Hemangioma of the Adrenal

Minimally invasive adrenalectomy for incidentally discovered cavernous hemangioma

“…Also, at US imaging, this neoplasm has specific features such as well-circumscribed mass with heterogeneous echogenicity and diffused irregular anechoic areas with hyperechoic septa (10,11). Moreover, non-contrast-enhanced CT scan shows a well defined, hypo-attenuated mass sometimes with some calcifications, whereas a characteristic peripheral patchy enhancement and a highly dense peripheral rim are shown at contrast-enhanced CT (1,9,10,12,13). Besides, magnetic resonance imaging shows low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and contrast-enhanced MRI demonstrates delayed centripetal enhancement (6,9,11).…”

“…To the contrary, Yamada et al published a case that showed only a thin rim without centripetal enhancement (12). The most typical, and therefore crucial, CT and MRI features of hemangiomas are calcifications, phleboliths and enhancement of peripheral vascular lakes, corresponding to the pathologic findings (1,6,7,9). Because ultrasonography is helpful for locating the mass but has little ability in displaying calcifications and phleboliths, CT scan or MRI are always necessary to define the nature of the adrenal neoplasms.…”

“…Adrenal gland localization is extremely rare and the first case was described in 1955 (1); since then about 50 cases have been reported in the literature (2). Adrenal hemangiomas mostly affect people between the ages of 60 and 70 years, have a predilection for women and range in size from 2.5 to 25 cm (3,4).…”

Giant Cavernous Hemangioma of the Adrenal Gland: Case Report and Review of the Literature

“…Histologically, these tumors are characterized by the presence of blood-filled, dilated vascular spaces lined with mature endothelial cells. First report was published in 1955 by Johnson and Jeppesen [5]. Performing a literature review, using Embase and Medline, we have found 63 documented cases of adrenal cavernous hemangioma in English literature [6][7][8][9][10].…”

CT and MR Imaging of Adrenal Hemangioma

“…Since the first case of a surgically treated adrenal hemangioma (6), only 27 cases have been reported (2)(3)(4)(5)(6)(7)(8). Previous reports have discussed radiographic findings on abdominal radiography, CT, and angiography.…”
