Introduction The management of bAVM involving sensorimotor eloquent areas is challenging and controversial. Patient-centered counseling in high-volume centers is essential.

Aim of Study: patient selection for treatment is an art in the hands of experienced surgeons. A PubMed based search was performed in order to develop a better insight of these challenging lesions.

Methods a scoping review was undertaken. Both traditional database and citation searching were performed. The studies of patients with bAVM involving sensorimotor eloquent areas were screened and summarized narratively.

Results all type of articles, reviews and conference abstracts were included in the scoping review. Word cloud and diagrams summarized the strategical considerations and the decision making process. Structural MR images, fMRI, DTI and angiograms highlight different patterns of this challenging entity. IONM, IOUS and flowmetry can be used. Both curative and adjuvant embolization were reported. Radiosurgery and predictors of failure were reported. Salvage embolization after radiosurgery was reported.

Conclusion close cooperation of INR and NS is essential
