What is Myelolipoma of adrenal gland?
Myelolipoma is a rare, benign neoplasm that predominantly occurs in the adrenal gland and is composed of mature adipose tissue and scattered islands of hematopoietic elements. Although usually small and asymptomatic, there are some cases of adrenal myelolipoma that cause symptoms such as chronic pain.
What causes Myelolipoma?

Under traumatic situations, direct compression between the spine and the abdominal organs cushioning adrenal glands, such as spleen and liver, could result in hemorrhage by increasing the intravascular pressure or cause vessel rupture directly.
What is a Ganglioneuroma tumor?
Ganglioneuromas are rare tumors that most often start in autonomic nerve cells. Autonomic nerves manage body functions such as blood pressure, heart rate, sweating, bowel and bladder emptying, and digestion. The tumors are usually noncancerous (benign). Ganglioneuromas usually occur in people over 10 years of age.
Are adenomas always benign?
