1/471. Primary aldosteronism with aldosterone-producing adrenal adenoma in a pregnant woman.A 30-year-old pregnant woman complained of muscle weakness at 29 weeks' gestation. She was hypertensive with severe hypokalemia. Lower plasma renin activity and higher aldosterone level than the normal values in pregnancy suggested primary aldosteronism. A cesarean delivery was performed at 31 weeks' gestation because of pulmonary congestion. The neonatal course was uncomplicated. The laparoscopic adrenalectomy for a 2.0-cm right adrenal adenoma resulted in normalizing of her blood pressure and serum potassium level. Although primary aldosteronism is rare, especially during pregnancy, it should be always considered as one of etiologies of hypertension in pregnancy.- - - - - - - - - - ranking = 1keywords = adrenal (Clic here for more details about this article) |
2/471. Adrenal cancer with hypertension but low plasma renin and aldosterone.patients with malignant lesions of the adrenal gland may present with a syndrome of excess mineralocorticoids. Both primary hyperaldosteronism and excess mineralocorticoids other than aldosterone resulting from adrenal carcinoma have rarely been reported. In most patients with adrenal tumors secreting mineralocorticoids other than aldosterone, distant metastasis had already occurred at the time of diagnosis and the prognosis was poor. We present a rare case of adrenal cancer with hypertension in a patient with low plasma renin activity and a low plasma aldosterone concentration. The patient's blood pressure returned to normal after removal of the tumor. The patient is still alive and without recurrence 6 years after surgery. This case illustrates the value of thorough evaluation of hypertension and prompt surgical treatment for patients with adrenal cancer.- - - - - - - - - - ranking = 0.84827172349969keywords = adrenal, adrenal gland, gland (Clic here for more details about this article) |
3/471. ventricular fibrillation: an extreme presentation of primary hyperaldosteronism.patients with primary aldosteronism often present with hypokalemia and hypertension. Primary aldosteronism presenting as sudden death due to ventricular fibrillation is described in an otherwise healthy 37-year-old woman. After successful direct current cardioversion, serum potassium was 1.4 mmol/L. Investigations revealed a suppressed renin level, elevated serum aldosterone and a right adrenal nodule found on imaging. ventricular fibrillation has not previously been described as a presention of a biochemically and surgically proven aldosterone-producing adenoma. This case highlights the importance of early detection and proper diagnosis of secondary hypertension before serious sequelae occur.- - - - - - - - - - ranking = 0.16666666666667keywords = adrenal (Clic here for more details about this article) |
4/471. A rare combination consisting of primary hyperaldosteronism and glucagonoma.A 59-yr-old man with multiple pancreatic tumors is presented. Previously, he had undergone left adrenalectomy for primary hyperaldosteronism and left nephrectomy for renal cell carcinoma at the ages of 39 and 55 yr, respectively. This time, 3 yr after removal of renal cancer, two solid lesions in the pancreas associated with hyperglucagonemia were detected. Under a diagnosis of pancreatic metastasis from renal cell carcinoma or islet cell tumor of the pancreas, distal pancreatectomy with splenectomy and enucleation of the tumor in the pancreas head were performed. Microscopically, a glucagonoma, measuring 2.3 mm in diameter, was detected among five pancreatic metastases from renal cell carcinoma. Four years after surgery, the patient remains well, without signs of recurrence despite multiple pancreatic metastases. This is the first report of such a rare combination consisting of aldosterone-secreting adrenal adenoma and glucagonoma.- - - - - - - - - - ranking = 0.33333333333333keywords = adrenal (Clic here for more details about this article) |
5/471. 11-Deoxycorticosterone-producing adrenocortical carcinoma.A woman presented with a history of weight loss and muscle weakness. A laboratory test revealed hypokalemia and elevation of plasma 11-deoxycorticosterone (DOC). CT showed a left adrenal mass. A left adrenalectomy was performed. The histological and immunohistochemical diagnosis showed a DOC-producing adrenocortical carcinoma. This cancer is very rare; only 10 cases including the present case have appeared in the literature.- - - - - - - - - - ranking = 0.33333333333333keywords = adrenal (Clic here for more details about this article) |
6/471. Adrenocortical oncocytoma.The histopathology and ultrastructural features of an adrenocortical oncocytoma are reported. The tumour was discovered incidentally during investigation for hypertension in a 72 year old female. Oncocytic tumours of the adrenal cortex are rare, with only 20 examples described in English language reports. Most have been non-functioning and benign, like the present example. Molecular studies may help assess the significance of oncocytic change in the pathogenesis and behaviour of oncocytic neoplasms.- - - - - - - - - - ranking = 0.16666666666667keywords = adrenal (Clic here for more details about this article) |
7/471. Paroxysmal tachycardia and hypertension with or without ventricular fibrillation during laparoscopic adrenalectomy: two case reports in patients with noncatecholamine-secreting adrenocortical adenomas.We present two cases of sudden unanticipated cardiovascular complications in patients with noncatecholamine-secreting adrenocortical adenomas during laparoscopic adrenalectomy. In the first case, the patient developed paroxysmal tachycardia and hypertension followed by ventricular fibrillation shortly after clipping of the adrenal vein. In the second case, the patient suffered hypertension and bigeminy during manipulation of the adrenal gland just around the adrenal vein. awareness of such complications during either conventional or laparoscopic adrenalectomy is important even if the operation is performed in a patient with an apparently noncatecholamine-secreting adrenocortical adenoma.- - - - - - - - - - ranking = 1.5149383901664keywords = adrenal, adrenal gland, gland (Clic here for more details about this article) |
8/471. A patient with preclinical Cushing's syndrome and excessive DHEA-S secretion having unilateral adrenal carcinoma and contralateral adenoma.We report a case of preclinical Cushing's syndrome in a 54-year-old male associated with bilateral adrenocortical tumours. Physical findings and general laboratory data were unremarkable except for mild hypertension (158/90 mmHg) and impaired glucose tolerance. Endocrinological evaluation revealed the presence of autonomous cortisol secretion including unsuppressible serum cortisol by 8 mg dexamethasone test (11 microg/dl), high serum DHEA-S (3580 ng/ml, normal: 400-3500) and increased urinary 17-KS excretion (31.0-35.8 mg/day, normal: 5.8-21.3). CT scan demonstrated the presence of tumours in both adrenals and bilateral adrenalectomy was subsequently performed. Histological examination of the resected specimens revealed an adrenocortical carcinoma on the right side and an adenoma on the left side with noticeable cortical atrophy in non-neoplastic adrenals. Immunohistochemical study of steroidogenic enzymes demonstrated that all the steroidogenic enzymes involved in cortisol biosynthesis were expressed in both right and left adrenal tumours. Enzymatic activities of 21, 17alpha, 18, 11beta-hydroxylases were detected in both right and left adrenals except for the absence of 11beta-hydroxylase activity in the left adrenal adenoma. Results of in vitro tissue steroidogenesis examined in short-term tissue culture of the specimens revealed no significant differences between carcinoma and adenoma in cortisol production, but the production of adrenal androgens in carcinoma was significantly higher than that in adenoma, which may indicate the importance of evaluating adrenal androgen levels in patients with adrenocortical neoplasms.- - - - - - - - - - ranking = 2keywords = adrenal (Clic here for more details about this article) |
9/471. A case of acromegaly accompanied by adrenal preclinical Cushing's syndrome.We encountered a 58-year-old woman with acromegaly accompanied by a cortisol-secreting adrenal tumor without clinical features of hypercortisolism. The simultaneous occurrence of these two endocrinopathies in one individual is extremely rare. She was diagnosed as having diabetes mellitus 8 years ago. Afterwards, in spite of insulin therapy, her hyperglycemia could not be well controlled. Her acromegaly and preclinical Cushing's syndrome were histopathologically proven to be due to a pituitary adenoma and an adrenocortical adenoma, respectively. Successful treatment for these endocrinopathies resulted in greatly improved blood sugar control because of a reduction in insulin resistance. In this case of preclinical Cushing's syndrome, replacement therapy with glucocorticoid was able to be discontinued at only 8 weeks after adrenalectomy, so that the period of necessary replacement was much shorter than that for overt Cushing's syndrome. This is the first report describing insulin resistance before and after treatment in a case of acromegaly accompanied by adrenal preclinical Cushing's syndrome.- - - - - - - - - - ranking = 1.1666666666667keywords = adrenal (Clic here for more details about this article) |
10/471. Clinics in diagnostic imaging (39). Conn's syndrome due to adrenocortical adenoma (Conn's tumour).A 33-year-old man presenting with muscle weakness and hypertension was found to have hypokalaemia and metabolic alkalosis. Computed tomography (CT) showed an adrenal mass. Conn's syndrome due to an adrenocortical adenoma was confirmed at surgery. hypertension-related adrenal disorders such as Cushing's syndrome, carcinoma and phaeochromocytoma are discussed. CT is currently the single most useful imaging method for identifying adrenal masses.- - - - - - - - - - ranking = 0.5keywords = adrenal (Clic here for more details about this article) |
