Objective: The aim of the study was to investigate the characteristics of meningiomas, which are quite common tumors, in susceptibility-weighted imaging sequence which is increasingly used in magnetic resonance imaging in daily practice.
Methods: This study included 40 patients with intracranial meningioma between 2011 and 2017. The patients comprised 22 females and 18 males with a mean age of 47.7 years (range, 28-81 years). Magnetic resonance imaging with susceptibility-weighted imaging sequence and computed tomography were performed on all patients. The susceptibility score was calculated for each patient via susceptibility-weighted imaging sequence. Accordingly, less than 1/4 of the mass signal loss 1, 1/4-2/4 signal loss 2, 2/4-3/4 signal loss 3, and 3/4-4/4 signal loss were evaluated as 4 points.
Results: According to the pathologic World Health Organization classification, 21 of the patients (52.5%) had grade 1 (15 transitional, 3 meningothelial, 1 angiomatous, 1 microcystic, 1 psammomatous), 14 (35%) had grade 2 (all atypical), and 5 (12.5%) had grade 3 (all anaplastic) meningioma. Ten patients (25%) had calcificationn within the tumor in computed tomography. The median susceptibility score of the patients was 1. When age, tumor size, susceptibility score, and peripheral edema were compared with pathological grades, age (<0.001) and peripheral edema (0.009) were found to be statistically different.
Conclusions: Although meningiomas have different susceptibility-weighted imaging characteristics, this sequence has the potential to be used routinely in meningioma evaluation in the near future.
