ABSTRACT
@#To Invetigate chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids （CLIPPERS）clinical diagnosis、the imaging manifestations and the course of treatment to raise the awareness of the disease. Methods To retrospectively analyse clinical diagnosis、the imaging manifestations and the course of treatment of 2 patients with CLIPPERS. Results One patient’s Brain MRI having long T1 and slightly longer T2 signal，not significantly high signal in the DWI，in the brain stem、basal ganglia and cerebellar hemisphere. Another patient had long T1 and slightly longer T2 signal，not significantly high signal in the DWI，in the brain stem and cerebellar hemisphere. Two patients’brain MRI with gadolinium foci of enhancement with a curvilinear pattern highly. Theirs’ magnetic resonance vascular examination were normal. Theirs’symptoms and imagings had improving significantly after glucocorticosteroid shocking treatment. One patient relapsed with long-term oral prednisone，after the second glucocorticosteroid shocking，with long-term oral prednisone and glucocorticosteroids，he had obviously improvement. So far，the patient only uses oral azathioprine，he is well. Another patient died of pneumonia for a week after leaving hospital. Conclusion CLIPPERS syndrome has obviously imaging findings on MRI，and having to get better after glucocorticosteroid treating，prompting CLIPPERS syndrome may be a syndrome of heterogeneous etiology，not an independent disease.
