Myelolipoma of Kidney: A Rare Extra-Adrenal Tumor in an Unusual Site.

Int J Appl Basic Med Res 2021 Jan-Mar;11(1):60-62. Epub 2021 Jan 26.

Department of Urology, Muljibhai Patel Urological Hospital, Nadiad, Gujarat, India.

Myelolipoma of the kidney is a very rare benign disease which is composed of mature adipose tissue admixed with mature hematopoietic elements in varying proportions. The most common location of myelolipoma is in the adrenal glands, but extra-adrenal myelolipomas in other locations such as the retroperitoneum, presacral region, pelvis, and mediastinum has also been reported. In this case report, we present a case of huge extra-adrenal myelolipoma in renal parenchyma which is rare site for its origin. Read More

Presacral Myelolipoma: The Usefulness of a 99mTc-Albumin Nanocolloid Scintigraphy.

Clin Nucl Med 2021 Jan;46(1):38-39

From the Departments of Nuclear Medicine.

Myelolipoma is a rare mesenchymal tumor consisting of adipose tissue and hematopoietic cells. Found usually in the adrenal region, however, few cases have been reported in extra-adrenal regions, most frequently in the presacral region. It is important to recognize such tumor, as it can attain massive size and causes pressure symptoms, and needs to be differentiated from malignant tumors, including liposarcomas. Read More

Department of General Surgery, School of Medicine, University of Puerto Rico Medical Sciences Campus, San Juan, Puerto Rico.

Adrenal incidentalomas are tumors located in the adrenal glands and found on imaging done for purposes not related to adrenal disease. In other cases adrenal mases can be radiologically found when an adrenal hormone secreting tumor is suspected, such as a pheochromocytoma or Cushing's diseases. Adrenal incidentalomas may be classified as functional or non-functional based on whether they produce hormones, such as aldosterone, cortisol, and androgens, or catecholamines. Read More

Background: Mediastinal myelolipoma is extremely rare. It is a benign nonfunctioning tumor composed of hematopoietic tissue and mature fatty tissue. Although computed tomography and magnetic resonance imaging are effective in diagnosing mediastinal myelolipoma, a definitive diagnosis is difficult to establish for rare extra-adrenal myelolipomas by imaging alone.

Baylor College of Medicine, Houston, Texas, USA

Macroscopic fat inside an adrenal lesion on CT is pathognomonic for myelolipoma, a benign neoplasm. Without macroscopic fat, it can be difficult to discern the nature of an indeterminate adrenal mass on imaging. One possible diagnosis for an indeterminate lesion without macroscopic fat is an adrenal oncocytic neoplasm (AON). Read More

Department of Nephrology, Hormozgan University of Medical Sciences, Bandarabbas.

As a rare and normally-benign and functionless tumor, primary adrenal myelolipoma comprises adipose tissue and myeloid cells, and its diagnosis is usually difficult owing to its asymptomatic nature. Imaging techniques can detect these masses in over 90% of the cases. CT scan is the most sensitive imaging technique, which can display the tissue nature of this tumor with a high resolution.

Department of Endocrinology and Metabolism, Ajou University School of Medicine, Suwon, Republic of Korea.

Rationale: Congenital adrenal hyperplasia (CAH) is caused by various enzyme deficiencies, among which 21-hydroxylase (21-OH) deficiency accounts for more than 90% of cases. Neonatal screening became mandatory only a few decades ago. Many patients who were born before this went undiagnosed and some of the severely virilized females were raised as men. Read More
