Retrospective Evaluation Of Percutaneous Treated Liver Cyst Hydatic Cases

INTRODUCTION: Our aim was to evaluate percutaneous treatment of hydatid cyst cases of liver and to evaluate the efficacy, complication rate of percutaneous treatment and the reasons for failure in patients who did not respond to treatment. METHODS: Our study is a retrospective study and percutaneous treatment of hydatid cyst cases of liver was performed in our interventional radiology unit between January 2012 and November 2018 and the patients who were followed up by our clinic were included in the study. Patients were evaluated in terms of age, sex, localization of the cyst in the liver, number of cysts treated, cyst types and cyst size. Our unsuccessful treatment criteria are; increased cyst size without septation-calcification, no change in cyst stage, extravasation and recurrence. RESULTS: In our study, a total of 119 percutaneous treatment was applied to 104 patients [38 (36.5%) males and 66 (63.5%) females]. The percutaneous cysts were 4-16 cm in diameter and the average diameter was 7.8 cm. Ninety two (77%) cysts were compatible with type 1, 25 (21%) type 2 and 2 (1.6%) type 3 cyst hydatid. One hundred one treatment (85%) were successful; 18 treatment (15%) were not successful. Five (28%) of the unsuccessful treatment had cystobiliary fistulization, 2 (11%) had extravasation, 3 (17%) had inadequate medical treatment and 8 (44%) had recurrence. DISCUSSION AND CONCLUSION: Percutaneous treatment in hydatid cyst is a highly effective method because of can be applied in more than one cyst in the same session and low complication rate

The utility of acoustic radiation force impulse imaging in diagnosing acute appendicitis and staging its severity

PURPOSEThe aim of this study was to investigate the feasibility of using acoustic radiation force impulse (ARFI) imaging to diagnose acute appendicitis.METHODSAbdominal ultrasonography (US) and ARFI imaging were performed in 53 patients that presented with right lower quadrant pain, and the results were compared with those obtained in 52 healthy subjects. Qualitative evaluation of the patients was conducted by Virtual Touch™ tissue imaging (VTI), while quantitative evaluation was performed by Virtual Touch™ tissue quantification (VTQ) measuring the shear wave velocity (SWV). The severity of appendix inflammation was observed and rated using ARFI imaging in patients diagnosed with acute appendicitis. Alvarado scores were determined for all patients presenting with right lower quadrant pain. All patients diagnosed with appendicitis received appendectomies. The sensitivity and specificity of ARFI imaging relative to US was determined upon confirming the diagnosis of acute appendicitis via histopathological analysis.RESULTSThe Alvarado score had a sensitivity and specificity of 70.8% and 20%, respectively, in detecting acute appendicitis. Abdominal US had 83.3% sensitivity and 80% specificity, while ARFI imaging had 100% sensitivity and 98% specificity, in diagnosing acute appendicitis. The median SWV value was 1.11 m/s (range, 0.6–1.56 m/s) for healthy appendix and 3.07 m/s (range, 1.37–4.78 m/s) for acute appendicitis.CONCLUSIONARFI imaging may be useful in guiding the clinical management of acute appendicitis, by helping its diagnosis and determining the severity of appendix inflammation

Akut Subdural Hematomlu 106 Olgunun Retrospektif Değerlendirilmesi

Amaç: ASDH (akut subdural hematom) olgularının klinik bulgularını ve bilgisayarlı tomografi sonuçlarını geriye dönük olarak değerlendirmek. Yöntemler: Ocak 2013 -Mart 2017 yılları arasında kliniğimize başvuran 106 ASDH olgusu geriye dönük olarak incelendi. Her bir olgunun yaş, cinsiyet, subdural hematometiyolojisi, ve BT(bilgisayarlı tomografi) sonuçları değerlendirildi. Olguların beyin BT kesitlerindeki orta hat şifti, hematom hacmi ve dansitesi hesaplanarak incelendi. Sonuçlar istatistiksel olarak değerlendirildi. Bulgular: Beyin cerrahi kliniğine başvuran 106 ASDH olgusunun [80 (%75,5) erkek, 26 (%24,5) kadın], ortalama yaş 37,93±27,16 (1-89) idi. Olguların 65’i (%61,3) kendiliğinden rezorbe oldu. Hastaların 23’ü (%21,7) ameliyat edildi. Bununla beraber olgulardan, 12’si (%11,3) erkek ve 6’sı (%5,6) kadın olmak üzere takiplerimiz esnasında eks olmuştur. Eks olguların kraniyal BT tetkiklerinde orta hat şiftine ek olarak kontüzyon, ödem veya diğer sistemik bulgular mevcuttu. En sık başvuru nedenleri trafik kazaları 48(%45), düşme 23(%22), darp 14(%13), ateşli silah yaralanması 11(%10), spontan kanamalar 10(%10) idi. Erkek ve kadın olgularda; hematom hacmi, dansitesi ve orta hat şifti açısından yapılan istatistiksel karşılaştırmada anlamlı farklılık bulunmadı. Olguların beyin tomografisi incelemesinde ortalama hematom hacimleri 22,54±2,45cm3 (4-120), ortalama subdural hematomdansitesi 52,35±15,12 HU (Hounsfield Units) (18-76), orta hat şifti 2,34±2,99mm (0-17,25) olarak ölçülmüştür. Yaş ile subdural hematom hacmi arasında yapılan korelasyon testi pozitif yönde anlamlı bulundu (p<0,001, r=0,425). Yaş ile hematomdansitesi arasındaki korelasyon testi negatif yönde anlamlı bulundu (p<0,05, r=-0,21). Sonuç: Çalışmamızda, acil polikliniğimize başvuran ASDH’li hastaları etiyolojik, klinik ve radyolojik olarak değerlendirdik. Bu hastalar için kraniyal BT önemli tanı araçıdır. KraniyalBT’deASDH’e ek bulguların olması mortaliteyi önemli ölçüde arttırmaktadır. ASDH’lı hastalarda yaş arttıkça hematom hacmi artmakta ve dansitesi düşmekteydi. Yaşlı hastalarda küçük travmalar sonrasında da ASDH oluşabilmekte ve geç bulgu verebilmektedir

Dyke-Davidoff-Masson syndrome (cerebral hemiatrophy): Radiological findings

Objective: The aim of this study was to present cross- sectional cranial imaging findings of cases with Dyke-Davidoff-Masson syndrome (DDMS). Methods: The findings of 16 cases in whom unilateral cerebral hemispheric atrophy was detected at computed tomography and/or magnetic resonance imaging were retrospectively evaluated. The cases consisted of 8 females and 8 males, the ages ranged between 5 and 53 (mean:24). Six of the cases were children and 10 were males. Five of the patients had CT and 13 had MRI scan. The images were retrospectively evaluated and cerebral parenchymal findings and compensatory cranial findings were noted. Results: All cases had unilateral cerebral hemispheric atrophy, ipsilateral cortical sulcal and lateral ventricular dilatation. Together with hemispheric atrophy ipsilateral atrophy of corpus callosum in 6 cases (37.5%), ipsilateral thalamic atrophy in 13 cases (81%), ipsilateral parahippocampal atrophy in 8 cases (50%), ipsilateral cerebral pedincular atrophy in 7 cases (44%) and ipsilateral pontine atrophy in 3 cases (19%) were detected. Gliotic signal changes were observed in 13 cases (81%). Of compensatory findings, unilateral calvarial thickening was focal in 4 cases (25%), and diffuse in 12 cases (75%). There was expansion in ipsilateral half of frontal sinus in 15 cases (94%) and expansion in temporal bone aeration in 5 cases (31%). Conclusion: DDMS is a syndrome presenting with findings of cerebral hemiatrophy and calvarial hypertrophy. Cross-sectional radiological imaging findings may be variable among cases

Bilateral cleft foot: Radiographic and prenatal ultrasound features of two siblings with a review of literature

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

The Role of Apparent Diffusion Coefficient Quantification in Differentiating Benign and Malignant Renal Masses by 3 Tesla Magnetic Resonance Imaging

Background: Diffusion-weighted magnetic resonance imaging (DWI) is a widely-accepted diagnostic modality whose efficacy has been investigated by numerous past studies in the differentiation of malignant lesions from benign entities. Aims: The aim of this study was to evaluate the efficiency of diffusion-weighted magnetic resonance imaging in the characterization of renal lesions. Study Design: Diagnostic accuracy study. Methods: A total of 137 patients with renal lesions were included in this study. The median apparent diffusion coefficient (ADC) values as well as the b 800 and b 1600 signal intensities of normal kidneys, solid components of mixed renal masses, and total cystic lesions were evaluated. Results: There were significant differences between the ADC values of lesions and normal renal parenchyma, and between the ADC values of benign and malignant renal lesions on DWIs at b values of 800 and 1600 s/mm² (p<0.001 and p<0.001, respectively). There were significant differences between the ADC values of Bosniak Category 1 and 2 cysts and the ADC values of Bosniak Category 1 and 3 cysts on DWIs at b values of 800 s/mm² (p<0.001) and 1600 s/mm2 (p<0.001). A cutoff value of 1.902 x 10-3 mm²/s for the ADC with a b value of 800 s/mm² provided 88% sensitivity and 96% specificity for differentiation between benign and malignant renal lesions. A cutoff value of 1.623 x 10-3 mm²/s for the ADC with a b value of 1600 s/mm² provided 79% sensitivity and 96% specificity (p<0.001) for the differentiation between benign and malignant renal lesions. Conclusion: Accurate assessment of renal masses is important for determining the necessity for surgical intervention. DWI provides additional value by differentiating benign from malignant renal tumors and can be added to routine kidney MRI protocols
