Volumetric differences between controls (n = 68), patients with left MTS (n = 41) and patients with right MTS (n = 21).

Note the more bilateral distribution of atrophy in patients with left MTS. When the sample of patients with left MTS was randomly reduced to n = 21, all differences observed in the full sample remained highly significant with the exception of the right hippocampus (F = 1.30, p = 0.26).Significant at *pAbbreviations: A, Anterior; CC, corpus callosum; Cen, Central; Hipp, hippocampus; L, Left; MA, Middle Anterior; MP, Middle Posterior; P, Posterior; R, Right; SD, Standard Deviation; THLV, Temporal Horn of Lateral Ventricle.
