Abstract：Leiomyoma is a benign tumor originating from mesenchymal tissue,commonly occurring in smooth muscle.Primary intracranial leiomyoma is clinically rare and predominantly affects immunocompromised patients,with immunocompetent individuals being exceptionally uncommon.This article reports a case of a 56-year-old male admitted with a 9-month history of right frontotemporal pain that worsened over the previous month.Preoperative MRI revealed a mass in the right temporal lobe exhibiting isointense signal on T1-weighted imaging and heterogeneous hyperintensity on T2-weighted imaging,with heterogeneous enhancement.The lesion measured approximately 37 mm×25 mm×35 mm and was accompanied by significant peritumoral edema.Chest and abdominal examinations showed no space-occupying lesions,and serological tests were negative for HIV antibodies and hepatitis B surface antigen.Following preoperative preparation,the tumor was microsurgically resected.Intraoperatively,the tumor appeared grayish,adhered to the dura,and displayed a firm consistency with moderate blood supply.It was well-demarcated from the surrounding brain tissue and completely excised.Postoperative pathological diagnosis confirmed a smooth muscle tumor.The patient's headache resolved postoperatively,and he recovered well.No tumor recurrence was observed during the 2-year follow-up period.
