Management of an incidentally found large adrenal myelolipoma: a case report

Abstract

Adrenal myelolipoma is a rare benign neoplasm composed of mature adipose and hematopoietic tissue. Most lesions are small, unilateral and asymptomatic, discovered incidentally at autopsy or on imaging studies performed for other reasons. We would like to present a case report of this rare tumour. Cross-sectional imaging is helpful in making a pre-operative diagnosis. The size of the lesion should be a criterion for surgical intervention.

Radiological and Pathological Findings in a Case of Large Left Adrenal Myelolipoma

“…It is composed of mature adipose tissue and haematopoietic elements. The reported incidence of adrenal myelolipoma varies from 0.08% to 0.4 % .The male to female ratio is 1:1 and are commonly found in the fifth to seventh decade [5]. Most of them are asymptomatic lesions and discovered incidentally.…”

“…They constitute 15% of adrenal incidentalomas because of frequent use of non invasive imaging techniques [6]. Occasionally, patients present with abdominal pain secondary to haemorrhage (more likely when it is predominantly composed of myeloid [5]. Very uncommonly, presenting symptoms include haematuria and abdominal mass [7].…”

Adrenal myelolipoma :Incidentally discovered mass

“…Adrenal myelolipomas are usually noted in fifth to the seventh decade of life, equally affect both sexes and with an incidence of 0.08-0.2%. Myelolipomas account for 3-5% of all primary tumours of adrenals [3][4]. Less than 300 cases were reported in the literature before 2000 [5].…”

Adrenal myelolipoma with keratoconus: A novel clinical association

“…The cause of this metaplasia is not well-known, but it is believed to be due to chronic adrenal stimulation by ACTH [congenital adrenal hyperplasia (CAH), Addison's disease, Cushing's syndrome], chronic infection, necrosis, stress, or exogenous steroid use. [1] They occur most commonly in fifth to seventh decade without any sex preponderance. [1] Keratoconus is the most common ectatic corneal disorder characterized by conical shape of cornea due to thinning of cornea as a result of degeneration, usually bilateral, leading to severe myopia and astigmatism.…”
