Title: Imaging diagnosis of tumor-like inflammatory demyelinating diseases
Abstract: Objective
To study the characteristics of tumor-like inflammatory demyelinating diseases and to investigate imaging diagnostic value in tumor-like inflammatory demyelinating diseases further.
Methods
The manifestations of 9 patients with tumor-like inflammatory demyelinating diseases confirmed by pathological assessment and treatment were analyzed retrospectively and relevant literatures were reviewed.
Results
The single localized tumor-like lesions was presented in all 9 cases. CT scan showed low density. MRI showed long T1, T2 signal, and slightly high signal presented on DWI. Open-ring enhancement was observed in 6 cases; closed-ring enhancement in 1 case; nodular or patchy enhancement in 2 cases; mild edema round the lesion with mild space occupying effect. By using glucocorticoids, MRI scan showed lesions was significantly smaller and enhancement was significantly lower, and DWI signal was lower in 6 cases.
Conclusions
Tumor-like inflammatory demyelinating diseases has specific manifestation in MRI and CT. Enhanced MRI and the application of new technology of MRI can clearly show the pathological feature of the disease, which has important value for its diagnosis and differential diagnosis to detect lesions outcome situation.
