A 76-year-old man was admitted because of general fatigue and lumbago. Two years before admission, hyponatremia and hyperkalemia were pointed out, subsequently hydrocortisone (20 mg/day) was given under the diagnosis of panhypopituitarism. The marked improvement was found in the electrolytes abnormality. On examination at admission, there was no abnormality of anterior pituitary function. In addition to the extremely low level of plasma renin activity and aldosterone concentration, the persistent microhematuria and hyperuricemia were found, however, renal histology only showed the benign arteriosclerosis but no significant alteration in juxtaglomerular apparatus and glomeruli. The urinary prostacyclin metabolite output was rather increased compared to that of normal subject, suggesting that prostaglandins may not be responsible for the defect of renin secretion. Although, the cause was still unknown, small dose of dexamethasone was extremely effective to resolve electrolytes abnormality and hematuria.

The typical patient with post-traumatic hypopituitarism is a young adult male presenting months to years after an automobile accident, following which he was unconscious for several days. He will probably have sustained a fracture of the base of the skull and on recovery is likely to have permanent visual or other neurological sequelae. Temporary or permanent diabetes insipidus may have occurred. The features of panhypopituitarism such as weight loss, fatigue, faintness, loss of libido, and impotence may have been ascribed to depression or the "postconcussion syndrome" and often inappropriate treatment and rehabilitation advised. The striking feature on review of the literature is that the pathological consequences of head injury to the pituitary and hypothalamus have been well described, while only 47 cases of traumatic hypopituitarism have been reported. The most likely reason for this disparity is that head injury of sufficient severity to cause hypothalamic and pituitary damage commonly led to death. More patients now survive, owing to the availability of intensive care; accordingly, most cases have been reported in the last 15 years. However, several patients are described in whom the initiating head injury was not associated with a skull fracture or followed by coma. We recommend that patients with major head injury (defined by post-traumatic amnesia greater than 24 hours), and in particular those with fractures of the base of the skull or diabetes insipidus should be closely monitored for symptoms and signs of endocrine dysfunction and appropriate dynamic pituitary-function tests performed.

A fifty-year-old woman was admitted to our hospital because of generalized edema, progressive symptoms of fatigue and weakness of ten years' duration. After an uneventful third delivery, 24 years before admission, she could not lactate and developed oligomenorrhea and then amenorrhea. Laboratory evaluation revealed panhypopituitarism and pituitary cell antibodies were positive. Both CT scans and MR images showed empty sella. This case is postpartum hypopituitarism without a preceding history of excessive bleeding and may be autoimmune hypophysitis.

A 41-year-old man was admitted to our hospital because of general fatigue, sexual debility and finger stiffness. Endocrinological examinations revealed that he had panhypopituitarism, resulting in secondary adrenal insufficiency, hypothyroidism and gonadal failure. Computed tomography (CT) of the head demonstrated a low density intrasellar mass, while brain magnetic resonance imaging (MRI) showed a high intensity mass extending from the intrasellar to suprasellar region in both T1WI and T2WI. The mass was removed by transsphenoidal surgery and histologically diagnosed as Rathke's cleft cyst. Replacement with hydrocortisone and levothyroxine sodium greatly improved the clinical symptoms. Rathke's cleft cyst causing panhypopituitarism is relatively rare. The clinical and endocrinological characteristics of Rathke's cleft cyst were discussed based on the findings in 49 Japanese cases including this case and two other cases we have experienced.

A 38-year-old male with panhypopituitarism due to Rathke's cleft cyst associated with a pituitary oncocytoma is reported. The presenting signs were general myalgia and slight fatigue. Endocrine examinations revealed panhypopituitarism. Magnetic resonance imaging disclosed a suprasellar cystic lesion of the pituitary gland. Cytological examination demonstrated ciliated cells in the mucinous fluid flowing from the cyst during the pituitary operation. A pituitary oncocytoma with randomly scattered S-100 immunoreactive cells was found upon histologic examination of the nodular tissue curettaged from the internal wall of the cyst. These results suggest that the pituitary adenoma was derived from folliculostellate cells included in the Rathke's cleft wall.

A 28-year-old Caucasian woman presented with a 12 month history of secondary amenorrhoea, polyuria and polydipsia with fatigue and weight loss. Investigations revealed panhypopituitarism, diabetes insipidus, an intrasellar mass and papilloedema, thought to be due to benign intracranial hypertension. She was treated conservatively. However, a repeat magnetic resonance image showed enlargement of the pituitary mass with compression of the optic nerves. The pituitary abscess was drained by a transsphenoidal approach. Postoperatively the patient received antibiotics with no recurrence of the pituitary abscess. Copyright 1999 Harcourt Publishers Ltd.

The authors report a patient with a rare intrasellar meningioma mimicking pituitary adenoma. A 60-year-old man was admitted to our hospital for evaluation of general fatigue. He had no neurological deficit including visual function. Endocrinological tests revealed panhypopituitarism. The craniogram showed slight enlargement of the sella turcica with thinning of the dorsum sellae. CT scan and MR imaging demonstrated a homogeneously enhanced intrasellar mass with slight suprasellar extension. Partial removal of the mass was performed via the transsphenoidal approach because it was extremely firm and hemorrhagic. Histological diagnosis was transitional meningioma. The patient has been well for two years after surgery without tumor progression on MR imaging. It is mandatory to distinguish intrasellar meningioma from pituitary adenoma preoperatively because of marked difference in their treatment strategies. Despite recent advances in neurodiagnostic imaging, it may still be difficult to differentiate pituitary adenoma from intrasellar meningioma. When we re-evaluated the MR imaging, we recognized that the tumor had demonstrated specific findings, ruling out pituitary adenoma, namely bright and homogeneous enhancement, dense enhancement in the early phase on the dynamic MR study, and flow void signal within the mass. The authors emphasize that careful evaluations of MR imaging will allow the correct preoperative diagnosis in patients with intrasellar meningioma mimicking pituitary macroadenoma.

A 67-year-old man with generalized fatigue and weight loss developed hyponatremia. Endocrinologic examination demonstrated panhypopituitarism. Magnetic resonance imaging showed a pituitary mass extending slightly to the suprasellar region. Transsphenoidal resection of the tumor was performed. Histological examination found exclusively granulomatous tissue with cholesterol clefts, and no epithelial component. This cholesterol granuloma may be classified as xanthogranuloma of the sellar region.

In two patients, men aged 78 and 42 years respectively, an empty-sella syndrome was found. The first patient presented with chronic fatigue, in the second the empty sella was the late result of prior neurosurgery followed by external irradiation. Both suffered from panhypopituitarism. In both cases the diagnosis was confirmed following laboratory tests and MRI. Hormone-replacement therapy was found to provide adequate treatment. The course of the empty-sella syndrome is usually benign and with adequate hormone-replacement therapy a good quality of life is maintained.

We encountered a rare case of neurohypophyseal germinoma with a prominent granulomatous reaction, which invaded the right cavernous sinus. The neuroimaging and histopathology features in this case were unique, distinguishing it from other types of suprasellar lesions. A 13-year-old boy presented with loss of appetite and polyuria; both symptoms were present for 1 year, and headache, general fatigue and blurred vision present for the prior 2 months. On admission, neurological examination indicated bitemporal hemianopsia and optic atrophy. Endocrinological exam showed panhypopituitarism. Tumor markers such as alpha-fetoprotein, human growth hormone, carcinoembryonic antigen, and placental alkaline phosphatase were negative. Brain CT revealed a suprasellar tumor with calcification. MR T(1)-weighted and T(2)-weighted images showed the tumor to be isointense to normal brain parenchyma and to be enhanced densely. The tumor also involved the right cavernous sinus, so that a biopsy was performed by the transsphenoidal approach. On pathologic examination of the specimen, typical large tumor cells with lymphocytic cell infiltration and prominent granulomatous reaction were observed. Neurohypophyseal granulomatous germinoma was diagnosed. Radiotherapy was performed with a total dose of 51 Gy and the tumor shrank remarkably. The patient returned to school under hormone replacement therapy.
