“…[ 2 , 4 , 6 ] In particular, vascular disease in this area, for example, DAVF, is even more difficult to diagnose accurately, and appropriate therapeutic interventions often tend to be delayed. [ 1 , 2 , 8 , 10 ] Thus, we should take utmost care when treating pathological lesions in this part.…”

“…On the other hand, it is so far uncommon and probably unknown that the edematous lesion caused by venous congestion with an intracranial DAVF can produce a similar radiological pattern to that of malignant glioma, especially Gd contrast enhancement and spinal cord enlargement. [ 1 , 2 , 6 , 8 , 10 ] In the case of a DAVF in the posterior cranial fossa, the venous drainage is through a unique cisternal arterialized vein, leading to venous congestion. This congestion occurs due to the increasing venous pressure, responsible for slowing drainage of the venous routes of the brain, and spinal cord.…”

Background: The findings of a hyperintense sign on T2-weighted imaging (T2-WI) and gadolinium (Gd) contrast enhancement on magnetic resonance imaging (MRI) of the brain stem suggest malignant glioma. However, this pathological condition is probably uncommon, and it may be unknown that a dural arteriovenous fistula (DAVF) can imitate this radiological pattern. In addition, it is extremely rare to be caused by a spinal DAVF. Here, a rare case of spinal DAVF that mimicked malignant glioma of the medulla oblongata is presented. Case Description: A 56-year-old woman was admitted with a progressive gait disturbance, vertigo, and dysphasia. MRI showed a hyperintense signal in the medulla oblongata on fluid-attenuated inversion recovery (FLAIR) and moderate contrast enhancement on Gd-enhanced MRI. Interestingly, Gd-enhanced MRI demonstrated abnormal dilated veins around the brain stem and cervical spinal cord. Cerebral angiography showed spinal DAVF at the left C4/C5 vertebral foramen fed by the C5 radicular artery. The fistula drained into spinal perimedullary veins and flowed out retrograde at the cortical vein of the posterior cranial fossa. Therefore, surgical disconnection of the spinal DAVF was performed by a posterior approach. The patient’s postoperative course was uneventful. Cerebral angiography showed complete disappearance of the DAVF, with marked reductions of the hyperintense sign of the medulla oblongata on FLAIR. Conclusion: This important case illustrates MRI findings mimicking brain stem glioma. In cases with the hyperintense sign-on T2-WI associated with contrast enhancement suspicious of brainstem glioma, careful checking for perimedullary abnormal vessels and additional cerebral angiography should be performed.
