Abstract:
Objective To explore the influence of peritumoral edema (PTE) on the tendency of recurrent location and morphological character after total resection using MRI. Methods MRI data was collected from 43 patients with recur-rent brain glioma after total resection from four clinical centers and then the influence of of PTE on recurrence patterns af-ter total resection was retrospectively analyzed based on the T2 weighted image. Results The PTE had a significant influ-ence on the recurrent patterns of brain gliomas after total resection. When PTE was mild, the shapes of recurrent gliomas tended to be focal (6/8) and the recurrent locations tended to be local (5/8). When PTE was severe, the shapes of the recur- rent gliomas tended to be spread(30/35 and the recurrent locations tended to be distant (25/35), followed by marginal (7/35), In addition, the morphological patterns and locations of recurrent gliomas were significantly different among different PTE types (all P<0.001). When PTE was ring shape, the shapes of recurrent gliomas tended to be focal (7/9) and the recur-rent locations tended to be local (6/9), followed by marginal (2/9) and distant (1/9). When PTE was irregular shape, most of recurrent locations tended to be distant (25/34), followed by marginal (7/34) but rarely local (2/34). Conclusions The de-grees and the types of brain glioma PTE can significantly influence the locations and morphological patterns of recurrent gliomas after total resection.
