Reversible hyperintense lesion after balloon occlusion test.
We report a unique case of a reversible high signal intensity lesion observed on a magnetic resonance (MR) image accompanied by transient neurological deficits related to a balloon occlusion test. This abnormality was considered to be vasogenic edema caused by the disruption of the blood-brain barrier (BBB) due to a long history of uncontrolled hypertension and transient ischemia induced by the balloon occlusion test.
