BACKGROUND Primary central nervous system lymphoma(PCNSL)is a non-Hodgkin lymphoma that originates in the central nervous system(CNS)and is exclusively limited to the CNS.Although most PCNSLs are diffuse large B-cell lymphomas,primary CNS T-cell lymphomas(PCNSTLs)are rare.PCNSTLs typically demonstrate some degree of enhancement on contrast-enhanced magnetic resonance imaging(MRI).To the best of our knowledge,non-enhancing PCNSTL has not been reported previously.CASE SUMMARY A 69-year-old male presented to the neurology department with complaints of mild cognitive impairment and gradual onset of left lower leg weakness over a span of two weeks.Initial MRI showed asymmetric T2-hyperintense lesions within the brain.No enhancement was observed on the contrast-enhanced T1 image.The initial diagnosis was neuro-Behçet’s disease.Despite high-dose steroid therapy,no alterations in the lesions were identified on initial MRI.The patient’s symptoms deteriorated further.An MRI performed one month after the initial scan revealed an increased lesion extent.Subsequently,brain biopsy confirmed the diagnosis of PCNSTL.The patient underwent definitive combined chemoradiotherapy.However,the patient developed bacteremia and died of septic shock approximately three months after diagnosis.CONCLUSION The absence of enhancement in the lesion did not rule out PCNSTL.A biopsy approach is advisable for pathological confirmation. 展开更多

BACKGROUND Arterial perforation has inevitably increased as endovascular treatments have become more common for intracranial large vessel occlusions,and even distal,medium vessel occlusions.A distal,medium vessel has a tortuous course and thinner wall compared to large arteries,making it more susceptible to damage.Here,we review the treatment strategies for arterial perforation during mechanical thrombectomy,and we report the case of a patient treated with gelfoam embolization.CASE SUMMARY A 63-year-old woman presented to the emergency department with sudden neurologic symptoms of right hemiparesis and global aphasia.The initial National Institutes of Health Stroke Scale score was 15.Computed tomography(CT)and CT angiography revealed hyperacute infarction and emergent arterial occlusion of the left middle cerebral artery M2-3 portion.During endovascular mechanical thrombectomy,arterial rupture occurred.The patient’s vital signs were stable,but delayed angiography showed persistent active bleeding.Therefore,selective embolization of the injured artery was performed using gelfoam.Subsequent left vertebral and internal carotid angiography was performed to confirm hemostasis.A localized subarachnoid hemorrhage(SAH)was confirmed on a follow-up CT scan.A repeated CT scan after 12 d showed resolution of the SAH,and rebleeding did not occur.CONCLUSION Rescue embolization with gelfoam could be considered an additional option in distal,medium vessel perforation. 展开更多
