1/98. 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 = adenoma (Clic here for more details about this article) |
2/98. 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 = 0.2keywords = adenoma (Clic here for more details about this article) |
3/98. 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 = 0.2keywords = adenoma (Clic here for more details about this article) |
4/98. Excessive concern with physical appearance leading to a diagnosis of adrenal adenoma.We report an unusual case of Cushing's syndrome manifested by anxiety over body image in a 26-year-old nurse. Initial presentation was a 'dermatological non-disease'. Clinical signs became increasingly evident during the course of the disease, justifying an adrenal gland evaluation which showed a secreting adrenocortical adenoma. Surgical treatment led to recovery with return to normal appearance and cessation of her aesthetic complaints. Our observation shows that persistent aesthetic complaints may sometimes reveal early hypercorticism.- - - - - - - - - - ranking = 1keywords = adenoma (Clic here for more details about this article) |
5/98. 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 = 1keywords = adenoma (Clic here for more details about this article) |
6/98. Primary aldosteronism caused by aldosterone-producing adenoma in pregnancy--complicated by EPH gestosis.pregnancy in conjunction with primary aldosteronism is an unusual occurrence. We report a 28-year-old woman who presented with mild hypertension and hypokalemia as manifestations of primary aldosteronism caused by an aldosterone-producing adenoma in the left adrenal gland during pregnancy. Although the diagnosis was straightforward, the patient refused to undergo the proposed operation during the second trimester of her pregnancy. She was not admitted to hospital until she developed EPH gestosis in the 27th week of gestation, which had an unfavourable outcome for the infant who died nine days after delivery. The patient underwent a laparoscopic adrenalectomy which resulted in normalization of blood pressure and blood potassium levels. In cases of aldosterone-producing adenoma, surgery in the second trimester is the most appropriate option to avoid a poor obstetric outcome.- - - - - - - - - - ranking = 1.2keywords = adenoma (Clic here for more details about this article) |
7/98. Peritoneal carcinomatosis following laparoscopic resection of an adrenocortical tumor causing primary hyperaldosteronism.A clinical syndrome combining hypertension and hypokalemic alkalosis led to the diagnosis of primary hyperaldosteronism, caused by a right-sided, 2 cm large, apparently benign aldosterone-producing adenoma. The adrenal tumor was completely resected by laparoscopic adrenalectomy. Six months after surgery, the patient exhibited a severe relapse of hyperaldosteronism. Extensive peritoneal metastases of a mixed aldosterone- and cortisol-secreting adrenocortical carcinoma were found at abdominal laparotomy. In the light of this case report, we discuss the possibility that laparoscopic resection of adrenocortical tumors might contribute to their subsequent peritoneal dissemination.- - - - - - - - - - ranking = 0.2keywords = adenoma (Clic here for more details about this article) |
8/98. recurrence of adrenal aldosterone-producing adenoma.Conn's syndrome (adrenal aldosterone-producing adenoma) and bilateral adrenal hyperplasia are the most common causes of primary aldosteronism. The treatment of choice for patients with aldosterone-producing adenoma is unilateral total adrenalectomy. recurrence after adequate surgery is exceptional. We present a patient with recurrence of an aldosterone-producing adenoma in the right adrenal gland 9 years after adenomectomy of a aldosterone-producing adenoma in the same adrenal gland. We conclude that adenomectomy is not an adequate therapy for patients with adrenal aldosterone-producing adenoma.- - - - - - - - - - ranking = 1.8keywords = adenoma (Clic here for more details about this article) |
9/98. A child with adrenocortical adenoma accompanied by congenital hemihypertrophy: report of a case.We report herein the findings of a 7-year-old male child with a ruptured adrenocortical adenoma and congenital hemihypertrophy which was incidentally detected after suffering a trauma. A review of 21 pediatric cases of adrenocortical neoplasms in the literature was made. The patient showed precocious puberty such as pubis and advanced bone age, but an endocrinological examination revealed no definite abnormalities. The right adrenal tumor with hematoma was resected after these evaluations. adrenocortical adenoma is considered to occur more frequently in female children. However, the incidence of adrenocortical tumors accompanied by congenital hemihypertrophy does not differ between males and females. The outcomes were relatively good, although the observation periods were short in some patients. A large number of patients presented with a tumor and hemihypertrophy on the same side. This finding is of interest when considering the possible association between hemihypertrophy of the organs and tumor proliferation. However, their association in terms of development was unclear. It is necessary for patients with hemihypertrophy to have regular examinations for the possible development of malignant tumors, especially in the kidney, adrenal gland, and liver.- - - - - - - - - - ranking = 1.2keywords = adenoma (Clic here for more details about this article) |
10/98. testosterone-producing adrenocortical neoplasm in a 6-year-old boy.Adrenal tumours that predominantly secrete testosterone are virtually unknown in prepubertal male patients.We present the case of a 6-year-old boy with premature sexual development and markedly elevated serum testosterone, but normal urinary steroid levels. diagnostic imaging demonstrated a spherical tumour of the left adrenal gland. Surgical excision led to normalisation of testosterone levels, and postoperative serial low hormone measurements ruled out tumour recurrence.Although extremely rare, this case illustrates that testosterone-producing adrenal adenomas may be encountered in boys without urinary steroid elevation. Surgical excision promises a definite cure. testosterone is a useful tumour marker in these patients until the beginning of puberty.- - - - - - - - - - ranking = 0.2keywords = adenoma (Clic here for more details about this article) |
