Adrenal myelolipoma is a benign tumour of the adrenal gland.

Myelolipoma redirects here.

General

  • Benign and rare.
  • Typically asymptomatic and hormonally inactive.[1]
    • Symptoms: back or abdominal pain.
  • Diagnosis - usu. by abdominal CT.

Treatment:

  • Watchful waiting if small (<=7 cm) and asymptomatic.[1]

Microscopic

Features:[2]

  • Adipose tissue.
  • Hematopoietic elements from all three lineages:
    1. Erythroid.
    2. Myeloid.
    3. Megakaryocytic.
  • +/-Calcification.[1]

DDx:[3]
