Abstract：ObjectiveTo discussion clinical manifestation and the imaging characteristics of atypical brain stem cavernosum malformation.MethodsThe clinical and imaging data of one patient with brain stem cavernous malformation who was confirmed by pathology were analyzed,and related literatures were reviewed.ResultsLeft limb weakness,headache were the first symptoms.The patient felt the left side of the body was slightly weak and the left foot thumb flexion was difficult.Brain magnetic resonance imaging (MRI) scan showed:the brain has cystic lesions;MRI enhanced scan showed that the lesions assumed ring enhanced,slightly thick wall,slightly blurred ring.MRI spectrum analysis showed that NAA peak increased,CHO peak decreased,which was considered glioma.Under the simulator positioning local radiotherapy was given for 15 times in a row.Temozolomide chemotherapy was given at the same time.Limb weakness and headache symptoms were not significantly reduced after treatment,while symptoms aggravated,and the patient could not take care of himself when discharged from the hospital.The course lasted nearly 1 year,the main clinical symptom was headache,postoperative pathology was brain stem cavernous.ConclusionsThrough the analysis of the case,brain stem cavernous malformation can show cystic change,and can be showed ring enhancement in enhanced scan.It should distinguish from brain stem glioma.
