A Rare Presentation of Lisegang Rings in Adrenal Cavernous Hemangioma : Case Report and Literature Review.

Background: Adrenal cavernous hemangiomas (AH) are benign nonfunctional vascular tumors rarely discovered as incidental findings on imaging studies or autopsies. This study presents a single case report of AH with another rare finding of the Liesegang ring. Also, we reviewed 73 case reports of cavernous adrenal hemangioma to provide an overview of AH's clinical characteristics.
