Abstract
Cerebral computed tomography [CT] with and without iodinated contrast, revealed the appearance and evolution of lesions in a 32-yr-old man with multiple sclerosis. Two areas were enhanced with contrast, with 1 showing a mild mass effect and rim of enhancement. Serial brain scintigraphy using 99mTc glucoheptonate, following the [CT], showed the appearance and regression of corresponding regions of increased uptake. [CT] 1 day prior to brain scintigraphy failed to demonstrate a region of increased accumulation of radiotracer. One week later evidence of a corresponding unenhanced defect was noted on CT. Clinical correlation is given additionally.
