RESUMO

OBJECTIVE: To assess the value of placental shear wave velocity (SWV) measurement by acoustic radiation force impulse (ARFI) imaging for the diagnosis of pre-eclampsia and to determine the relationship between the SWV and the severity of pre-eclampsia. METHODS: A prospective study was performed at a center in Turkey between August 2014 and March 2015. The study included consecutive pregnant women in the second or third trimester diagnosed with pre-eclampsia and healthy pregnant women without pre-eclampsia of similar ages. Patients with pre-eclampsia were divided into two groups (severe or mild disease) on the basis of revised American College of Obstetricians and Gynecologists criteria. All patients underwent ARFI, and the SWV was measured at several placental locations. RESULTS: Overall, 86 women were enrolled (42 with pre-eclampsia, 44 controls). Minimum, maximum, and mean SWV values were significantly higher in the pre-eclampsia group than in the control group (P<0.001 for all). These values were also significantly higher among patients with severe pre-eclampsia than among patients with mild pre-eclampsia (P<0.001 for all). CONCLUSION: Measurement of the placental SWV with ARFI imaging is a useful additional method for the diagnosis of pre-eclampsia and for determination of the disease severity.

RESUMO

AIM: Given the lack of studies evaluating pituitary iron overload in patients with thalassemia major, we used magnetic resonance imaging (MRI) to evaluate these patients and the factors affecting the disease process. MATERIALS AND METHODS: The 84 patients with ß-thalassemia major who were included in this study were referred to our clinic for cardiac and hepatic T2(*) MRI. T2(*)-weighted images of the pituitary gland, heart, and liver were obtained using a 1.5-tesla MRI unit and a multi-echo gradient-echo sequence. Associations between pituitary T2(*), cardiac T2(*), hepatic T2(*), pituitary height, serum ferritin (SF) level, patient age, and other demographic findings were assessed. RESULTS: Pituitary T2(*) values correlated with hepatic T2(*) values, cardiac T2(*) values, SF level, and patient age (P≤0.001, 0.001, 0.001, 0.01, respectively) but not with pituitary height (P=0.76). Pituitary and cardiac T2(*) values were lower in the subset of patients who underwent splenectomy (P=0.046 and P=0.002, respectively). CONCLUSION: Pituitary iron overload rapidly increases during puberty and in this study correlated with cardiac and hepatic T2(*) values, patient age, SF level, and liver size, but not with the height of the pituitary. Pituitary iron overload also increases following splenectomy. Together, these findings indicate that numerous factors contribute to pituitary iron overload.

RESUMO

BACKGROUND: Computed tomography (CT) is the gold standard for assessing interstitial lung disease (ILD) in patients with systemic sclerosis (SSc). In this study, we performed a quantitative calculation of ILD severity by examining the lung volume of SSc patients. METHODS: The present study was performed retrospectively on 38 patients with SSc who were referred to our clinic. Patients were divided into two groups based on high-resolution computed tomography (HRCT): patients with ILD and patients without ILD.The percentage of lower lobe volume (PLLV) was calculated using HRCT. In addition, we evaluated the PLLV in all patients according to age, diffusing capacity of the lung for carbon monoxide (DLCO) and spirometric findings, and assessed the relationships among these factors. RESULTS: PLLV of the right lung in patients with ILD was reduced when compared with patients without ILD (P=0.041). The PLLV of the right lung in patients with ILD was negatively correlated with age and forced vital capacity (FVC; P=0.01 and P=0.012, respectively). CONCLUSIONS: The PLLV of the right lung may decrease in SSc patients with ILD. In these patients, the PLLV may be a quantitative parameter indicating damage in the lung.

RESUMO

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/mm(2) (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/mm(2) (p<0.001) and 1600 s/mm(2) (p<0.001). A cutoff value of 1.902 × 10(-3) mm(2)/s for the ADC with a b value of 800 s/mm(2) provided 88% sensitivity and 96% specificity for differentiation between benign and malignant renal lesions. A cutoff value of 1.623 × 10(-3) mm(2)/s for the ADC with a b value of 1600 s/mm(2) 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.

RESUMO

OBJECTIVES: To compare the diagnostic success rate of acoustic radiation force impulse (ARFI) elastography with those of sonography and computed tomography (CT) for acute pancreatitis at hospital admission. METHODS: B-mode sonography and ARFI elastography were performed on 88 patients with symptoms of acute pancreatitis and 50 healthy control participants who were admitted to our hospital between February 2013 and July 2013. Acute pancreatitis was verified in the 88 patients based on clinical and laboratory findings. Computed tomography was performed on 41 patients, and the CT results from these patients were compared with those of ARFI elastography. The appearances of the pancreases of the patients were classified into 6 groups using visual color encodings obtained with ARFI elastography. The elasticity values of pancreatic head, body, and tail regions were evaluated with Virtual Touch imaging and Virtual Touch tissue quantification (Siemens Medical Solutions, Mountain View, CA). The success rates of sonography, CT, and ARFI elastography for diagnosing acute pancreatitis at hospital admission were compared. RESULTS: Forty-six of the 88 patients had a diagnosis of pancreatitis by B-mode sonography; pancreatitis was diagnosed in all patients by ARFI elastography; and 10 of 41 patients could not be diagnosed by CT. The sensitivity and specificity of Virtual Touch tissue quantification were 100% and 98%, respectively, when a cutoff value of 1.63 m/s was used. The control group had color scores of 1 or 2, whereas all patients with pancreatitis had color scores of 3 to 6 on color scale evaluation with Virtual Touch imaging. CONCLUSIONS: Acoustic radiation force impulse elastography is a rapid, radiation-free, and noninvasive tool for diagnosis of acute pancreatitis at initial hospital admission, with a higher success rate for diagnosis of acute pancreatitis than the grayscale sonography and CT.

RESUMO

BACKGROUND: The objective of this study was to retrospectively investigate and compare multidetector computed tomography findings of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-positive and -negative patients. METHODS: Triphasic (arterial, portal venous, and delayed phases) dynamic multidetector computed tomography (CT) was performed in 83 patients with HCC, 48 of whom were HBV-positive. The diagnosis of HCC was established with typical CT imaging findings (68 patients) or histopathological evaluation (15 patients). Distribution of solitary, multiple, and diffuse HCC, portal/hepatic vein thrombosis, metastasis, and patients with high alpha-fetoprotein levels in the HBV-positive and -negative groups were compared using the Kolmogorov-Smirnov test. Lesion size, alpha-fetoprotein levels, arterial, portal, delayed enhancement, and washout of lesions were compared using the Student's t-test. RESULTS: Hypervascular tumors were observed in 72 (87%) patients, and hypovascular tumors were found in 11 (13%) patients. The mean alpha-fetoprotein value of HBV-positive patients with HCC was significantly higher than the mean alpha-fetoprotein value of HBV-negative patients (P < 0.05). Portal/hepatic vein thrombosis and metastasis were more frequently observed in HBV-positive patients (P < 0.05). The frequencies of solitary, multiple, and diffuse lesions in HBV-positive and -negative patients were not significantly different (P > 0.05). The mean diameters, arterial, portal, and delayed phase attenuations, and washout of HCC were not significantly different (P > 0.05). CONCLUSIONS: Multidetector CT imaging findings of HCC in HBV-positive and -negative patients are alike. Portal/hepatic vein thrombosis and metastasis are more frequently observed in HBV-positive patients. Alpha-fetoprotein levels are higher in HBV-positive patients.

RESUMO

BACKGROUND: Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. CASE REPORT: We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn't have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. CONCLUSIONS: Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions.

RESUMO

PURPOSE: The gallbladder and the biliary tract are structures in close connection with the adjacent organs and may show a number of variations and anomalies. It is therefore important for surgical purposes to know their anatomy and variations in detail. Various methods are used in the imaging of the variations of the biliary tract and its pathologies, including ultrasonography, computed tomography; direct cholangiographic methods like endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, intravenous cholangiography and T-tube cholangiography, as well as indirect methods like magnetic resonance cholangiopancreatography (MRCP) or cholescintigraphy. The aim of this study is to investigate the frequency of the anatomic variations of the biliary tract using 3-T MRCP and to compare the findings with the data in the literature. MATERIALS AND METHODS: For the purposes of this study, patients who underwent MRCP at our hospital (Dicle University Hospital) between November 2009 and February 2012 were investigated retrospectively. A total of 590 patients (between 6 and 88 years of age; mean age: 51 ± 9 years) were included in the study. The MRCP imaging was carried out with an magnetic resonance imaging (MRI) device supplied with 3-T magnetic power and by obtaining T2-weighted images through the single-shot fast spin echo technique using the standard body coil. The axial and coronal source images and the reformatted images were evaluated together in terms of the possible anatomic variations. RESULTS: Among the 590 patients included in the study, of 233 (39.5 %) showed anatomic variations at different levels in the intra- and extrahepatic biliary tracts. Among these variations, a right posterior hepatic duct insertion to the left hepatic duct at the level of the bifurcation has been observed in 71 patients (12.1 %), trifurcation was observed in 30 patients (5.1 %) and insertion into the main hepatic duct at the proximal aspect of the cystic duct was observed in 18 patients (3.1 %). At the level of the cystic duct, medial insertion of the cystic duct was viewed in 58 patients (9.8 %), distal medial insertion was seen in 40 patients (6.8 %), a short cystic duct was detected in 10 patients (1.7 %), pancreatobiliary junction anomaly was viewed in two patients (0.4 %) and duplicate anatomic variations have been observed in 42 patients (7.2 %). CONCLUSION: MRCP studies conducted using 3-T MRI devices may reveal similar or greater numbers of variations when compared to the existing MRCP studies in the literature. 3-T MRI shows a couple of variations. Pointing out these anatomical variations before the surgical intervention may prevent possible iatrogenic traumas. Donors with unsuitable variations for liver transplant may be spotted out at an early phase through the MRCP and certain operations with a high morbidity rate may thus be avoided.

RESUMO

The aim of this study is to investigate the frequency of the SHC variations, and the distribution of the SP lengths in different age and sex groups using MDCT. MDCT scans were performed in 805 patients (401 males, 404 females). The patients were divided into six groups according to their ages. The length of the styloid process (SP) and its angulation on the transverse (TA) and sagittal (SA) planes were measured. Structural variations of the SHC were observed by means of three-dimensional (3D) and multiplanar reconstruction (MPR) images. Absence of the styloid process (n = 10), double proximal origin (n = 13), segmentation (n = 223), complete ossification (n = 24), and an SP with three proximal parts in one patient were among the anomalies detected. The mean length of the SP was greater in males than in females (33.2 ± 13.2 vs. 29.6 ± 10.5 mm, P < 0.001). Elongated SP (ESP) was observed in 56 % of the patients in the study group, and this ratio was the highest in Group 3 with 65.4 % (P < 0.05). TA and SA were 70.2° ± 4.1°, 69.9° ± 4.2° and 86.6° ± 6.5°, 88.3° ± 6.6° for the right and left sides, respectively. Besides, 3D and MPR images also present detailed and reliable data to radiologists and surgeons for the evaluation of the SHC. ESP has been detected in more than half of the patients, being more frequent in males and in individuals in the fifth decade of life. For an accurate diagnosis, clinicians should consider the ESP while evaluating the patients in this age group.

RESUMO

BACKGROUND: This article is concerned with the evaluation of an adolescent breast mass using imaging methods. CASE REPORT: A 14-year-old girl presented with progressive asymmetric enlargement of the left breast. She had felt a breast lump about 4 months earlier, and over the last 2 months it had been growing progressively. Tumor markers, including AFP, CEA, CA15-3, and CA125, were all normal. Ultrasonography showed a hypoechoichyperechoic, solid mass. Magnetic resonance imaging of the breast revealed a well marginated mass with hypointensity on T1-weighted images and mild hyperintensity on T2-weighted images, which showed mild contrast uptake. Biopsy revealed an undifferentiated malignant mesenchymal sarcoma. The patient underwent mastectomy with axillary lymph node sampling. After the operation, she received 3 cycles of chemotherapy and radiotherapy. CONCLUSION: Due to the rarity of breast sarcoma and inadequate imaging methods to establish an exact diagnosis, radiologists and clinicians may misdiagnose and merely follow these tumors. As in our case, the histology of the patient may be the leading factor in the management of these tumors. Even in very young patients, progressively growing breast masses should alert the clinician to check for malignancy verified by biopsy.

RESUMO

PURPOSE: The goal of our study was to measure the prevalence of anomalies in the extracranial segment of internal carotid artery (ICA), to measure the carotid-pharyngeal distance (CPD). METHODS: Computed tomography (CT) angiography images of 607 patients were retrospectively examined. The course anomaly and CPD were obtained at different image plane. The patients were divided into four groups according to their age. RESULTS: The incidence of course anomaly in ICA was shown to be 60.3 %. Prevalence of course anomaly showed an increase with age (p < 0.001). Women had more ICAs with a course anomaly than men (p < 0.001). Mean CPD among all ICAs was found to be 11.13 mm. When CPD values were compared between the groups, group 1 and group 2 did not have a significant difference, however, there was a significant difference between other groups (p < 0.05). The CPD significantly decreased with age (p < 0.001). In ICAs that showed a straight course, the mean CPD was 13.0 mm, while in ICAs that showed course anomaly, the mean CPD was determined to be 9.49, showing a significant difference (p < 0.05). CONCLUSION: In conclusion, the number of ICAs that show a course anomaly increases with age, while the CPD decreases. The CPD is decreased in groups that show anomalies. The detection of a decreased CPD before surgery may lower the chance of a perioperative hemorrhage due to artery damage during pharyngeal procedures. Hence, while reporting neck CT angiographies, it may be valuable to also report the presence of ICA anomalies and CPD.

RESUMO

A 20 year-old man presented with pain and swelling of the left submandibular area. Neck sonography revealed enlargement of the submandibular gland, coarsening of its echotexture with a few calculi and a multiloculated cystic lesion. Doppler sonography revealed venous flow within the cystic lesion and aneurysmal dilatation of the adjacent facial vein. CT angiography confirmed the facial vein aneurysm. We hypothesize that inflammation of the gland had weakened the wall of the adjacent facial vein, causing aneurysmal dilatation.

RESUMO

UNLABELLED: Pulmonary Veins are one of the major structures of circulation. In the last decade, pulmonary veins have been known to play an important role as the triggering focus of the electrical activity in atrial fibrillation. Primary treatment method of AF is RF ablation of the focus. For the best ablation, the anatomy of PVs should be well established before the procedure. MATERIAL AND METHODS: In our radiology department, 783 patients underwent computed tomography angiography between January 2008 and May 2010. Patients were referred for coronary CTA because of known or suspected coronary artery disease or computed tomography pulmonary angiography (CTPA) because of known or suspect pulmonary embolism. All scanning was performed on Philips Brilliance 64 slice Multidetector CT. The group consisted of 402 male and 381 female patients with the average age of 48 (range 14-89). CT data of patients were retrospectively reviewed to identify the PV anatomy and to determine anatomic variants and anomalies. RESULTS: In the majority of cases, two pulmonary veins drain into the left atrium on each side. Eighteen and eight variations were found in the right and left sides, respectively. Most frequent combined variations were 2R-4L (32.3%) and 4L was the more frequent single variation type (76%). In addition to that one Situs inversus totalis (0.12%), two partial anomalous pulmonary venous returns (0.25%) and one scimitar syndrome (0.12%) were found. CONCLUSION: This study showed that multiple types of variations of PVs can be found with increasing patient number. Therefore, for the successful ablation and surgery without any complications, the anatomy of PVs should be known before the procedure. MDCT is a reliable imaging method for the detailed cross-sectional and 3D anatomy.

RESUMO

Blue rubber bleb nevus syndrome (BRBNS) is a rare entity that consists of multiple venous malformations involving several organ systems, particularly the skin and the gastrointestinal tract. The diagnosis is based on clinical findings; however, imaging is required to investigate the extent of involvement and complications. A 17-year-old patient, with multiple blue skin nevus, was admitted to the emergency room of our hospital with severe gastrointestinal bleeding and melena. Upper endoscopy showed two wine-color vascular lesions in the duodenum, and colonoscopy revealed multiple lesions in the colon. Peroral CT enterography demonstrated multiple (more than 30) contrast-enhanced polypoid small bowel lesions, ranging in size from 5 to 16 mm. Some lesions contained millimetric calcifications representing phleboliths. The patient also had three pancreatic lesions which showed homogenous enhancement on the delayed images. Our findings show that peroral CT enterography is useful to demonstrate the extent of small bowel lesions of BRBNS. This is the first report of pancreatic involvement of BRBNS.

RESUMO

Obscure gastrointestinal bleeding is an important dilemma. Brunner's gland hamartoma is an extremely rare tumor generally localized in the duodenal bulb. We present a 34-year-old woman who had suffered from several episodes of melena for the past three years. Endoscopic examinations were normal. Computed tomography showed a large target lesion over the right abdomen and an image representing intestinal malrotation, which was supported by enteroclysis. At exploratory laparotomy, ligamentum of Treitz was located in the mid-to-right side of the columna vertebralis, and the duodenal bulb was found to be invaginated into the proximal jejunum. After longitudinal duodenotomy, a pedunculated ring-shaped large polyp originating from the pyloric ring was seen and excised. Histology was consistent with Brunner's gland hamartoma. This case with obscure bleeding was original with respect to its rarity and being a huge, ring-shaped tumor with pyloric localization. Moreover, the patient had a rare clinical presentation of duodenojejunal intussusception with accompanying intestinal malrotation.

RESUMO

A 25-year-old woman who had undergone the Blalock-Taussig shunt operation for double-outlet right ventricle (DORV) in her childhood was admitted to our hospital with mild cyanosis and dyspnea on exertion. To evaluate the precise complex anatomy of this abnormality, we carried out multidetector computed tomography (MDCT) angiography. MDCT clearly revealed both an occluded Blalock-Taussig shunt and a complex cardiac anatomy, including DORV, a doubly committed ventriculoseptal defect, pulmonary stenosis, persistent left superior vena cava, minor aortic arch anomalies, and total anomalous hepatic venous drainage. To our knowledge, our report is the first description of such a complex cardiac anatomy to be revealed with MDCT.

RESUMO

OBJECTIVE: Our objective was to describe the technique and outcome of CT-guided injection of botulinum toxin into the diaphragmatic crus in a patient with hypertension caused by left diaphragmatic crus compression of the left renal artery. CONCLUSION: After the procedure, the patient's hypertension disappeared. We propose this technique, which directly targets inhibition of overactivity of the diaphragmatic crus, for treatment of hypertension caused by diaphragmatic compression of the renal artery as an alternative to surgery and renal artery stenting.

RESUMO

OBJECTIVE: The classical findings in hydatid disease caused by Echinococcus granulosus with liver or lung involvement are well known. However, diagnosing hydatid disease at unusual locations may be challenging because of variable imaging appearances depending on the host reaction. The purpose of this pictorial essay is to review the sonographic, CT, and MRI features of extrahepatic abdominal hydatid disease including intraperitoneum, retroperitoneum, diaphragma, bone, and soft tissue of the abdomen. CONCLUSION: Extrahepatic abdominal hydatid lesions have nearly identical imaging features, including the presence of cyst wall calcification, daughter cysts, and membrane detachment. The combinations of radiologic and serologic tests especially in patients living in the endemic areas contribute to the diagnosis. Despite their rarity, being familiar with the spectrum of radiologic findings in these unusual sites is helpful to improve diagnostic accuracy.

RESUMO

The urachus is a midline tubular structure that extends upward from the dome of the bladder toward the umbilicus. This tubular structure normally involutes before birth, remaining as a fibrous band with no known function. Persistence of all or any portion of the fetal urachus results in several anomalies, the most common of which is the urachal cyst (Yu JS, Kim KW, Lee HJ, Lee YJ, Yoon CS, Kim MJ, Radiographics, 21:451-4611, 2001; Ohgaki M, Higuchi A, Chou H, Takashina K, Kawakami S, Fujita Y, Hagiwara A, Yamagishi H, Surg Today, 33:75-77, 2003). Although most urachal cysts are asymptomatic, there are a few reports about intraperitoneal rupture of infected urachal cysts, all of which caused peritonitis and sepsis (Ohgaki M, Higuchi A, Chou H, Takashina K, Kawakami S, Fujita Y, Hagiwara A, Yamagishi H, Surg Today, 33:75-77, 2003; Kojima Y, Miyake O, Taniwaki H, Morimoto A, Takahashi S, Fujiwara I, Int J Urol, 10:174-176, 2003; Agatstein EH, Stabile BE, Arch Surg, 119:1269-1273, 1984). We report the imaging and operative findings of a patient, presented with a urachal abscess after a spontaneously ruptured urachal cyst.

RESUMO

OBJECTIVE: To investigate the efficacy of medical antituberculous treatment in patients with tuberculous cervical lymphadenitis (TCL). METHODS: In the period 1996-2002, 73 TCL patients were reviewed and the results of clinical and laboratory testing were documented. The efficacy of a four-drug chemotherapy regimen was investigated. RESULTS: Purified protein derivatives (PPD) skin test results were positive in 58 (79 per cent) patients. Chest X-rays revealed changes consistent with tuberculosis in nine (12.3 per cent) patients. The mean duration of medical treatment was 10.04 months. In follow-up evaluation, 14 (20 per cent) patients were considered suspicious for resistant TCL and total excision of all nodes was performed. Histopathology confirmed TB in only 10 of these cases. CONCLUSION: The high incidence of residual disease in our study indicates that medical treatment (at least nine months of four combined antituberculous drugs) did not seem to be effective. If lymphadenopathy persists, total surgical excision of lymph nodes should be the treatment of choice.
