Transient neurologic deficit after acetazolamide challenge for computed tomography perfusion imaging.
A case of transient neurologic deficit associated with the acetazolamide challenge conducted in conjunction with dynamic enhanced computed tomography (CT) perfusion imaging for the evaluation of cerebral hemodynamic impairment is reported in a patient with known cerebrovascular steno-occlusive disease. Combining the acetazolamide challenge with dynamic CT perfusion provides a rapid and widely available technique to assess cerebrovascular reactivity; however, one must be cognizant of this serious potential adverse response.
