    MRI findings in thoracic outlet syndrome
    (2012-11-01) Aralasmak, AYŞE; ÇEVİKOL, CAN; KARAALİ, KAMİL; Senol, Utku; Sharifov, RASUL; KILICARSLAN, Rukiye; Alkan, ALPAY; ARALAŞMAK, AYŞE; SHARIFOV, RASUL; ALKAN, ALPAY
    We discuss MRI findings in patients with thoracic outlet syndrome (TOS). A total of 100 neurovascular bundles were evaluated in the interscalene triangle (IS), costoclavicular (CC), and retropectoralis minor (RPM) spaces. To exclude neurogenic abnormality, MRIs of the cervical spine and brachial plexus (BPL) were obtained in neutral. To exclude compression on neurovascular bundles, sagittal T1W images were obtained vertical to the longitudinal axis of BPL from spinal cord to the medial part of the humerus, in abduction and neutral. To exclude vascular TOS, MR angiography (MRA) and venography (MRV) of the subclavian artery (SA) and vein (SV) in abduction were obtained. If there is compression on the vessels, MRA and MRV of the subclavian vessels were repeated in neutral. Seventy-one neurovascular bundles were found to be abnormal: 16 arterial-venous-neurogenic, 20 neurogenic, 1 arterial, 15 venous, 8 arterial-venous, 3 arterial-neurogenic, and 8 venous-neurogenic TOS. Overall, neurogenic TOS was noted in 69%, venous TOS in 66%, and arterial TOS in 39%. The neurovascular bundle was most commonly compressed in the CC, mostly secondary to position, and very rarely compressed in the RPM. The cause of TOS was congenital bone variations in 36%, congenital fibromuscular anomalies in 11%, and position in 53%. In 5%, there was unilateral brachial plexitis in addition to compression of the neurovascular bundle. Severe cervical spondylosis was noted in 14%, contributing to TOS symptoms. For evaluation of patients with TOS, visualization of the brachial plexus and cervical spine and dynamic evaluation of neurovascular bundles in the cervicothoracobrachial region are mandatory.

    CT Angiography Evaluation of Unusual Transorbital Penetrating Injury: A Toothbrush
    (2013-04-01) ATAY, Musa; Alkan, ALPAY; HANIMOGLU, Hakan; Sharifov, RASUL; KILICARSLAN, Rukiye; Aralasmak, AYŞE; ALKAN, ALPAY; SHARIFOV, RASUL; ARALAŞMAK, AYŞE
    Orbital penetrating injuries may cause significant harm to optic nerves and eyeball as well as to the brain and cerebral vasculature. Defining surrounding neurovascular structures by CT angiography (CTA) is important for surgical removal. We present an uncommon case of a 3-year-old child with a penetrating orbital injury caused by a toothbrush. To the best of our knowledge, there is no report orbital injury with a toothbrush so far.

    Auditory Pathway Features Determined by DTI in Subjects with Unilateral Acoustic Neuroma
    (2016-12-01) KURTCAN, SERPİL; Alkan, ALPAY; Kilicarslan, R.; BAKAN, A. A.; TOPRAK, HÜSEYİN; ARALASMAK, AYŞE; AKSOY, FEYZA MÜBERRA; Kocer, A.; KURTCAN, SERPİL; ALKAN, ALPAY; TOPRAK, HÜSEYİN; ARALAŞMAK, AYŞE
    In the studies concerning the pathology of the auditory pathway in the vestibulocochlear system, few use advanced neuroimaging applications of magnetic resonance imaging (MRI) such as diffusion tensor imaging (DTI). Those who did use reported DTI changes only at the lateral lemniscus and inferior colliculus level. The aim of our study was to determine diffusion changes in the bilateral auditory pathways of subjects with unilateral acoustic neuroma (AN) and compare them with healthy controls.
