Editorial comment on “A new method for quantification and 3D visualization of brain tumor adhesion using slip interface imaging in patients with meningiomas”

Excerpt

Meningioma is the most common primary central nervous system neoplasm, corresponding to 37% of all intracranial tumours [1]. It can be treated effectively by surgical resection or, in selected cases, by radiotherapy [2]. Histological grade and extent of resection are the most important prognostic markers. However, in the last 2016 WHO classification, histopathological evidence of brain infiltration has been integrated as a marker for atypical meningioma, with an impact on prognosis [3]. Even so, some authors remark that histopathological assessment could be biased, as invasive margins may not be surgically resected, therefore impeding histopathological detection [4]. It is also well known that brain invasion or adhesion complicates surgical dissection and increases the risk of stroke, haemorrhage, and other injuries [5]. To summarize, meningioma-brain adhesion assessment could be an “Achilles’ tendon” for meningioma prognostic stratification as well as an important factor for accurate surgical planning, treatment decision, and follow-up strategy. …
