OBJECTIVE Patients undergoing pituitary adenoma or Rathke cleft cyst (RCC) removal are often administered perioperative glucocorticoids regardless of lesion size and preoperative adrenocorticotropic hormone/cortisol levels. To minimize unnecessary glucocorticoid therapy, we describe a protocol in which patients with normal preoperative serum cortisol and adrenocorticotropic hormone levels are g...
Adrenal tumors showing no clinical manifestations (incidentaloma) are frequently encountered during imaging analysis upon routine examinations. These tumors are sometimes associated with hypertension and/or diabetes mellitus (DM). We have examined six cases of incidentalomas with these symptoms in this study. All patients underwent endocrinological evaluation by measuring plasma cortisol and al...
BACKGROUND Adrenal aldosterone excess is the most common cause of secondary hypertension and is associated with increased cardiovascular morbidity. However, adverse metabolic risk in primary aldosteronism extends beyond hypertension, with increased rates of insulin resistance, type 2 diabetes, and osteoporosis, which cannot be easily explained by aldosterone excess. METHODS We performed mass ...
Adrenal myelolipomas are a variety of rare and endocrinologically non functional benign neoplasms the adrenal gland. They usually composed haematopoietic elements with interspersed areas fatty tissue, thus, resembling bone marrow tissue. These tumours detected as an incidentaloma during routine scans on suspicion other diagnoses mostly silent clinically. have always been subject diagnostic dile...
UNLABELLED A functional lesion in corticotrophin (ACTH)-independent Cushing's syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and (131)I-6β-iodomethyl-19-norcholesterol ((131)I-NP-59) scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholestero...
We describe a man without the clinical findings of Cushing's syndrome, but who harbored an incidentally found cortisol-producing adrenal adenoma. On adrenal 131I-adsterol imaging, there was good uptake to the nodule, but no visualization of the contralateral adrenal. No abnormalities were found in the basal plasma cortisol, ACTH, urinary free cortisol and 17OHCS. However, dynamic hormone assess...
BACKGROUND AND OBJECTIVE Adrenal tissue-sparing or partial adrenalectomy evolved initially for patients with bilateral synchronous adrenal surgical pathology to preserve vital adrenal volume. In the laparoscopic era, the exact criteria for performing such procedures laparoscopically have yet to be defined. Controversy exists regarding the importance of preserving the adrenal vein, main or acces...
A 38-year-old woman presented with “moon face,” “buffalo hump,” and weight gain of 9 kg in 12 months. Overnight, 1mg dexamethasone failed to suppress the morning level of cortisol, and the 24-hour urine cortisol level was elevated to 101μg/day (normal range 0–50). Initial contrast-enhanced abdominal computed tomography (CT) showed a 2.8-cm left adrenal mass enhanced in arterial phase, and the p...
Primary aldosteronism is the most common form of secondary hypertension with hypokalemia and suppressed renin-angiotensin system caused by autonomous aldosterone production. Our aim was to compare zona glomerulosa (ZG) structure and function between control adrenals and the peritumoral tissue from patients operated on for aldosterone-producing adenoma. ZG morphology and CYP11B1, CYP11B2, and di...
