Apart from the known superior endplate depression and Schmorl nodule of L4, the vertebral bodies have normal height and alignment. There is diffuse bone marrow signal abnormalities characterised by low T1 and T2 signal and patchy punctate foci of enhancement that are suggestive for bone-marrow infiltration by leukemic cells. A more prominent nodular enhancement within the superior endplate of L4 seems to be also disease related rather than an acute Schmorl nodule. The spinal canal and intervertebral foramina are capacious, with no areas of high-grade stenosis. The cord has normal morphology and signal intensity, with no abnormal enhancement. Paravertebral soft tissues are unremarkable.
