Table 1.

Abscess localisation correlated to primary or secondary origin

Abscess localisation
Primary SEA cervical	4
Primary SEA thoracic	5
Primary SEA lumbar	11
Primary SEA sacral	2
Primary SEA with spondylodiscitis	2
Secondary SEA cervical	1
Secondary SEA thoracic	4
Secondary SEA lumbar	17
Secondary SEA sacral	3
Secondary SEA with spondylodiscitis	3
Total number of abscess lesions	52

The total number of lesions (n = 52) is higher than the number of patients (n = 36) due to SEAs might be located in two or more regions, as well as to the fact that the spondylodiscitis cases are counted twice. This extension is shown in Table 2
