It is thought to be secondary of subchondral infarctions of the central endplates and subsequent disk compression of the infarcted bone, leading to the deformity and arching of endplates. The peripheral portions of the endplates are usually spared because of collateral circulation [1, 2]. ‘‘Fish-mouth’’ vertebrae may be found eventually in abdominal and pelvic radiographs, CT and MRIs. Therefore, they should be recognized. Although present in up to 10% of the patients with sickle cell anemia, those vertebral alterations are non-speciﬁc and were also de- scribed in Gaucher’s disease [3, 4]. Fig. 1.
