Rare giant primary intracranial angioleiomyoma in lateral ventricle: a case report and the literature review.

Angioleiomyomas are benign tumors and can occur in subcutaneous tissues all over the body, and lower extremities are more common. Primary intracranial angioleiomyomas are rare. We present a case of intracranial angioleiomyoma and review the literature. A 35-year-old Chinese women presented with one-year history of the left leg claudication. MRI revealed a 6.3 × 7.4 × 5.4 cm lesion located in the lateral ventricle, which, to our knowledge is the first lateral ventricle ALM reported. The tumor was resected. The pathological results were consistent with angioleiomyoma. Hemiplegia of left limb was found during post-operative period and no recurrence was found during five month of follow-up. ALM is a rare intracranial tumor but can occur.
