Peripheral nodular enhancement in adrenal and renal hematomas: A report of 3 cases

“…PEH, also known as Masson's tumor, is a reactive process seen in stages of organization and recanalization of a hematoma/hemangioma or any vascular malformation [7] . PEH is benign and is most frequently seen in the skin and integument of the head, neck, and extremities, but may involve any of the visceral organs [8] , [9] , [10] , [11] , [12] , [13] .
