Then, in 2015, a brain and spine MRI exam revealed the presence of a subcentimetric Hb on the right lateral medulla, without associated cyst; two more lesions were detected at C3–C4 and C6, without associated cysts; as well as a nodular Hb at the posterior conus medullaris, with associated edema and thickening of the cone. This evidence concerns the gene GSTM1 and cyst.
