Leiomyomas, benign tumors of well-differentiated smooth muscle and vascular collagenous tissue, usually occur in the uterus but can develop wherever smooth muscle is present. Primary intracranial leiomyomas are rare tumors. We present the case of a 40-year-old woman with a primary intraventricular leiomyoma. She consulted us for headache, dizziness, and black spots in her vision. Magnetic resonance images (MRI) disclosed a mass rooted in the posterior septum pellucidum. The tumor was totally excised by the senior author with no residual seen on intraoperative MRI. Pathological examination showed it to be a benign spindle-cell neoplasm. On the 6th month control MRI, there was no recurrence. We also reviewed articles relevant to primary intracranial leiomyomas.

平滑肌和良性肿瘤是平滑肌和血管胶原组织的良性肿瘤，通常发生在子宫内，但可以在存在平滑肌的任何地方发展。原发性颅内平滑肌瘤是罕见的肿瘤。我们介绍了一名40岁女性患有原发性脑室内平滑肌瘤的病例。她向我们咨询了视力中的头痛，头晕和黑斑。磁共振成像（MRI）显示肿块根植于透明后隔膜中。该肿瘤由高级作者完全切除，术中MRI未见残留。病理检查表明它是良性梭形细胞瘤。在第6个月的对照MRI上，没有复发。我们还审查了与原发性颅内平滑肌瘤相关的文章。
