- •We present two cases of tumefactive demyelination (TD) occurring in proximity to a DVA.
- •There has only been one previously reported case of this finding in the literature.
- •Venous derangement has been hypothesized to play a role in demyelination.
- •The DVA or its effects on the adjacent tissue may have potentiated the development of TD.
- •Recognizing imaging features of TD may avoid invasive procedures on this “do not touch” lesion.
Abbreviations:TD (tumefactive demyelination), DVA (developmental venous anomaly), AML (acute myelogenous leukemia)
