[Ruptured vascular adrenal cyst after being hit by a wave]

Endothelial cysts of the adrenal gland are a rare entity of adolescents. We here present the case of a 19-year-old woman, who developed right abdominal pain after trauma. Magnetic resonance imaging showed a tumor in the right adrenal gland with suspicious signs for malignancy. Histopathological examination revealed the diagnosis of an endothelial (vascular) adrenal cyst. In most cases, cysts of the adrenal gland remain clinically inapparent. In cases of clinically manifest symptoms, surgical intervention represents the standard for therapy.
