Resumen
NAVARRO-OLVERA, José L. et al. Stereotactic biopsy for intracranial space occupying lesions: Experience in a referral hospital in Mexico. Cir. cir. [online]. 2021, vol.89, n.6, pp.763-768. Epub 08-Feb-2022. ISSN 2444-054X. https://doi.org/10.24875/ciru.20001009.
Background:
Stereotactic brain biopsy (SBB) is used for establishing the histological diagnosis of intracranial lesions that are not amenable for a direct surgical approach.
Objective:
The objective of the study was to describe our experience having an evaluation of the biopsy sample by a neuropathologist during SBB.
Materials and methods:
Retrospective analysis of 140 consecutive patients who underwent SBB between 2014 and 2018 in whom trans-operatory analysis of the sample was performed.
Results:
There were 56% men. The mean age was 45 years. Histological diagnosis was performed in 131 of 140 patients (94% overall diagnostic yield). The presurgical radiological diagnosis was correct in 39%. Neoplastic lesions were reported in 108 cases, and 32 were non-neoplastic. We performed craniotomy and resection after biopsy in 14%. We found complications in 6% of patients.
Conclusions:
SBB continues to be a safe, useful, and inexpensive procedure. The diagnostic performance of SBB increases when intraoperative cytological evaluation by a neuropathologist is included in the study.
