Ew. Lang et al., The utility of contrast-enhanced MR-angiography for posterior fossa giant cerebral aneurysm management, NEUROL RES, 20(8), 1998, pp. 705-708
The utility of magnetic resonance angiography is sometimes limited in the d
iagnostic workup of cerebral aneurysms with low flow and/or partial thrombo
sis when weighed against digital subtraction angiography. We present the ca
se of a rare superior cerebellar artery giant, partially thrombosed aneurys
m in which additional i.v. contrast-enhanced MRA sequences were comparable
to digital subtraction angiography. It demonstrated not only the exact spat
ial resolution and correct anatomical relation but also the hemodynamics wh
ich were confirmed by intraoperative Doppler ultrasound. This report suppor
ts the feasibility and utility of i.v. contrast-enhanced MRA for posterior
fossa giant cerebral aneurysm management.
