Introduction Primary intracranial angioleiomyoma (ALM) is quite rare and ALM of the adolescent is even rarer. To date, only three cases of adolescents have been reported. Material and methods We carefully introduced a new location of intracranial ALM in an adolescent. The clinical, pathological and imaging features of intracranial ALM were described in detail and published literature was reviewed. Results To our best knowledge, we presented the fourth primary intracranial ALM of adolescent and the first ALM of the right frontal cranial base with intracranial and extracranial communication. We not only summarize the generalities of ALM but also illustrate the difference between adult and adolescent ALM in the aspects of gender and age predominance, etiology, common location and pathologic subtype. Conclusions We reported the first ALM of the right frontal cranial base with intracranial and extracranial communication of an adolescent with a good prognosis. We also summarize the generalities of ALM and illustrate the difference between adult and adolescent ALM. Future investigation of control study with large patient cohorts is needed for both adult and adolescent ALM to compare the difference between them.
