Sonographic appearance of myelolipoma: Demonstration of adrenal and pelvic lesions

Sonographic appearance of myelolipoma: Demonstration of adrenal and pelvic lesions Edward 1. Miller, MD and Russell W.

With the advent of ultrasound and computed tomography (CT), tumor is being more frequently recogthe nized preoperatively. The imaging characteristics of marked hyperechogenicity on ultrasound examination and fat density on CT allow a presumptive preoperative diagnosis in the adrenal gland area, where the mass is usually located.

Abstract

Edward 1. Miller, MD and Russell W. Dickerson, MD Myelolipoma is an uncommon tumor composed of varying amounts of fat and bone marrow elements. Most cases reported until recently were discovered incidentally at autopsy. With the advent of ultrasound and computed tomography (CT), tumor is being more frequently recogthe nized preoperatively. The imaging characteristics of marked hyperechogenicity on ultrasound examination and fat density on CT allow a presumptive preoperative diagnosis in the adrenal gland area, where the mass is usually located. Very rarely, myelolipoma may appear in the pelvis, where it may appear similar on ultrasound to a solid gynecological mass or pelvic sarcoma. Two patients, one with adrenal myelolipoma, the other with presacral myelolipoma are presented. CASE REPORTS Case 1 was removed. The mass was composed of uniform adipose tissue cells throughout which were small islands of normal hematopoietic tissue. The diagnosis was myelolipoma. Case 2 A 79-yr-old woman was admitted to Hoag Memorial Hospital after physical examination had revealed a pelvic mass. Ultrasound examination (Fig 3) revealed a large solid mass occupying the pelvis and markedly compressing the bladder. A sarcoma was considered likely, with ovarian fibroma or Brenner's tumor included in the differential diagnosis. A
