A case of intrasellar and suprasellar meningioma with hypopituitarism is reported. A-64-year-old woman was admitted to our hospital with chief complaints of reduced consciousness and inactivity. She had a history of subarachnoid hemorrhage 20 years previously, and developed right third nerve palsy. Physical examination demonstrated that, in consciousness, she was stuporous, and she had impaired visual acuity and palsy in the right third nerve. An X-ray film of the sella turcica showed enlargement and intrasellar calcification. A CT scan with contrast enhancement revealed a homogenously enhanced mass in the sella and suprasellar region. A cerebral angiogram showed elevation of the bilateral A1 portion of the anterior cerebral artery. No tumor blush was evident. Endocrinologic function tests confirmed impaired anterior lobe hormones and hypothyroidism. Preoperative diagnosis was pituitary adenoma. The tumor was subtotally removed by using the transsphenoidal approach and right frontotemporal craniotomy was carried out using microsurgery in a two staged operation. The tumor was yellowish-grey, partly firm in consistency, and it had a soft elasticity. Operative findings showed that the dura matter of the tuberculum sella, the anterior and posterior clinoid process, the medial sphenoidal ridge, and the wall of the cavernous sinus were intact, which was confirmed at autopsy, later. Microscopical examination revealed a mixed meningothelial and fibroblastic meningioma with papillary component and psammomatous bodies. The tumor was thought to originate in the diaphragma sella, and to extend in intrasellar and suprasellar directions. The patient died of basilar artery thrombosis. In clinical and radiological examination, there is no definite difference between pituitary adenoma and intrasellar meningioma.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of pituitary apoplexy causing pituitary hemorrhage with extension into the third ventricle is reported. The patient was a 73-year-old, obese female admitted with sudden onset of vomiting and impaired consciousness. Neurological examination revealed that she was stuporous, with marked neck stiffness and a dilated left pupil. A plain skull X-ray showed sellar enlargement and destruction of the dorsum sellae. Computed tomography demonstrated a high-density area in the third and lateral ventricles and a round, high-density mass in the suprasellar cistern. The patient died the next day. Autopsy revealed a large tumor in the sellar and suprasellar areas. The tumor and the hematoma within it compressed the floor of the third ventricle and passed through the lamina terminalis and the hypothalamic region. Histological examination disclosed a basophilic adenoma. The pituitary hemorrhage appeared to be the result of ischemia and necrosis within the pituitary adenoma caused by its acute expansion. The extension of the hematoma into the third ventricle was attributable to the large size of the tumor and its close adhesion to the floor of third ventricle.

Hyperadrenocorticism was diagnosed in 7 cats with concurrent diabetes mellitus. Four cats had pituitary adenoma with bilateral adrenocortical hyperplasia, 1 cat had pituitary carcinoma with bilateral adrenocortical hyperplasia, 1 cat had adrenocortical carcinoma, and 1 cat had adrenocortical adenoma of the left adrenal gland. One year later, adrenocortical adenoma involving the right adrenal gland also was diagnosed in this cat. Clinical signs included polyuria and polydipsia (n = 7), development of pot-bellied appearance (n = 5), dermatologic alterations (n = 5), lethargy (n = 3), weight loss (n = 3), dyspnea/panting (n = 2), and recurrent bacterial infections (n = 2). In 6 cats, the diagnosis of hyperadrenocorticism was established before death on the basis of results of the ACTH stimulation test (n = 3) and the dexamethasone screening test (n = 5). Pituitary-dependent hyperadrenocorticism was differentiated from adrenocortical neoplasia on the basis of results of the dexamethasone suppression test (n = 4), endogenous ACTH concentration (n = 3), results of abdominal radiography and ultrasonography (n = 3), and exploratory celiotomy (n = 1). Four cats died or were euthanatized without treatment attempts. Treatment with mitotane followed by 60Co teletherapy was ineffective in one cat with pituitary adenoma. One cat with pituitary carcinoma died one week after bilateral adrenalectomy. Bilateral adrenocortical adenomas were removed surgically in the affected cat.

The association of pituitary adenoma and adjacent cerebral aneurysm is not uncommon and acute hemorrhage into a pituitary adenoma is also a well recognized condition. However, the simultaneous occurrence of pituitary apoplexy with intracranial aneurysm is very rare. Such a case demonstrates the diagnostic difficulty in distinguishing between pituitary apoplexy and rupture of an aneurysm. We reported a patient with subarachnoid hemorrhage in whom a hemorrhage into the pituitary adenoma and a carotid-ophthalmic aneurysm was proven, and discussed the differential diagnosis and treatment. A 41-year-old man, who developed sudden severe headache with nausea and vomiting, was admitted to our hospital. Examination disclosed a mildly stuporous man with bilateral defects of upper lateral visual fields and lumbar puncture revealed subarachnoid hemorrhage. Plain radiographs of the skull showed an enlarged and eroded sella turcica. Carotid angiography revealed a left carotid-ophthalmic aneurysm. A plain CT scan demonstrated an acute suprasellar hematoma. A transsphenoidal operation was performed and postoperative course was uneventful.

Reported herein is the possible interaction between two drugs used to treat a man with a large prolactin-secreting pituitary adenoma. The patient had a long history of schizophrenia that was treated with many different medications, including phenothiazines. Evaluation of progressive lethargy led to the discovery of a large parasellar tumor and a prolactin level of 7,981 ng/ml. His serum prolactin level fell to the 400 ng/ml range during bromocriptine therapy but rose whenever the antipsychotic thioridazine was added to his regimen. A marked deterioration of his visual fields was noted after 3 months' therapy with both drugs, and this abnormality resolved five days after the thioridazine was stopped. The use of dopamine antagonists such as thioridazine in patients with prolactinoma may interfere with bromocriptine's action, resulting in potentially serious complications.

From the literature and our own experience, 11 cases of hemorrhage or infarction of a pituitary adenoma associated with cardiac surgery have been identified over a 13-year period. Males outnumbered females by 10 to 1. Symptoms observed were headache, lethargy, confusion, obtundation, unilateral ptosis, meiosis, and opthalmoplegia involving cranial nerves III, IV, and VI, visual field deficits, and hemiparesis. Diagnosis in most recent cases has been confirmed with computerized tomography or magnetic resonance imaging. All patients received adrenocortical steroid therapy initially. Eight patients underwent transsphenoidal hypophysectomy and all survived. One patient underwent decompression craniotomy and died. Intracranial surgery was deferred in 1 patient who survived and in another who died of a massive stroke. Residual neurological deficits were noted to be either absent, minimal, or resolving in 7 of the 9 patients who survived their initial hospitalization. While numerous mechanisms have been proposed to explain the hemorrhage and necrosis of a pituitary adenoma during heart surgery, no direct cause has been clearly identified. Surgical treatment is commonly necessary since untreated pituitary apoplexy is often fatal. Transsphenoidal hypophysectomy with decompression is the preferred method of treatment with a low perioperative mortality and fairly good long-term prognosis.

Two men undergoing transsphenoidal exploration for pituitary adenoma were found to have lymphocytic hypophysitis. Both presented with frontal headaches, lethargy, and diminished libido. Laboratory investigations showed markedly depressed serum testosterone, and magnetic resonance imaging demonstrated pituitary enlargement, with optic chiasm involvement. Intraoperatively, the dura was adherent to the pituitary in each case. The resected glands were effaced by a dense lymphoplasmacytic infiltrate and fibrosis, without granulomas. Nonspecific peripheral enhancement on imaging suggested a diagnosis other than adenoma, but more experience with peripheral enhancement in lymphocytic hypophysitis is needed. The diagnosis was histological and required surgical intervention. Long-term pituitary replacement therapy is usually required.

We describe a patient who initially presented with impotence followed by progressive lethargy and visual disturbances. Endocrine and radiological evaluation was suggestive of pituitary adenoma but pathological evaluation after transsphenoidal hypophysectomy revealed renal cell carcinoma metastatic to the pituitary. The etiology of this unusual presentation and prior reports of renal cell carcinoma spread to the pituitary are reviewed.

A 16 year female with a history of developmental delay and shunted hydrocephalus presented with two months of progressive headaches, lethargy and visual disturbances. An MRI of the brain revealed a sellar and suprasellar cystic mass which was absent on a previous MRI six years earlier. The pre-operative clinical diagnosis was pituitary adenoma vs. craniopharyngioma. Histologically, the fibrous wall of the ciliated epithelial-lined cyst was thickened by non-caseating granulomatous inflammation, hemorrhage, hemosiderin, and cholesterol clefts, consistent with cyst rupture. Rathke's cleft cysts are uncommon symptomatic lesions in young people, and must be distinguished from craniopharyngioma.

To evaluate the frequency of clinical manifestations and to study the etiological aspects of hypothyroidism in hypothyroid patients in Cotonou, we carried out a retrospective analysis of the medical reports on hypothyroid patients followed in our clinical practice. A total of 33 patients was thus studied, comprising 8 men (24%) and 25 women (76%) with mean age of 45,8 years for men and 40,4 years for women. The more frequent clinical manifestations observed were: face edema (45%), weight gain (45%), paresthesia (42%), fatigue (39%), lethargy (30%) and bradycardia (24%). Constipation (12%), sensation of cold (9%), depilation (6%) and dry skin (6%) were less frequently observed. Myalgia, hoarseness and menstrual irregularities were present in 15% of the cases respectively. Regarding the etiology, 82% of the cases were primary hypothyroidism and only 18% were of central origin. Thyroidectomy was the leading cause in our hypothyroid patients, representing 70% of all cases and 85% of primary hypothyroidism. Radioiodine treatment and autoimmune thyroiditis were equally found in 6% of the cases. Central hypothyroidism was related to a pituitary adenoma in four cases (12%) and to Sheehan syndrome in two cases (6%). As it can be expected, hypercholesterolemia was present in 82% of the patients but creatine phosphokinase elevation was more frequent (94% of the patients). Compared to the data reported in the literature, the frequency of the symptoms and signs of hypothyroidism seems to be underevaluated in our study and the frequency of autoimmune thyroiditis as a cause of hypothyroidism is low.
