Abstract：ObjectiveTo analyze the diagnosisand treatment of a case of traumatic pericallosal aneurysm （TPA）caused by difuse axonal injury（DAI）.MethodsThe clinical data of a patient with TPA secondary to DAI， admitedtotheDepartmentofNeurosurgeryinApril2O23，wereretrospectivelyanalyzed.Therelevant literaturewere reviewed.ResultsThe TPAwassuccessfully treated with endovascularembolization.No new neurological deficits occurred postoperatively，and thepatient recovered wellduringthe 6-month follow-up.ConclusionsTPA isarare complication of head trauma，accounting for less than 1% ofall intracranial aneurysms，with TPA being evenrarer. Enhancing theunderstandingof TPA iscrucial for clinicians toachieve earlydetection，diagnosis，and treatment.

创伤性颅内动脉瘤（traumatic intracranial aneurysm，TICA）的总体发生率不足所有颅内动脉瘤的 1% ，是颅脑创伤后的少见并发症，而创伤性朕周动脉瘤（traumaticpericallosalaneurysm，TPA）虽约占TICA的 30% ，但因TICA整体发病率极低，故 TPA在临床中仍极为罕见[1-3]。（剩余5399字）
