Abstract
Fogging effect is a transitory phenomenon of concealed cerebral infarction on computed tomography (CT). This effect is generally noticed within 2-3 weeks from the stroke onset. CT scan is the initial diagnostic imaging tool to demonstrate Ischemic strokes and ruling out/in hemorrhage. They usually demonstrate Hypo density on non-contrast CT scan. Iso-dense infarcts are misleading for radiologists and physicians as they might be interpreted as normal in spite of a clinically suspected stroke. Fogging reported to be seen in about 50% of the ischemic strokes. Knowledge of this effect is crucial to avoid misinterpretation or underestimation of this important finding and my guide further management especially if anticoagulants are being considered.
