Bilateral hyperintense basal ganglia on T1-weighted MR images in acquired hepatocerebral degeneration

Akkiz hepatoserebral dejenerasyonda T1-ağırlıklı MR görüntülerinde bilateral hiperintens bazal ganglion görünümleri

Abstract

Cranial magnetic resonance imaging (MRI) findings in a patient with hepatic dysfunction was reported. The MRI examinations revealed bilateral, symmetric hyperintensity in the globus pallidus and subthalamic nucleus on Tl-weighted images. T2-weighted MR images and computed tomography (CT) examinations were normal. The patient did not have clinical findings of hepatic encephalopathy. Although chronic hepatic dysfunction of the patient was not known, hepatocerebral syndrome was thought with only MRI, and it was confirmed with hepatic biopsy. Even if hepatic dysfunction is not known, MRI findings may be very useful for the diagnosis of hepatocerebral degeneration.

Özet

Hepatik disfonksiyonlu bit olguda kraniyal manyetik rezonans (MR) bulgulart rapor edildi. Tl-agirhkh MR in-celemede globus palliduslarda ve subtalamik nukleuslarda simetrik sinyal artislan izlendi. Hastanin T2-agir-hkh MR ve bilgisayarh tomografi (BT) incelemeleri normaldi. Klinik olarak belirgin hepatik ensefalopatt bulgu¬lart yoktu. Kronik karaciger hastahgi bilinmemesine ragmen yalnizca MR inceleme tie hastada hepatoserebral sendrom du§uniildu ve daha sonra karaciger biyopsi ile dogrulandi. MR inceleme, hastada karaciger fonksi-yon bozuklugu bilinmese bile hepatoserebral dejenerasyon tanismda cokfaydah bir tani yontemidir.
