Description
Summary:Traumatic brain injuries (TBI) are commonly associated with motor vehicle accidents. Neuroimaging plays a crucial role in the initial management of TBIs. We present a case of a TBI related to a motor vehicle accident in an 18-year-old woman. Initial brain imaging revealed significant traumatic injuries and an enhancing mass, without restricted diffusion, in the thalamus favored to be a thalamic glioma. Subsequent imaging revealed resolution of enhancement of the thalamic lesion and reduction in size. On review of the original imaging, it was determined that the thalamic lesion was related to a tear and partial thrombosis of a large thalamic vein resulting in infarction and hemorrhage. •Traumatic brain injury is common among young adults.•Venous structures are prone to injury in traumatic brain injuries.•Venous infarcts and injuries can rarely manifest as mass lesions.
