Multimodal imaging for the diagnosis of oligodendroglioma associated with arteriovenous malformation: A case report.

Abstract

Background: The rare co-occurrence of oligodendroglioma and arteriovenous malformation (AVM) in the same intracranial location.

Case summary: In a 61-year-old man presenting with progressive headaches, is described in this case study. Preoperative multimodal imaging techniques (computed tomography, magnetic resonance imaging, magnetic resonance spectroscopy, digital subtraction angiography, and computed tomography angiography) were employed to detect hemorrhage, cystic and solid lesions, and arteriovenous shunting in the right temporal lobe. The patient underwent right temporal craniotomy for lesion removal, and postoperative pathological analysis confirmed the presence of oligodendroglioma (World Health Organization grade II, not otherwise specified) and AVM.

Conclusion: The preoperative utilization of multimodal imaging examination can help clinicians reduce the likelihood of misdiagnosis or oversight of these conditions, and provides important information for subsequent treatment. This case supports the feasibility of craniotomy for the removal of glioma with AVM.
