Abstract

Looking at magnetic resonance images of the brain, clinicians as well as neuroradiologists are occasionally confused by dilated perivascular spaces. It has been suggested that dilated perivascular spaces are hallmarks of mild brain injury. To test this conjecture, 530 consecutively examined patients were interviewed by a questionnaire. The data revealed no causal connection between mild traumatic brain injury and dilated perivascular spaces.

Zusammenfassung

Die Magnetresonanztomographie zeigt häufig erweiterte Perivasalräume im Gehirn, was Kliniker wie Neuroradiologen gelegentlich irritiert. Zur Überprüfung der Aussage, erweiterte Perivasalräume seien ein Kennzeichen für ein erlittenes leichtes Schädel-Hirn-Trauma, wurden 530 aufeinanderfolgend untersuchte stationäre Patienten mittels eines Fragebogens befragt. Die Daten zeigen keinen ursächlichen Zusammenhang zwischen einem leichten Schädel-Hirn-Trauma und erweiterten Perivasalräumen.
