Magnetic resonance imaging of the adrenal glands.

Applications of nuclear magnetic resonance (NMR) to the adrenal gland have received considerable attention in recent years. Using high field strength magnets and surface coil technology, images of normal and abnormal adrenal glands have been obtained that compare favorably, and in some instances excel, computed tomography (CT) with respect to both image quality and, to a greater degree, differentiation of pathology. This article reviews the current state of magnetic resonance (MR) imaging of normal and abnormal adrenal glands, compares MR with CT imaging, and indicates where NMR spectroscopy has been of greatest value to date in the study of adrenal gland disease.

The role of the adrenal gland in hypertension.

The adrenal gland plays a unique role in the etiology of many forms of hypertension. Recognizable syndromes of adrenal gland disease in which hypertension is observed can be identified and localized to each of the functional and histologic divisions of the adrenal cortex and medulla. The diagnosis of the various syndromes of adrenal hormone excess is a critically important first step in the successful identification, localization, and treatment of adrenal gland disorders.

Videoendoscopic adrenalectomy: multicentric study from the Belgian Group for Endoscopic Surgery (BGES).

This paper reports the experience of five Belgian surgical teams with 18 videoendoscopic adrenalectomies performed on 16 patients between October 1993 and May 1995. The adrenal gland diseases were pheochromocytoma (4 patients), primary hyperaldosteronism (2 cases), Cushing's adenoma (2 cases), Cushing's disease (1 case), nonfunctional adenoma (3 cases), single metastasis from adenocarcinoma (2 cases), functional adenoma with dehydro-epiandrostenedione (DHEAS) and cortisol hypersecretion (1 case), ACTH secreting metastases from a thymoma (1 case) Two patients underwent bilateral adrenalectomies. Eleven left and three right adrenal glands were removed in 14 other patients. The eight women and eight men range in age from 17 to 72 years (median 47). Six patients demonstrated a body mass index greater than 30. Median tumor size was 3 cm (range 1.3 - 5). Laparoscopic adrenalectomy was successful in 14 patients (87%). The median duration of the procedure was 132 minutes (range 59-360). The median postoperative stay was 6 days (range 2-13). No patient required blood transfusion. We conclude that the videoscopic approach can safely be used for surgical removal of adrenal lesions. However this approach should be performed by surgeons well versed in the techniques of open adrenalectomy for endocrine disorders, but also well trained in videoendoscopic surgery.

Tuberculous Addison's disease. Utility of CT in diagnosis and follow-up.

The computed tomographic (CT) findings in five patients with tuberculous Addison's disease were evaluated. All patients had extra-adrenal tuberculosis. Two patients had enlarged adrenal glands with calcifications at the times of diagnosis. Follow-up CT from 4 to 30 months showed a progressive decrease in the size of adrenal glands from bilateral enlargement to small calcified glands and provides a clue to the etiology of Addison's disease and proper therapy.

Early experience with laparoscopic approach for adrenalectomy.

BACKGROUND: Adrenalectomy performed by a posterior or transabdominal approach causes substantial postoperative pain. The purpose of this study was to evaluate laparoscopy as a potential approach for adrenalectomy. METHODS: We performed 25 consecutive laparoscopic adrenalectomies on 22 patients from April 1, 1992, to March 30, 1993. Laparoscopic surgery was performed by using a lateral decubitus flank approach with four 11 mm trocars. RESULTS: Twelve right and 13 left adrenal glands were removed in a mean time of 2.3 hours. Three patients underwent bilateral adrenalectomies in a mean time of 5.3 hours. The 15 women and 7 men range in age from 31 to 60 years (mean, 42 years). The adrenal gland diseases were nonfunctional adenoma (seven), pheochromocytoma (five), Cushing's disease (four), Cushing's adenoma (four), primary aldosteronism (two), dehydroepiandrostenedione sulfate hypersecretion (one), angiomyolipoma (one), and medullary cyst (one). Average tumor size was 4.1 cm (range, 1 to 15 cm). Laparoscopic adrenalectomy was successful in 96% of patients, with one patient requiring a laparotomy because of inadequate exposure. The median postoperative stay was 4 days (range, 2 to 19), with a mean of five narcotic injections. There were no deaths, and morbidity was minor. CONCLUSIONS: Laparoscopy can be used successfully for adrenalectomy. It produces less postoperative pain and rapid return to normal activity. It may be the preferred method for removing most adrenal gland lesions that require operation.
