An intraventricular meningioma and recurrent astrocytoma collision tumor: a case report and literature review

BACKGROUND: Intracranial meningioma and glioma collision tumors are relatively uncommon and are even more rarely located within the ventricles. CASE PRESENTATION: Here, we report a case of a patient with an intraventricular meningioma and astrocytoma collision tumor. A 39-year-old man previously und...

description BACKGROUND: Intracranial meningioma and glioma collision tumors are relatively uncommon and are even more rarely located within the ventricles. CASE PRESENTATION: Here, we report a case of a patient with an intraventricular meningioma and astrocytoma collision tumor. A 39-year-old man previously underwent excision of an astrocytoma in the triangle area of the lateral ventricle and exhibited good post-surgery recovery. The astrocytoma recurred in situ six years after the surgery, and the case was complicated by a malignant meningioma. The patient recovered well after surgery to treat the recurrence and was administered radiotherapy after discharge. In addition to reporting on this case, we conducted a literature review of collision tumors; based on this review, we propose several hypotheses regarding the formation of collision tumors. CONCLUSIONS: We conclude that a possible cause of the collision tumor formation between the intracranial meningioma and the astrocytoma was the recurrence of an astrocytoma-induced malignancy of the arachnoid cells in the choroid plexus.
