Myelolipomas and other fatty tumours of the adrenals.

Khater N, Khauli R - Arab J Urol (2011)

Bottom Line: We reviewed 45 articles, that confirmed, with a high level of evidence-based medicine, that the diagnosis of a lipomatous adrenal tumour is made by various imaging procedures, particularly computed tomography (CT).We emphasise the importance to their management of the initial size of the adrenal mass, its increase in size over time, in addition to the presence of symptoms.The diagnosis is usually made by various techniques, in particular CT.

ABSTRACT

Background: Lipomatous tumours of the adrenals are almost always benign. The importance of recognising their characteristic radiological features, leading to their correct treatment, is fundamental, as there has been an increase in the identification of these lesions. Our goal was to review all lipomatous tumours of the adrenal glands, particularly myelolipomas, their imaging methods and surgical management, updated in 2011.

Methods: This was a retrospective review of articles published in the USA and Europe, from 1979 to date. The sites from which information was retrieved covered PubMed, Medscape, Clinical Imaging, Histopathology, Urologia Internationalis, Archives of Surgery, JACS, the American Urological Association, BMJ, Medline, and Springer Link. We report areas of controversies in addition to well established guidelines.

Results: We reviewed 45 articles, that confirmed, with a high level of evidence-based medicine, that the diagnosis of a lipomatous adrenal tumour is made by various imaging procedures, particularly computed tomography (CT). We emphasise the importance to their management of the initial size of the adrenal mass, its increase in size over time, in addition to the presence of symptoms.

Conclusion: Lipomatous tumours of the adrenals are most frequently benign. The diagnosis is usually made by various techniques, in particular CT. The fundamental characteristics indicating the necessity of surgical intervention are the symptoms presented, volume of the tumoral mass (>5 cm), and the increase in size of the tumour as shown in two consecutive imaging studies.

f0015: US image showing a right 8.8 cm adrenal myelolipoma in a 51-year-old woman.

Mentions: US (Fig. 3) is a satisfactory method for detecting adrenal lesions, in particular if located in the right side where the adrenal gland is better visualised. The findings are of a mixed structure; intermediary because of the tissue components and typically hyperechogenic due to fat [25]. The fat appears definitely hyperechogenic in angiomyolipomas, but it is frequently minimally echogenic for the adjacent adipose cellular tissue in the other histological types.
