Adrenal hyperplastic and degenerative changes in beluga whales.

Thirty stranded beluga whales (Delphinapterus leucas) from the St. Lawrence Estuary (Quebec, Canada) population and five animals from the Hudson Bay aboriginal hunt (North-west Territories, Canada) were examined. Twenty one animals from the St. Lawrence Estuary had mild to severe adrenal lesions and four whales from the Hudson Bay population were affected by minimal adrenal changes. Cortical hyperplasia was observed in 24 adult beluga whales all from the St. Lawrence Estuary. Bilateral cortical cysts and cellular vacuolar degeneration were observed in the adrenal glands of 19 beluga whales from both populations. The cysts, filled with a cortisol-rich liquid, were present in both sexes. Beluga whales with adrenal cysts were significantly older than animals without cysts, and the severity of the lesions increased with age. Nodular hyperplasia of the medulla was observed in seven of the beluga whales, all from the St. Lawrence Estuary population. All lesions could be part of a normal aging process. The adrenocortical lesions might be due to stress or adrenocorticolytic xenobiotics, while the medullary hyperplasia might be caused by hypoxia or exposure to estrogenic xenobiotics.

High-resolution real-time sonography of the adrenal glands: a routine examination?

The feasibility of imaging the adrenal glands during routine upper abdominal examinations was studied for 100 consecutive patients, 47 males and 53 females. The mean patient age was 46 years and the mean weight 63 kg. The suprarenal areas were scanned in a slightly oblique frontal plane through the intercostal spaces with the patient recumbent. The right adrenal gland was detected in 92 per cent of the patients, with a mean examination time of less than one minute. Visualization of the left adrenal gland was more difficult and was successful in only 71 per cent, even where additional views in the right lateral decubitus or erect position were added. The mean examination time on the left was 2 1/2 minutes. Complete visualization of the adrenal gland is impossible in one single plane because of the complex shape of the organ, which necessitates multiple contiguous scan planes. In 13 per cent of the visualized adrenals, cortex and medulla could be differentiated.

[An adrenal pseudocyst. A report of a new case].

We report the case of a female young woman with an incidental cystic lesion in the left adrenal gland while during a routine study by her gynecologist. The change of the aspect in the content of the lesion, its limit size and a not definitive study of punction went to the surgical act. This was made with preservation of both, adrenal and renal units. The pathological report was adrenal pseudocyst.

[Adrenal cyst].

A case is described of adrenal cyst removed by surgical means. The above-named cyst might be related to a damage to the adrenal gland or congenital small cyst. Following the large cyst removal, the small one began to progressively enlarge.

[Vascular cysts of the adrenals. Association with aneurysm of the abdominal aorta].

A rare case of an adrenal vascular cyst associated to an abdominal aorta aneurysm is reported. Adrenal cysts are an uncommon clinical finding, in most cases incidentally discovered for nonspecific abdominal pain, during US, TC or RM evaluation or at autopsy. Small adrenal mass are clinically silent. They may be symptomatic (lumbar tension, pain) for dimensions over 10 centimetres. Cysts of large size can cause displacement and compression of adjacent organs. They present a difficult problem of differentiation between benign and malignant lesions. Non-neoplastic adrenal cysts have been divided into four categories: parasitic (7%), epithelial (9%), endothelial (45%) and haemorrhagic or pseudocystic (39%). Vascular adrenal cysts may be a traumatic consequence of an hamartomatous vascular anomaly. The aim of this paper is to discuss, on the basis of the literature, the etiology, diagnosis and treatment of the adrenal mass. Surgical timing is discussed for the concomitant vascular lesion. The elective treatment was left adrenalectomy performed through transperitoneal approach. Surgery for abdominal aorta aneurysm was differed because the adrenal mass was suspected to be an infected neoplastic lesion and for the feasibility of endovascular procedure. The adrenal specimens contained a cystic structure with fluid blood, fibrin and calcifications. Normal adrenal cortical tissue was found in the cystic wall. This lesion (arising from vascular anomalies) require separation from haemorrhagic adrenal neoplasm. Awareness of adrenal pseudocysts and careful attention to the hystological features aids this distinction.

Single-dose metyrapone test: review of a four-year experience.

Subnormal plasma 11-deoxycortisol (compound S) responses to metyrapone were found in patients with adrenal insufficiency or with Cushing syndrome caused by adrenal tumors and in those receiving long-term glucocorticoid or diphenylhydantoin sodium therapy. High normal or exaggerated responses were seen in women receiving oral contraceptives, patients with Cushing syndrome caused by adrenal hyperplasia, and those with untreated hypothyroidism. Diabetes mellitus, hypoglycemia, congestive failure, and obesity also were associated with exaggerated responses. Subnormal plasma S responses were observed in 15 patients who responded normally to a repeat test or to the standard metyrapone test. The abnormal response resulted from insufficient metyrapone, administration at the wrong time, or delay in obtaining the blood sample. The single-dose metyrapone test may be the procedure of choice in screening for adrenal insufficiency.
