Hi everyone, I'm having some trouble finding information online about what can cause a "small focus of T2 hyperintensity". An MRI was ordered due to my symptoms of virtigo and tingling in my right arm. What is a developmental venuous abnormality? What causes a small focus of T2 hyperintensity?? Any help you can offer is appreciated!
"The ventricles reveal normal size, shape, and contour. On the sagittal FLAIR sequence, there is a small focus of T2 FLAIR hyperintensity within the left periatrial white matter (series 13 image 18). This corresponds to a small benign developmental venous anomaly on the postcontrast imaging. The brainstem, cerebellum, and cerebral hemispheres otherwise appear unremarkable. There is no evidence of acute intracranial hemorrhage, edema, or hydrocephalus. No mass effect or midline shift is seen. There is no abnormal diffusion restriction to suggest acute infarction. There is no abnormal parenchymal or meningeal enhancement. The visualized skull base and calvarium appear unremarkable."
