Development of multiple adrenal myelolipomas after trauma-induced adrenal haemorrhage

Abstract

Adrenal myelolipomas represent a benign neoplasm with known associations with many chronic diseases, 21-hydroxylase deficiency and cancer. However, the aetiology of adrenal myelolipomas remains unknown. Here, we present a case of a patient with image-proven bilateral adrenal haemorrhages caused by trauma with the subsequent development of bilateral adrenal myelolipomas several years later. Resection and pathological analysis of left adrenal gland confirmed the presence of multiple adrenal myelolipomas. Our case strongly suggests that trauma was the inciting event that led to the formation of these lesions.
