A 40-year-old white woman presented with hirsutism, amenorrhea, generalized fatigue, diffuse weight gain, acral changes, and coarsened facial features. Physical examination revealed mild diastolic hypertension, acromegalic features, hirsutism, and seborrhea. The growth hormone concentration was elevated and did not suppress after glucose administration. Urinary free cortisol excretion was increased and was not suppressed during a 2 mg low-dose dexamethasone suppression test. Magnetic resonance imaging of the sella demonstrated a 1.3 x 1.2 x 0.8 cm pituitary adenoma. Trans-sphenoidal resection was performed, and portions of the resected tumor were analyzed by routine pathologic methods. Histopathologic and immunohistochemical findings indicated discrete growth hormone- and adrenocorticotropic hormone-producing pituitary adenomas. Coexisting acromegaly and Cushing's syndrome due to pituitary neoplasia was previously reported in two patients. However, to the authors' knowledge, this represents the first description of a patient with acromegaly and Cushing's disease resulting from discrete synchronous adenomas of the pituitary gland as defined by modern histopathologic techniques.

A rare case of simultaneous hypersecretion of thyroid stimulating hormone (TSH) and growth hormone (GH) in a pituitary adenoma is reported. A 59-year-old male complaining of general fatigue, dyspnea on exertion and finger tremor was admitted. Examination on admission, he revealed with hyperthyroidism and hypersecretion of TSH and thyroid hormones. Administration of TRH did not further increase serum TSH level, and administration of T3 also had no effect on TSH secretion. CT scan showed a pituitary macroadenoma 13mm in diameter. MRI demonstrated a homogenously hypointense mass with Gd-DTPA enhancement in the left side of the sella turcica. The entire chromophobic adenoma was removed by trans-sphenoidal surgery. Immunostaining of the specimen showed that the cytoplasm of the adenoma cells was positive for both TSH and GH. Double immunostaining using avidin-biotin-peroxidase complex (ABC) method and immunogold silver staining (IGSS) method, showed that the adenoma cells had been secreting both GH and TSH at the same time. After the adenomectomy, the hyperthyroidism disappeared, and all altered indicators of pituitary function returned to normal.

A 58-year-old woman was admitted to our hospital with complaints of general fatigue, thirst and lumbago. A diagnosis of Cushing's syndrome was made on the basis of elevated serum levels of cortisol and adrenocorticotropic hormone (ACTH). Although Cushing's disease was most suspected, no evident image of pituitary adenoma could be found on brain CT scan and MRI. Therefore, treatment with oral Trilostane was started. Three months after admission, left hemiplegia was noticed and cerebral abscess in the right frontal lobe was demonstrated by brain CT scan. In spite of surgical removal of the abscess by total resection, she had a relapse in the same site and also developed a new lesion in the left lateral lobe. Surgical drainage was performed and Nocardia asteroides was isolated from the drained pus. An intensive chemotherapy with aminobenzylpenicillin (ABPC) and latamoxef (LMOX) in combination resulted in marked decrease in size of the lesion in the brain and subsequent improvement of left hemiplegia was achieved. Since approximately one month before when a diagnosis of cerebral abscess was made, there had been demonstrated a coin lesion in the right middle field on chest X-ray films. This lesion in the right lung disappeared concomitantly with the improvement of the lesions in the brain. This fact strongly suggests that the lesion in both brain and lung were of the same nature. Nocardia is known to make a primary lesion in the lung after being inhaled and then through hematogenous dissemination to make distant lesions in various sites, especially in the brain.(ABSTRACT TRUNCATED AT 250 WORDS)

Lymphocytic adenohypophysitis is considered to be an inflammatory disease of the adenohypophysis that is commonly present with visual disturbance and hypopituitarism. Its etiology remains unclear but it is often related to an autoimmune disorder involving other organs, such as the thyroid, parathyroid, or adrenal glands. We encountered a rare case of lymphocytic adenohypophysitis associated with sarcoidosis of the lung and eye during the follow-up period. A 23-year-old woman was hospitalized in July 1986, with a one-month history of headache and visual disturbances which began three days after her second normal delivery. On admission, she showed slight visual impairment and had a left temporal superior quadrantanopia. Endocrinological evaluation revealed thyroid and adrenal hypofunction, and low response of human growth hormone to the loading test. A skull X-ray showed normal shaped sella with some erosion of the dorsum. CT scan showed a rounded contrast-enhanced intrasellar mass extending into the suprasellar cistern. MRI (SR: 500/30) showed a homogeneous low intensity mass which contained a small high intensity area on the relative T2-weighted image (2000/50). A biopsy was performed via right frontotemporal craniotomy. The consistency of the resected tissue was firmer than that of pituitary adenoma. Histologically, the tissue showed diffuse lymphocytic infiltration with some normal adenohypophysis. Her postoperative course was uneventful and the visual impairment improved two months later after the operation. Six months after the operation, she was readmitted with complaints of general fatigue and breathlessness. Chest X-ray showed diffuse infiltration throughout both lung fields, but there was no bilateral hilar lymphadenopathy.(ABSTRACT TRUNCATED AT 250 WORDS)

A surgical case of prolactinoma associated with craniopharyngioma is reported. A 47-year-old man was admitted to some neurosurgical clinic on October 12, 1982, because of visual disturbance, general fatigue and impotence. Laboratory study revealed hyperprolactinemia (360 ng/ml) and slight enlargement of sella turcica indicated the pituitary adenoma. Transsphenoidal surgery was performed to remove the tumor on November 20, 1982. Histopathological examination revealed chromophobe adenoma, and prolactin was stained in the tumor cells by means of immunoperoxidase staining. Though the clinical symptoms had been improved after surgery, visual disturbance became worse about one month later. At that time empty sella syndrome was suspected and the second operation (interhemispheric approach) was performed on January 21, 1983. No pathological changes were observed at all. On July 13, 1983, he was transferred to our clinic, because his visual acuity was deteriorating. At this time we reviewed the previous CT scan and noticed a suprasellar mass. It was supposed that the lesion had been overlooked and was the cause of the visual disturbance. On August 1, 1983, a bifrontal craniotomy was performed and the suprasellar tumor was removed. Pathological examination of the tumor revealed craniopharyngioma. So it was supposed that pituitary adenoma and craniopharyngioma had been coexisting since onset. Except for cases with von Recklinghausen's disease, multiple primary intracranial tumors of different cell types are relatively rare. A review of literature revealed 94 cases until 1986. The most frequent combination of multiple tumors was meningioma and glioma. But we could not find any case of pituitary adenoma associated with craniopharyngioma in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)

Pituitary abscess is relatively rare. Only about 80 cases have been reported. Preexisting lesions in pituitary fossa, such as pituitary adenoma, craniopharyngioma and Rathke's cleft cyst, are inclined to be complicated by infection more than the normal pituitary glands are. We reported a case of pituitary abscess caused by infection of Rathke's cleft cyst. A 67-year-old male had general fatigue and loss of appetite 4 months before admission. On admission he was found to have diabetes mellitus, diabetes insipidus, and hypernatremia. These defects were controlled by medication but he gradually became comatose and febrile. CT and MRI revealed an intrasellar lesion with ring enhancement. Lumbar puncture demonstrated an increase of mononuclear cells and protein. Blood chemistry revealed a marked increase of CRP. He was operated on via the transsphenoidal approach, which revealed sphenoid sinusitis and abscess formation in the pituitary gland. Histological examination of the surgical specimen revealed infection of Rathke's cleft cyst but the fluid in the cyst was sterile. By the drainage of the cyst and the use of antibiotics the patient became alert and signs of infection disappeared. He was discharged with a slight hypopituitarism and returned to normal life. Mortality rate of pituitary abscess is decreasing but is still high because of hypopituitarism and severe infection. Accurate diagnosis and operation are necessary. Transsphenoidal surgery is preferable for postoperative drainage of the abscess.

TSH-secreting pituitary adenoma with calcification and proliferation of the collagen fibers was presented. A 42-year-old man had shown general fatigue and thyroid hypertrophy caused by hyperthyroidism for 3 years. CT and MRI revealed pituitary adenoma with calcification extending into the cavernous sinus and sphenoid sinus. The patient was operated on using the transsphenoidal route twice, but the tumor was not able to be removed totally, partly due to the hardness of the tumor. The tumor in- and around the left cavernous sinus as well as the hardest part of the tumor itself due to the calcification could not be removed. Histopathological examination revealed chromophobe adenoma with proliferation of the collagen fibers. Immunohistological and electronmicroscopic examination demonstrated TSH-secreting adenoma. Postoperatively, thyroid function improved and the patient's symptoms due to hyperthyroidism disappeared.

Schmidt syndrome consists of adrenal insufficiency and Hashimoto's thyroiditis, which are probably caused by an autoimmune process. We encountered a patient who manifested severe generalized fatigue due to Schmidt syndrome recurrently. The endocrinological examination tests on the patient showed that the increase in thyroid stimulating hormone (TSH) and ACTH concentrations were not remarkable, despite hypo-function of the peripheral glands. Subsequent cranial magnetic resonance imaging (MRI) exhibited the existence of a pituitary tumor. The pathological findings on the resected tumor and endocrinological stimulation tests proved that the tumor was a FSH-producing adenoma. Although involvement of the pituitary region in Schmidt syndrome on rare occasions presents as hypophysitis, no pituitary adenoma has previously been reported in association with this syndrome. We present a patient with Schmidt syndrome and an accompanying FSH-producing pituitary adenoma. The coexistence of these disorders suggests that the functioning pituitary tumor might be considered as a pituitary lesion in Schmidt syndrome.

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.

Two patients, a woman aged 32 years and a man aged 49, presented with severe chronic fatigue. The woman had chronic fatigue syndrome; she recovered slowly. The man suffered from a pituitary adenoma producing follicle stimulating hormone; he recovered after transsphenoidal hypophysectomy. In patients with chronic fatigue, the history and a thorough physical examination to exclude underlying illness are very important; secondary symptom criteria must not be overemphasized (as is the case with the Holmes and Fukuda criteria), chronic fatigue syndrome should not be diagnosed if the condition has a shorter duration than 6 months, but it should be diagnosed if the clinical picture is compatible. The prognosis is not poor: in patients with a median disease duration of 4.5 years, 20% show significant improvement over an 18-month period.
