“…However, we do not believe this to be the case, as MRI has been shown to be 97% sensitive in detecting unruptured AVMs. 9 Our patient's first MRI study was of good quality and was reviewed by neurosurgeons and a pediatric neuroradiologist with knowledge of the subsequent MRI findings. Furthermore, our patient's medical history was clear.…”

Arteriovenous malformations (AVMs) are typically considered congenital lesions, although there is growing evidence for de novo formation of these lesions as well. The authors present the case of an AVM in the same cerebral cortex that had been affected by a severe traumatic brain injury (TBI) more than 6 years earlier. To the best of the authors' knowledge, this is the first report attributing the formation of an AVM directly to TBI.

“…Second, we did not include CTA and MRA for study. Because of the sensitivities and specificity of CTA and MRA for detection of cerebral AVM are only 74-90% and there are some practical limitations in the use of these image modalities in the clinical setting, further evaluation of using these images for target delineation should be done [24]. Third, vascular lesions such as AVM in this study are relatively functional lesions instead of solid soft tissue mass, and functional imaging like angiography should be necessary for diagnosis.…”

Background: Target identification is important for radiosurgery for arteriovenous malformations (AVMs). Targets defined by different imaging modalities may be inconsistent in practice. Objectives: The goal of this study is to review and analyze the consistency between targets defined by different imaging modalities in radiosurgery for AVMs. Methods: From March 2007 to June 2011, AVM patients for radiosurgery whose targets were delineated by angiography/computed tomography (CT)/magnetic resonance imaging (MRI) were reviewed. Spetzler-Martin grades, hemorrhage history, and treatment volumes were checked. Dice similarity coefficients (DSCs) between targets were calculated and analyzed. Results: Twenty-three patients were enrolled. The mean DSCs were between 0.37 and 0.51 for targets by different modalities. There was no significant difference in DSCs regarding Spetzler-Martin grades and hemorrhage history. For CT-delineated target volumes <3 cm³, MRI-delineated target volumes <5 cm³, and angiography-delineated target volumes <2 cm³, the DSCs between the different image modalities were significantly decreased. Conclusions: Consistency between targets delineated using different image modalities was likely to be unsatisfactory and worsen significantly in niduses with volumes <5 cm³. An iterative multimodality approach to confirm the delineated targets of AVMs is suggested to be indispensable for robust treatment in radiosurgery.
