“…As observed in our case, AMLs are presented as hyperechoic or hypoechoic images on U/S, depending on the predominance of fatty tissue or bone marrow elements, respectively [8]. On CT scan, they are demonstrated as low-attenuation, well-defined, encapsulated lesions containing fat density along with higher density myeloid elements, as in our case [2,3].…”

Giant adrenal myelolipoma is a rare, benign, sizable, mesenchymal tumor. Preoperative differential diagnosis from retroperitoneal liposarcoma may be challenging. A 66-year-old female patient was admitted because of a sizable tumor at the right retroperitoneal space, incidentally discovered during abdominal ultrasonography for screening purpose. Preoperative imaging studies were indicative for the diagnosis of a giant adrenal myelolipoma (11.7 × 12.9 cm in size); however, a retroperitoneal liposarcoma could not be excluded. We decided to proceed with tumor's surgical removal by using laparoscopic transperitoneal approach and threedimensional high-definition camera. Intraoperatively, the tumor did not infiltrate surrounding tissues and was surrounded by a thin capsule under which there were sparse, orange-colored spots that resembled adrenal cortex. This finding reinforced the initial and most possible diagnosis of adrenal myelolipoma and we easily enucleated the mass. Postoperative course was uneventful, and the patient demonstrated no recurrence on imaging six months postoperatively. Histology confirmed the diagnosis of giant adrenal myelolipoma, measuring 16.5 x 15 x 6.5 cm.

An 8-year-old Scottish terrier was presented with a red and painful right eye. Slitlamp biomicroscopy and ocular ultrasound demonstrated the presence of a large mass in the anterior chamber. Enucleation was performed one week after initial presentation. Histological examination of the eye revealed a relatively well-delineated mass distorting the dorsal iris and occupying most of the anterior chamber. The tumor was composed of fully differentiated adipose tissue and normal hematopoietic cells of the three major blood-forming elements. These findings were most consistent with the diagnosis of an anterior chamber myelolipoma distorting the iris. To the author's knowledge, this is the first report of an intraocular myelolipoma in any species.

“…CT is most sensitive dedication imaging modality for diagnosing them [6]. CT shows fat density (-30 HU to -100 HU) in the adrenal tumor and adrenal myelolipomas are avascular at angiography [2,7]. MRI shows characteristic hyperintense mass due to fat component on T1-weighted and T2-weighted sequences.…”

Multicentric Adrenal Myelolipomas: Case Report

2015

Adrenal myelolipomas are rare and non-functioning benign tumors. They are composed of adipose tissue and hemopoietic elements in varying proportions. In this report we present the case with two myelolipomas at the right adrenal gland that was undefined in the literature. A 40-year-old female patient referred our hospital for overweight. During searching the etiology of obesity, lesions were found incidentally on the abdominal computed tomography (CT) imaging. On the right adrenal gland two well-circumscribed mass lesions were found, and magnetic resonance imaging (MRI) was performed. After intravenous (IV) gadolinium administration no contrast enhancement was seen. Surgical operation was recommended to the patient, but the patient has not accepted yet. In the literature, bilateral adrenal myelolipomas were reported, but multicentric adrenal myelolipomas in the same adrenal gland have not been reported yet. In our case we have shown multicentric adrenal myelolipomas which can be seen in the same adrenal gland. Radiologic imaging keeps the most important place in the diagnosis of lesion and planning of the treatment.
