What disease is “hands and feet” syndrome associated with?
Sickle cell anemia - pain and swelling in hands and feet
What complications are associated with sickle cell anemia?
Infarct of bowel following obstruction of mesenteric arteries (abdominal crisis)
What are osseous changes related to sickle cell anemia?
Infarction, avascular necrosis, marrow hyperplasia and retarded growth (short leg/bone)
What does sickle cell anemia predispose one to?
Salmonella osteomyelitis
What are some radiographic signs of sickle cell anemia?
- Marrow hyperplasia - increase in marrow space to make more RBCs
- Coarse trabeculation
- Osteopenia
- Long bone undertubulation (Erlen-meyer last deformity)
- Hair-on-end skull (more prevalent in thalassemia)
- Osteonecrosis/infarct - Lincoln log/H shaped vertebra
