    Acoustic Radiation Force Impulse (ARFI) imaging for the distinction between benign and malignant thyroid nodules
    (Springer-Verlag Italia Srl, 2015) Hamidi, Cihad; Goya, Cemil; Hattapoglu, Salih; Uslukaya, Omer; Teke, Memik; Durmaz, Mehmet Sedat; Yavuz, Mehmet Siddik
    The aim of the present study was to evaluate thyroid nodules using virtual touch quantification (VTQ) of force impulse acoustic radiation (ARFI) imaging and to investigate a cutoff value for the differentiation of malignant thyroid nodules. Ninety-five patients with quantitatively-assessed (VTQ) thyroid nodules were evaluated with ARFI imaging in this prospective study. ARFI imaging with VTQ was performed only on the nodules which were expected to undergo fine-needle aspiration biopsy (FNAB). All of the thyroid lesions were examined histopathologically. The mean shear wave velocity (SWV) value of the malignant nodules (3.18 +/- A 0.39 m/s) was higher than that of the benign nodules (2.11 +/- A 0.53 m/s). There was a statistically significant difference between the mean SWV values of benign and malignant nodules (p < 0.001). A SWV cutoff value of greater than 2.66 m/s yielded sensitivity and specificity values of 100 and 82.3 %, respectively, for diagnosis of malignant nodules. VTQ of ARFI imaging has high sensitivity and specificity for discriminating between benign and malignant thyroid nodules and may positively contribute to clinical evaluation of these nodules.

    Bilateral cleft foot: Radiographic and prenatal ultrasound features of two siblings with a review of literature
    (Elsevier Urban & Partner Sp Z O O, 2016) Durmaz, Mehmet Sedat; Demirtas, Hakan; Hattapoglu, Salih; Kara, Taylan; Goya, Cemil; Adin, Mehmet Emin
    Cleft foot deformity, also known as ectrodactyly, is a rare congenital developmental defect of extremities caused by malformation in continuity of apical ectoderm. The syndrome typically involves malformation or absence of the central rays of the feet and is characterized by deformities like median deep clefts of distal extremities. Routine examination of feet during second-trimester ultrasound (US) may increase the detection rates of foot malformations. Many malformations can be diagnosed with 2-dimensional (2D) US, but 3-dimensional (3D) US also helps better understanding of the foot malformations. In the present study, we report the case of two brothers (a fetus and a 5-year-old) with cleft foot deformity. 2D and 3D second trimester US findings of one case and the foot radiography findings of the other are presented here.

    Evaluation of Parathyroid Lesions With Point Shear Wave Elastography
    (Amer Inst Ultrasound Medicine, 2016) Hattapoglu, Salih; Goya, Cemil; Hamidi, Cihad; Tasdemir, Bekir; Alan, Bircan; Durmaz, Mehmet Sedat; Teke, Memik
    Objectives-The aim of our study was to evaluate the shear wave velocity (SWV) of parathyroid lesions by point shear wave elastography (SWE) and to compare their stiffness with that of thyroid nodules and normal thyroid parenchyma quantitatively. Methods-Thirty-six patients considered to have parathyroid disorders by clinical and laboratory tests and scintigraphy were enrolled in the study between January 2012 and February 2015. Conventional sonography, Doppler sonography, and the Virtual Touch tissue quantification (VTQ) method of point SWE (Siemens Medical Solutions, Mountain View, CA) were conducted with a linear transducer (4-9 MHz) while the patients were in the supine position. Then we compared our VTQ measurements with pathologic results. Results-The 36 patients included 31 female and 5 male patients with a mean age +/- SD of 49 +/- 15.7 years (range, 15-79 years). The mean SWV of parathyroid hyperplasia lesions (n = 4) was 1.46 +/- 0.23 m/s, whereas the mean SWV of parathyroid adenomas (n = 32) was 2.28 +/- 0.50 m/s. The mean SWV of normal thyroid parenchyma (n = 36) was 1.62 +/- 0.20 m/s, and the mean SWV of benign thyroid nodules (n = 21) was 2.25 +/- 0.51 m/s. A significant difference was found between SWV values of normal thyroid parenchyma and parathyroid adenoma (P<.001). A cutoff value of 1.73 m/s for adenomas led to 90.0% sensitivity and 80.6% specificity. Conclusions-The VTQ method of point SWE may contribute to the discrimination of parathyroid adenomas from the thyroid gland. However, more comprehensive studies are needed.

    Ön Çapraz Bağ Greft Rekonstrüksiyonunda Görüntüleme Bulguları
    (2018) Göya, Cemil; Teke, Memik; Hamidi, Cihad; Durmaz, Mehmet Sedat; Hattapoğlu, Salih
    Amaç: Ön çapraz bağ (ÖÇB) greft rekonstrüksiyonunun postoperatif direkt grafi , manyetik rezonans görüntüleme(MRG) normal bulgularını tanımlamak, operasyon sonrası gelişebilecek potansiyel komplikasyonlarının MRG bulgularını sunmaktır.Gereç ve Yöntemler: Çalışmaya ÖÇB rekonstrüksiyon cerrahisi geçirmiş 52 hasta alındı. Hastaların direkt grafi , manyetik rezonans görüntüleri ÖÇB greft bütünlüğü ve eşlik edebilecek komplikasyonlar açısından retrospektif olarak değerlendirildi.Bulgular: Çalışmaya alınan 52 hastanın 18'inde postoperatif patolojik bulgular saptandı. Dört hastada total greft rüptürü, bir hastada parsiyel greft rüptürü, iki hastada gevşek greft, 10 hastada anterior yerleşimli tibial tünel, sekiz hastada tepe impigement, iki hastada yan duvar impigement, dört hastada tünelde kistik genişleme, bir hastada patellar fraktür, iki hastada operasyon materyaline bağlı iliotibial band sürtünme sendromu ve dört hastada artrofi brozis saptandı.Sonuç: MRG, ÖÇB greftinin, tünellerin ve fi ksasyon materyallerinin pozisyonunu değerlendirmede, operasyon sonrası ağrı ve fonksiyon kaybının nedenini araştırmada kullanılabilen etkili bir görüntüleme yöntemidir.

    Pelvic And Bilateral Symetric Lower Extremities Involvement Of Extensive Fetal Cystic Lymphangioma: A Case Report
    (Düzce Üniversitesi, 2015) Dusak, Abdurrahim; Durmaz, Mehmet Sedat; Bilici, Aslan; Alan, Bircan
    Extensive fetal cystic lymphangioma is a rare congenital malformation of the lymphatic system.Their prognosis depends on the size and location of the lesions as well as other accompanyinganomalies. Our case was 35 years, fetal BPD was 27 weeks . Herein, we present a case ofextensive fetal cystic lymphangioma that began at the pelvic area and symmetrically spannedthe bilateral proximal and distal lower extremities. Numerous extensive and sharplycircumscribed, thin walled multilobular cystic lesions in different sizes were observed in thesubcutaneous superficial and deep soft tissue beginning from the pelvic area and extending toboth lower extremities to the distal in the fetüs. To our knowledge, a case involving bothextremities has not yet been reported in the literature

    Quadriorchidism: A case of bilateral supernumerary testicle and review of the literature
    (2018) Hamidi, Cihad; Göya, Cemil; Hattapoğlu, Salih; Durmaz, Mehmet Sedat; Özbakır, Bora
    Polyorchidism, which means one or more additional testicles, is a congenital anomaly and is seldomobserved. In many polyorchidism patients, there is one supernumerary testicle (SNT) (triorchidism)whose left face is often the presentation. Two-sided SNT is very rare, and has been reported only insix cases. Here, we are presenting a male case who was six years old with bilaterally SNT(quadriorchidism) in scrotum that presented as asymptomatic masses.
