Title: MRI Diagnosis of Neighboring Meningeal Enhanced in Atgpical Brain Abscess
Abstract: Objective Retrospectively analyze the MRI appearance of atypical brain abscess and investigate diagnosis value of neighboring meningeal enhanced of MRI in atypical brain abscess. Materials and Methods The MRI findings of 16 cases with atypical brain abscess proved by operation and pathology .All patients were performed by plain and contrast MRI scanning.Plain CT scan was obtained in 5 cases before operation. Results 12 of 16 brain abscess lesions showed single cavity, 4 cases showes multiple cavity .The diameter of abscess cavity was more than 3cm in 13 cases. On the wall of the brain abscess in 12 cases of routine MRI ,there was a dark belt with isointensity signal. Other 4 cases, the wall of the brain abscess is blur and incontinous . All of 16 cases were rings enhanced, 7 cases showed the wall of abscess were uneven thickness, 5 cases presents irregular forms , 4 cases showed enhanced nodules on the wall of abscess.The abnormal enhancing meningeal neighboring the abcess were showed in all patients. Conclusion To master the MRI appearance of atypical brain abscess,especially the enhancing meningeal neighboring the lesion,is helpful for diagnosis.
