“…The diagnostic yield of this type of procedure varies between 69.6% and 100%. 1,2,[4][5][6][7][8][9][10][11][12]15,[17][18][19][20][21] This wide variation may be explained by several methodological differences. Some articles consider only tumors; 1,2,5,9-11,15,18 others assess only a single, specific site (such as the pineal region) 2,10,13,18 or limit patients to a selected age range (e.g., children).…”

“…2,17,21 According to this last definition, our rate of positive results would be 97.9%; the corresponding value in the literature ranges between 82.6% and 100% (Table 2). 1,2,[4][5][6][7][8][9][10][11][12]15,[17][18][19][20][21] However, if a biopsy is performed to establish a possible treatment, we cannot count a nonspecific histopathological result as positive. Depreitere et al classified the pathological report into 4 categories: Level I, fully diagnostic with no reservations; Level II, diagnostic with some reservations from the pathologist but with strong arguments for the preferred diagnosis; Level III, definitely reflective of abnormal or neoplastic tissues but problematic in coming to definitive diagnosis; and Level IV, not reflective of abnormal tissue or unable to make an interpretation.…”
