    An uncommon cause of multiple pulmonary nodules; hereditary hemorrhagic telangiectasia
    (Turkish Assoc Tuberculosis & Thorax, 2016) Kosar, Sule; Kizildag, Betul; Canan, Arzu; Karatag, Ozan; Gonlugur, Ugur; Sariyildirim, Abdullah
    Hereditary hemorrhagic telangiectasia ( HHT), or Rendu-Osler-Weber syndrome ( ROWS) is a very rare hereditary disease. The diagnosis is based on the clinical findings such as recurrent epistaxis, telangiectases, visceral arteriovenous malformations (AVMs) and family history. AVMs are found in the liver, lung or brain and could mimick the masses of these organs. Radiologic evaluation plays a critical role during diagnostic and therapeutic management of ROWS. Hence, radiologists should be aware of the diagnosis of HHT in the patients with AVMs, history of epistaxis and family history. We report a patient with multiple pulmonary AVMs secondary to HHT who has referred to our interventional radiology department for computed tomography guided transthorasic lung biopsy procedure with suspicious of malignancy.

    Association between apparent diffusion coefficient and intervertebral disc degeneration in patients with ankylosing spondylitis
    (E-Century Publishing Corp, 2015) Resorlu, Mustafa; Gokmen, Ferhat; Resorlu, Hatice; Adam, Gurhan; Akbal, Ayla; Cevizci, Sibel; Sariyildirim, Abdullah
    Purpose: To assess the relation between ankylosing spondylitis (AS) and degenerative disc disease emerging in association with various intrinsic and extrinsic factors and to evaluate the correlation between degree of degeneration in intervertebral discs and apparent diffusion coefficient (ADC) values. Methods: Thirty-five patients with AS and a control group of 35 patients were included in the study. Three hundred fifty intervertebral discs were assessed in terms of degeneration by analyzing signal intensities and morphologies on T2 weighted series of a 1.5 Tesla magnetic resonance scanner. ADC values were determined in diffusion weighted images (DWI) using a b value of 500 s/mm(2). Patients in the AS and control groups were compared in terms of intervertebral disc degeneration, and association between degree of degeneration and ADC values was analyzed. Results: The mean of total degeneration degrees for five lumbar intervertebral discs was significantly higher in the patients with AS compared to the control group (16.77 +/- 4.67 vs 13.00 +/- 4.08, respectively; P=0.001). When intervertebral discs were analyzed separately, disc degeneration was again significantly higher in patients with AS compared to the control group, with the exception of L5-S1. Age, cholesterol level, triglyceride level, duration of disease and BASFI index were significantly associated with degree of degeneration in patients with AS. A negative correlation was determined between disc degeneration and ADC value. Conclusion: AS is a risk factor for degenerative disc disease due to its systemic effects, the fact it leads to posture impairment and its inflammatory effects on the vertebrae. A decrease in ADC values is observed as degeneration worsens in degenerative disc disease.

    Association of Congenital Left Renal Vein Anomalies and Unexplained Hematuria: Multidetector Computed Tomography Findings
    (Karger, 2015) Resorlu, Mustafa; Sariyildirim, Abdullah; Resorlu, Berkan; Sancak, Eyup Burak; Uysal, Fatma; Adam, Gurhan; Akbas, Alpaslan
    Objectives: To investigate whether congenital renal vein anomalies are involved in the etiology of hematuria by analyzing abdominal multidetector computed tomography (MDCT) results. Methods: Six hundred and eighty patients undergoing MDCT for various abdominal pathologies in whom possible causes of hematuria were excluded were retrospectively assessed in terms of left renal vein anomalies, such as circumaortic left renal vein (CLRV), retroaortic left renal vein (RLRV) and multiple renal vein (MRV). Patients with CLRV, RLRV or MRV and patients with normal left renal veins were compared in terms of the presence of hematuria. Results: Left renal vein anomalies were detected in 100 patients (14.7%). RLRV, CLRV and MRV were identified in 5.4, 2.5 and 6.8% of patients, respectively. Hematuria was determined in 8.1% of patients with an RLRV anomaly and in 10.5% of patients with no RLRV anomaly (p = 0.633). Hematuria was detected in 23.5% of patients with a CLRV anomaly and 10.1% of those without (p = 0.074), and in 21.7% of patients with an MRV anomaly and 9.6% of those without (p = 0.009). Condusions: In addition to increasing risk of complication during retroperitoneal surgery, numeric congenital renal vein anomalies are also significant in terms of leading to clinical symptoms such as hennaturia.

    Ergotamine-induced vasospastic ischemia mimicking arterial embolism: unusual case
    (Turkish Assoc Trauma Emergency Surgery, 2014) Adam, Gurhan; Kurt, Tolga; Cinar, Celal; Sariyildirim, Abdullah; Resorlu, Mustafa; Uysal, Fatma; Yener, Ali Umit
    Ergotamine toxicity is an important and rare condition, including tachycardia, arterial spasm which occurring as a result of accidental overdosing or drug interactions. We assessed the consequences of delayed diagnosis of peripheral arterial vasoconstriction occurring after simultaneous macrolide use by a 35-year-old woman using an ergot-derived drug for migraine. Diagnosis of ergotamine intoxication begins with suspicion. Interventional radiologists and surgeons should be aware of this acute dangerous condition.
