Correlation Of Imaging Features With Meningioma Recurrence

Objective:Analysis the correlation between non-recurrent and recurrent groups meningioma patients’ age, tumor size, tumor occurrence site, the shape of the tumor, edema around the tumor, the tumor density, strengthening and calcification in radiographic. Comprehensive analysis of the application of these methods to evaluate the risk of recurrence in patients before surgery, to develop a comprehensive treatment measures, and to take appropriate preventive and therapeutic tools to improve their prognosis.Methods:Collection2005-2013Guangxi South Stream Hill Hospital neurosurgeon confirmed by surgery and pathology were119cases of meningioma cases. We refer to these cases in accordance with the non-recurrence and recurrence into two groups. The non-recurrent group selected95cases of patients,and recurrent group selected24case of patients. Preoperative patient’s age comparison between the non-recurrence group and recurrence group, tumor size, tumor occurrence site, the shape of the tumor, edema around the tumor, the tumor under imaging density, strengthen the case and calcification imaging features (CT or MRI), to analyze the presence or absence of significant differences.Results:Recurrent tumors located in the cerebral convexity, parasagittal, falx cerebri and skull base accounted for50%(12/24),8.3%(2/24),16.7%(4/24),25%(6/24meningioma initiation and progression and recurrence is a continuous, whole process, affected by many factors. Recurrent tumors located in the cerebral convexity, parasagittal, falx cerebri and skull base accounted for50%(12/24),8.3%(2/24),16.7%(4/24),25%(6/24; non recurrent group were44.2%(42/95),6.3%(6/95),16.9%(16/95),32.6%(31/95), the two groups there were significant differences (P<0.05); tumor recurrence group is round, lobular and mushroom meningioma were respectively54.17%(13/24),29.16%(7/24),16.67%(4/24), non recurrence group was68.4%(65/95),22.1%(21/95),9.5%(9/95), the two groups there were significant differences (P<0.05); recurrent group within the tumor calcification in25%(6/24), higher than that of non recurrence group was3.2%(3/95)(P<0.05); recurrent group induced changes in37.50%(9/24),9.5%higher than the non recurrence group (9/95)(P<0.05); two group of tumor size, there is no dural tail sign, there is no homogeneous enhancement, peritumoral edema degree comparison, no significant difference (P>0.05).; non recurrent group were44.2%(42/95),6.3%(6/95),16.9%(16/95),32.6%(31/95), there was significant difference between two groups (P <0.05); tumor recurrence group is round, lobular and mushroom meningioma were respectively54.17%(13/24),29.16%(7/24),16.67%(4/24), non recurrence group was68.4%(65/95),22.1%(21/95),9.5%(9/95), there was significant difference between two groups (P<0.05); recurrent group within the tumor calcification in25%(6/24), higher than that of non recurrence group was3.2%(3/95)(P<0.05); recurrent group induced changes in37.50%(9/24),9.5%higher than the non recurrence group (9/95)(P<0.05); the two group of tumor size, there is no dural tail sign, there is no homogeneous enhancement, peritumoral edema degree comparison, no significant difference (P>0.05).Conclusions:1、The occurrence、progression and recurrence of meningioma is a process of continuous, systemic, affected by various factors.2、The tests of iconography process can only help diagnose recurrent meningioma in some aspect.
