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.

Infantile refsum disease: case report.

Infantile Refsum disease is a rare inborn error of phytanic acid metabolism. It is inherited in an autosomal recessive manner and frequently causes signs and symptoms in the neonate period. The only source of phytanic acid in humans is exogenous, from diet. We report the MR imaging findings in two cases of infantile Refsum disease and note the MR imaging changes that occurred over time because of further progression of the disease. The initial diagnosis in both patients was made on basis of history, clinical findings, and biochemical studies.
