Abstract

Transcranial Doppler (TCD) sonography is a new imaging technique allowing for non-invasive evaluation of the intracranial vascular anatomy and cerebral hemodynamics. The recent introduction of echographic contrast agents has significantly increased the sensitivity of TCD for the diagnosis of intracranial vascular lesions. We report a case of giant AComA aneurysm, undetected by color and power TCD, which became visible after echographic contrast administration as a delayed and persistent area of contrast enhancement. Knowledge of atypical or contrast-specific lesion appearances will become important if contrast-enhanced TCD is to be used routinely in the diagnosis of intracranial aneurysms.
