Contrast-induced encephalopathy following cerebral angiography: A case report.

The present study describes the case of patient with contrast-induced encephalopathy following cerebrovascular angiography, and presents the clinical and imaging features, as well as the treatment and prognosis of this patient. Following digital subtraction angiography, cortical blindness and cognitive dysfunction were the main complaints of the patient. The emergency craniocerebral CT scan revealed hyperdense areas in the bilateral cerebellum, thalamus, sulcus and cistern, and a review of the CT scan 24 h following the procedure revealed that the hyperintense lesions were reduced or resolved in these areas. The patient obtained a good prognosis following treatment anti-inflammatory and intracranial pressure reduction treatment. On the whole, the present study demonstrates that cognitive dysfunction may be a clinical manifestation of contrast-induced encephalopathy. Thus, the earlier diagnosis and earlier treatment are crucial for the prognosis of patients.
