Abstract: Objective To analyze the imaging features and surgical approaches of thalamic gliomas.Methods A retrospective study was performed in 20 patients with thalamic gliomas whom were received microsurgery.We analyzed the clinical data of all patients and draw some clinical experiences.Results Two tumors located lateral of thalamus and were close to the insular cortex,18 tumors located lateral of thalamus posterolateral.The posterior limb of the internal capsule(PLIC),based on T2-weighted magnetic resonance axial sections,was displaced anterolaterally in 16 cases and laterally in 4cases.The transylvian trans-insular approach was used for2 cases,the temporal cortex-lateral ventricle surgical approach was used for 6cases,the temporoparietal or parietal-occipital surgical approach were used for 12 cases.In this series,total resction of the tumor was 14 cases,subtotal 3cases,partial 3cases.Post operative improvement was achieved in 11 cases,stabilization in 5cases,aggravation in 4cases.In addition,tumor recurrence was found in two patients during follow-up.Conclusion Microsurgery is an effective method for treatment of thalamic gliomas.The appropriate surgical approach should be based on their location,growth pattern and the displacement of the PLIC.
