Conjoined lumbosacral nerve roots
Konjenital anatomik anomaliler arasında lumbosakral sinir kökü anomalileri nadir görülen bir gruptur. Literatür incelendiğinde çok farklı lumbosakral sinir kökü anomalilerinin raporlandığı gözlenebilmektedir. Bu anomalilerin alt grupları kabaca bifid, birleşik yapı, transvers yönde veya anostomozlaşmış yapıda olmaları şeklinde sınıflandırılmaktadır. Görüntüleme yöntemlerinin gelişmesinden önce bu yapılar otopsi çalışmaları ve lumbar disk herniasyonuna yönelik cerrahi girişimler sırasında insidental olarak gözlenmiştir ve çoğunlukla asemptomatikirler.Lumbosacral nerve root anomalies are a rare group of congenital anatomical anomalies. Various types of anomalies of the lumbosacral nerve roots have been documented in the available international literature. Tthese anomalies may consist of a bifid, conjoined structure, of a transverse course or of a characteristic anastomized appearance. Firstly described as an incidental finding during autopsies or surgical procedures performed for lumbar disk herniations and often asymptomatic, lumbosacral nerve root anomalies have been more frequently described in the last years due to the advances made in radiological diagnosis
Isolation and Identification of Mycoplasmas from pneumonic lungs of cattle by 16S rDNA and DGGE
Misdiagnosed chest pain: Spontaneous esophageal rupture
Chest pain is one of themost common complaints expressed by patients presenting to the emergency department, and any initial evaluation should always consider life-threatening causes. Esophageal rupture is a serious condition with a highmortality rate. If diagnosed, successful therapy depends on the size of the rupture and the time elapsed between rupture and diagnosis.We report on a 41-year-old woman who presented to the emergency department complaining of left-sided chest pain for two hours
Effectiveness of the STIR turbo spin-echo sequence MR imaging in evaluation of lymphadenopathy in esophageal cancer
Alper, Fatih/0000-0002-9483-8861; Acemoglu, Hamit/0000-0002-4667-8103WOS: 000296763300069PubMed: 20800403Purpose: We have investigated the utility of the STIR TSE sequence in the differentiation of benign from malignant mediastinal lymph nodes in patients with esophageal cancer. Patients and methods: This study included 35 consecutive patients who were diagnosed as esophageal cancer and were undergone surgery. STIR TSE sequences were obtained as the ECG trigger. The signal intensity of the benign and malign lymph nodes, normal esophagus, and pathologic esophagus can be calculated on STIR sequence. Results: Pathologically, the number of total lymph nodes in 35 operated cases was 482. Approximately 152 lymph nodes were detected with MR imaging. Of these, 28 were thought to be malignant, and 124 were thought to be benign, although 32 were malignant and 120 were benign according pathological results. The ratio of benign lymph node intensity value to normal esophagus intensity value was 0.73 +/- 0.3. The ratio of malignant lymph node intensity value to normal esophagus intensity value ratio was 2.03 +/- 0.4. According to these results, the sensitivity of MR was 81.3%, the specificity was 98.3%. Conclusion: We think that if motionless images can be obtained with MRI, we may be able to differentiate benign lymph nodes from malignant ones. (C) 2010 Elsevier Ireland Ltd. All rights reserved
