“…Multiple localisation is possible in 30%-40% of cases [2,16,19], with up to eight disc calcifications having been found in one asymptomatic patient [2] and a median of 1.9 calcifications according to Girodias et al [16] and 1.69 per patient according to Sonnabend et al [8]. Disc calcifications are found with greater frequency in the 6-to 10-year age group [7,8,16,19,20,22,23,25], although some cases have been found during the first hours or days of life [2,11,16]. There is a slight predominance among males (7:5 male-to-female ratio), in whom they more commonly affect the cervical spine, whereas distribution is uneven at the cervical and dorsal spine in females; there is a clear-cut prevalence in Caucasians patients [3,7,8,16,21,23,25].…”
