"Tower vertebra": a new observation in sickle cell disease

Background:
Skeletal abnormalities are common in sickle cell anemia. Ischemia, infarction, and growth disturbance of the thoracic and lumbar vertebral bodies are among the most common abnormalities, and can suggest the diagnosis radiographically.
Design And Patients:
We recently encountered two adult patients in whom vertebrae had grown abnormally in height adjacent to infarcted short vertebrae. We then reviewed the thoracic and lumbar spine radiographs of 54 more adult patients with sickle cell anemia.
Results And Conclusion:
A total of eight patients (14%) displayed infarcted vertebrae with compensatory vertical growth of at least one adjacent vertebrae. These resemble the elongated vertebral bodies associated with other conditions. We can find no prior report of this finding in association with sickle cell anemia.
