Magnetic resonance imaging (MRI) is the most widely discussed and clinically employed method for the differential diagnosis of oligodendrogliomas; however, MRI occasionally produces unclear results that can hinder a definitive oligodendroglioma diagnosis. The present study describes the case of a 34-year-old man that suffered from headache and right upper-extremity weakness for 2 months. Based on the presurgical evaluation, it was suggested that the patient had a World Health Organization (WHO) grade II-II glioma, meningioma or arteriovenous malformation (AVM), with unclear radiological manifestations. Postsurgical pathological assessment confirmed the tumor to be an anaplastic oligodendroglioma (WHO grade III). This case is notable due to the confusing radiological manifestation of a mushroom-shaped anaplastic oligodendroglioma in the parietal-temporal-occipital region, which provided a potential source of misdiagnosis for meningioma and AVM.
