar symptoms. Two years later polyuria and polydipsia were noted. A CT of the brain showed multifocal enhancing lesions, and MRI showed areas of hyperintensity on T2 weighted studies in the cerebellar peduncles, pons, and midbrain. Radiographs of the skull, pelvis, and long bones were normal, but a 99mTc diphosphonate bone scan and MRI showed bone lesions compatible with granuloma. The diagnosis of MEG was made by bone biopsy. This is believed to be the first case of MEG with such unusual clinical profiles and radiographical findings. Skeletal surveys are indicated for patients with unexplained focal or multifocal inflammatory changes in the cerebellum.

A case of sinus thrombosis occurring during combination chemotherapy with CDDP and VP-16 (PE) for a suprasellar germ-cell tumor is presented. A 5-year-old girl developed polyuria, polydipsia and headache in April, 1991 and became unconscious on May 10, 1991, when MRI and CT demonstrated a suprasellar tumor and marked hydrocephalus. After a ventriculo-peritoneal shunt operation, radiotherapy and two courses of PE therapy were carried out. During the second course of PE therapy, diabetes insipidus became quite difficult to control and severe hypovolemic hypernatremia developed. While it was being treated, the patient developed a clonic convulsion of her left extremities and visual disturbance. CT scan demonstrated a right parietal hemorrhagic infarction and IV-DSA suggested thrombosis of the superior sagittal sinus. Laboratory data disclosed DIC. The main cause of sinus thrombosis in this patient was considered severe dehydration. It is also possible that cisplatin and steroid played a role. In addition to these, dysfunction of hypothalamus, which is one of the regulatory centers of the plasma concentration of factor VIII, may have contributed to the acceleration of blood coagulation. This case re-emphasized the importance of preventing dehydration and monitoring the blood coagulation fibrinolytic system during PE therapy in patients with a suprasellar germ-cell tumor accompanied with diabetes insipidus.
