Prenatal presentation of an adrenocortical tumor

Prenatally identified suprarenal masses are most often found to be adrenal hemorrhage. The most common tumor in this situation is neuroblastoma.

We report the case of a rare adrenocortical tumor found prenatally on ultrasound. While most patients with adrenocortical tumors present with virilizing symptoms, our patient did not have evidence of virilization and was presumed to have neuroblastoma.

Following a period of observation, our patient underwent surgical resection due to tumor growth revealing the unexpected diagnosis.
