    Digital subtraction angiography of a persistent trigeminal artery variant
    (Aves, 2010) Temizoz, Osman; Genchellac, Hakan; Unlu, Ercuement; Cagli, Bekir; Ozdemir, Hueseyin; Demir, M. Kemal
    Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is very rare. We present this uncommon anomalous artery along with digital subtraction angiography findings and discuss its clinical significance in light of the literature.

    Hepatic Encephalopathy and Atypical Cortical Involvement in Cranial MRI: case report
    (Aves Yayincilik, Ibrahim Kara, 2009) Celik, Yahya; Ozbek, Bahar; Balci, Kemal; Unlu, Ercuement; Utku, Ufuk
    Hepatic encephalopathy is characterized by neuropsychiatric abnormalities occurring in patients with liver dysfunction. It most commonly occurs in association with cirrhosis, portal hypertension, portal-systemic shunts and acute liver failure. Clinical features of hepatic encephalopathy varies between mild cognitive impairment to deep coma. Several neuroimaging techniques, especially magnetic resonance imaging (MRI), may eventually be useful for the diagnosis of hepatic encephalopathy. Cranial MRI may demonstrate high signal intensity in the bilateral globus pallidum on T1-weighted images. Cortical involvement due to hepatic encephalopathy is rarely reported in the literature. We presented here a case of hepatic encephalopathy with cortical and subcortical involvement.

    Hypothenar hammer syndrome
    (John Wiley & Sons Inc, 2008) Genchellac, Hakan; Demir, Mustafa Kemal; Unlu, Ercuement; Temizoz, Osman; Ozdemir, Huseyin
    We report a case of hypothenar hammer syndrome following a single severe blunt trauma in a 24-year-old man with a painful pulsatile mass, numbness in the fourth and fifth fingers, and intolerance to cold. The gray-scale and color Doppler sonographic findings are presented with correlation with MRI. (C) 2007 Wiley Periodicals, Inc.

    Postural tremor as a manifestation of spontaneous intracranial hypotension
    (Elsevier Sci Ltd, 2010) Turgut, Nilda; Unlu, Ercuement; Hamamcioglu, Mustafa Kemal; Guldiken, Babuerhan; Albayram, Sait
    Spontaneous intracranial hypotension (SIH) is a syndrome caused by low cerebrospinal fluid (CSF) pressure due to leakage of CSF. Clinically, orthostatic headache, neck pain, nausea, emesis, interscapular pain, diplopia, dizziness, changes in hearing, visual blurring and radicular upper extremity symptoms are most frequently observed. We describe a 57-year-old man with SIH who presented with postural tremor. CSF leakage was revealed by cranial MRI. Lumbar puncture identified low CSF pressure and intrathecal gadolinium enhanced MR cisternography showed diffuse CSF leakage in the thoracolumbar region. The patient underwent epidural blood patching, which resulted in complete resolution of postural tremor within 2 months. (C) 2009 Elsevier Ltd. All rights reserved.
