Abstract
BACKGROUND Denim sandblasting-induced silicosis is a recently identified occupational disease. AIMS In this study, we aimed to evaluate pulmonary and radiological changes in the long-term follow-up of former denim sandblasters. METHODS Ninety former denim sandblasters were followed from 2007 to 2018. Chest X-rays were evaluated according to the International Labour Organization (ILO) classification. Baseline and final data were compared. Silicosis prevalence, radiological progression and pulmonary dysfunction were evaluated. RESULTS All of the sandblasters were men. Their mean age was 34 ± 5 years, mean follow-up time was 9 ± 2 years (mean time since initial exposure: 17 ± 2 years) and mean duration of exposure was 34 ± 25 months. Rates of radiological progression and decline in pulmonary during follow-up were 63% and 39%, respectively. During follow-up, all patients were diagnosed with silicosis. All workers who were ILO category 0 at baseline (n = 26, 29%) progressed to higher categories. The number of patients in Category 2 doubled and the number of patients in Category 3 increased by 2.5-fold. Eleven patients developed new large opacities and the number of patients with category C opacity increased from 4 to 13. Exposure time was an independent determinant of radiological progression (OR: 1.0, P = 0.036) and decline in pulmonary function (OR: 1.3, P = 0.019). CONCLUSION The prevalence of silicosis in denim sandblasters increases steadily even after exposure is discontinued. Radiological progression was observed in a higher proportion of workers than a decline in lung function. Duration of exposure was the major determinant of disease progression in our study.

Abstract
AIM To evaluate the density and volume changes in the lungs of silicosis patients and their relationship with the disease severity classification of the International Labor Organization (ILO). MATERIALS AND METHODS The multidetector computed tomography (CT) images of 44 patients diagnosed with silicosis and 32 controls that underwent thoracic CT due to trauma were evaluated. Patients with silicosis were divided into three categories according to the ILO classification. Data related to the total lung volume, total lung mean density, lung opacity score, percentage of lung high opacity, and mean density in the lower and upper lobes were obtained using three-dimensional (3D) software. RESULTS There was no significant difference between the total lung mean densities of the silicosis and control groups (p=0.213); however, a significant difference was observed between the two groups in terms of the total lung volume (p<0.0001). According to the ILO classification, there was a significant difference between the disease severity categories in relation to the percentage of lung high opacity (p=0.000005). A strong correlation was detected between disease severity and high opacity percentage (p<0.0001, r=0.804). According to the ILO classification, there was also a significant difference between disease severity categories in terms of the lung opacity score (p=0.000144), as well as a moderate correlation between disease severity and opacity score (p<0.0001, r=0.580). CONCLUSION Total lung volume is a CT finding that shows variation in exposure to crystalline silica. The percentage of high opacity determined using multidetector CT is an effective parameter in evaluating disease severity.

Abstract
BACKGROUND In this study, we investigated the relationship between the portal vein and hepatic artery variations and the remaining liver volume in living donors in liver transplantation. MATERIALS AND METHODS In the study, triphasic abdominal computed tomography images of 180 live liver donor candidates were analysed retrospectively. Portal veins were divided into four groups according to the Nakamura classification and seven groups according to the Michels classification. The relationship between vascular variations and remnant liver volume was compared statistically. RESULTS According to the Nakamura classification, there were 143 (79.4%) type A, 23 (12.7%) type B, 7 (3.9%) type C and 7 (3.9%) type D cases. Using the Michels classification, 129 (71%) type 1, 12 (6.7%) type 2, 24 (13%) type 3, 2 (2.2%) type 4, 10 (5.6%) type 5, 1 (0.6%) type 6, and 2 (1.1%) type 7 cases were detected. There was no significant difference in the percentage of the remaining volume of the left liver lobe between the groups (p = 0.055, p = 0.207, respectively). CONCLUSIONS Variations in the hepatic artery and portal vein do not affect the remaining liver volume in liver transplantation donors.

Abstract
After excluding alternative explanations, a silicosis diagnosis is based on the combination of appropriate silica exposure history and compatible clinical, radiological and occasionally pathological findings. Not taking appropriate occupational history by a physician may cause a misdiagnosis or underdiagnosis of silicosis. Herein, we present a female worker in a small-scale sandblasting factory who worked as a controller. Her silicosis diagnosis was established 10 years after her first symptoms, and she underwent invasive procedures due to a lack of inquiry about her occupational history. Gender bias may be one of the reasons that her occupational history was not taken.

Abstract
Congenital pathologies of the inferior vena cava are uncommon. Isolated congenital interruption of the inferior vena cava with azygos vein continuation could be considered part of the group of venous return anomalies. The major significance of this anomaly is its association with complex cardiac defects and the associated technical difficulties at the time of cardiac catheterization and abdominal surgery or interventional procedures. In our case, we describe a common atrium and partial atrioventricular septal defect in an 8-year-old girl with infrahepatic interruption of the inferior vena cava and azygos continuation without polysplenia. Magnetic resonance angiography and computed tomography, together with a clinical awareness of this pathology, can be used to diagnose this entity.

Abstract
To review clinical, radiological and histopathological findings of adult intussusception and its management, 18 adult patients who had been treated surgically because of intussusception were reviewed. Of the patients, 5 (27.8%) had idiopathic intussusceptions, while the other 13 (72.2%) had a definable intraluminal pathology. The site of the intussusception was more common in the small bowel (83.3%) than the colon (16.7%). Ultrasonography and computed tomography were successful in demonstrating "target lesion" in 80% and 75% respectively. Patients with idiopathic intussusception were treated with simple reduction, while the others underwent segmental resection because of the possibility of malignant tumour. In contrast to intussusception in childhood, intussusception in adults usually has a definable lead point and resection of the involved bowel, rather than simple reduction, is indicated.

Abstract
The purpose of this study was to determine the amount of atrophy occurring in the cerebrum of patients with multiple sclerosis compared with controls, and to show the relationship between clinical status and distribution of atrophy. MR images were obtained on 12 relapsing-remitting (RR) and 11 secondary progressive (SP) multiple sclerosis patients and 24 control subjects (all patients and controls were female). The Cavalieri method by modern design stereology was used to measure the cerebral volume. It was found that volumes for RR and SP with multiple sclerosis and control subjects were 757242 mm3, 716867 mm3 and 912499 mm3 respectively. Mean estimates of volume loss in RR and SP were 20.5% and 27.2% respectively compared to controls for the cerebrum. In addition the volume difference between RR and SP was 5.6%. There were statistically significant differences between both RR (P<0.05) and SP (P<0.05) compared with control subjects but no differences between RR and SP volumes. MRI-estimated cerebrum volumes may be help to evaluate patients' clinical status and provide a simple index to assess the efficiency of therapy.

Abstract
PURPOSE To determine brainstem volumes, number of plaques, and surface areas in the occipital lobes of patients with relapsing remitting multiple sclerosis (RRMS) and secondary progressive multiple sclerosis (SPMS), and to investigate whether there is any correlation between brainstem volume and the number/surface areas of plaque in the occipital lobes. MATERIAL AND METHODS Magnetic resonance imaging was obtained on 14 relapsing-remitting (RR) and 13 secondary progressive (SP) MS patients and 26 female control subjects. The Cavalieri method was used by modern design stereology to measure brainstem volume. The point-counting grid was used to evaluate sclerotic plaque surface areas in the occipital lobe. The number of plaques in the imaging section was calculated. RESULTS Brainstem volumes for RR and SP with multiple sclerosis and control subjects were 3647 mm3, 3515 mm3, and 4517 mm3, respectively. Mean number of plaques in the right-left occipital lobe was found to be 2.7-3.4 in RR-MS and 5.2-2.8 in SP-MS. Mean plaque surface area in the right-left occipital lobe was determined to be 58.52-88.24 mm2 in RR MS and 124.3-64.82 mm2 in SP MS. Brainstem volumes were significantly reduced in both groups of patients with MS compared to controls (P < 0.01). CONCLUSION Magnetic-resonance-estimated volume and surface area values in multiple sclerosis may facilitate our understanding of the clinical situation of patients and provide a simple index for evaluating therapeutic efficiency.

Abstract
PURPOSE To investigate the angulation, length, and structural variations of the styloid process (SP) by multidetector computed tomography (MDCT). MATERIAL AND METHODS MDCT scans were performed in 283 cases (127 M and 156 F, age range 18-77 years). The length of the SP and its angulation on the transverse and sagittal planes were measured. Structural variations of the SP were observed by means of three-dimensional (3D) and multiplanar reconstruction (MPR) images. RESULTS The length of the bony SP on both sides varied from 0 to 62 mm (mean 26.8 +/- 10.0 mm). Angulation ranged between 55 degrees and 90.5 degrees (7 2.7 +/- 6.6) in the transversal plane and between 76 degrees and 110 degrees (93.5 +/- 6.9) in the sagittal plane. Morphologically, the SP showed a considerable amount of variation. A solitary SP was present in 168 individuals (59.4%). In 9 individuals (3.1%), the SP was duplicated (4 unilateral and 5 bilateral). Sixty-one persons (21.6%) showed an incomplete ossified SP (42 unilateral and 19 bilateral), whereas in 7 individuals (2.5%) a bony SP was absent entirely (7 unilateral). In 38 individuals (13.4%), the stylohyoid ligament was ossified (16 entirely, 22 partial). In all individuals, 3D and MPR images showed the SP in its entire length. CONCLUSION MDCT with 3D CT and MPR of SP may show further detailed information related to SP. Not only the length of the SP, but also its 3D orientation, should be in focus in anatomical and clinical studies.

Abstract
SUMMARY. The purpose of the present study is to estimate tumor volumes of 10 patients with esophageal carcinoma on serial CT images that are obtained before and after chemoradiotherapy using a stereological method. In this study, tumor volume was measured using the Cavalieri method of modern design stereology with a combination of three separate stages. Firstly, detailed systematic series of axial CT images of 1-cm thickness were obtained throughout the whole tumor area of each subject and to magnify them all CT images were projected on a screen by overhead projector and then were marked by manually tracing the outline of areas with tumor on serial CT images that are projected onto the screen. Secondly these images were drawn on paper. Finally the images on paper were evaluated with a point-counting method. It was shown in a pilot study analyzed that 100 test points counted on about 6--8 serial slices through for esophagus wall, lumen and wall + lumen are sufficient to secure coefficient of error (CE) on the estimates of volumes as in this study. It was found that tumor volumes before and after radiotherapy for esophagus wall, lumen and wall + lumen was 10.34 cm(3), 1.15 cm(3) and 11.75 cm(3) before and 5.93 cm(3), 1.43 cm(3) and 7.65 cm(3) after radiotherapy, respectively. When only esophagus wall and lumen volumes or wall + lumen volumes before and after radiotherapy were statistically compared, the difference between either esophagus wall (P<0.01) and lumen (P<0.01) volumes or total volumes (P<.1) were significant. It is concluded that CT estimated tumor volumes may be helpful in both evaluating the clinical situation of patients and providing a simple index to assess the efficiency of therapy, prediction of tumor regression rate and minimizing the risk of chemoradiotherapy damage.

Abstract
We describe a 9-year-old child with a history of trichoptysis caused by intrapulmonary teratoma and we present the CT and MRI findings of the teratoma. A heterogeneous mass containing cystic and solid elements was detected on both CT and MRI scans. Histopathological examination confirmed the diagnosis of teratoma. Teratomas arising from lung parenchyma, as in this case, are extremely rare in childhood. In the thoracic region, the most common localization of teratomas is the anterior mediastinal compartment. We also discuss the CT and MRI findings and the differential diagnosis of teratomas.

Abstract
Superior vena cava syndrome is rare in infants, and rarely responds to conservative treatment. We report a 22-mo-old girl with superior vena cava syndrome due to the use of a central venous line and/or sepsis. Doppler study and computed tomography angiography of the neck showed thrombosis within the superior vena cava and jugular veins. She was admitted to a monitored setting and received recombinant tissue plasminogen activator for 2 d. The clinical features of superior vena cava syndrome disappeared completely 3 d after treatment. No complications were observed and radiological investigations showed blood flow through the thrombus after treatment. Systemic recombinant tissue plasminogen activator may be useful in the treatment of superior vena cava syndrome in children.

Abstract
Despite an increase in radical surgery for esophageal carcinoma, many patients continue to develop recurrent disease. Some reports have suggested that recurrent tumors should be treated aggressively with a combination of chemotherapy and radiotherapy. The aim of this study was to assess the comparative utility of computed tomography (CT) and magnetic resonance imaging (MRI) for the evaluation of recurrence after curative resection of cancer of the esophagus and gastroesophageal junction. To maximize survival benefit, detection of tumor recurrence as early and accurately as possible is important. Twenty-three patients who developed recurrent tumors after curative transthoracic esophagogastrectomy for esophageal carcinoma were analyzed retrospectively. The CT and MRI findings were correlated with pathology or with endoscopic and clinical follow-up. Primary tumor recurrence was detected at the anastomosis side in 19 patients (intraluminal mass in 13 and as diffuse or focal wall thickening in six). Distant recurrence was seen in the liver (n = 5), lung (n = 4), bone (n = 3), abdominal lymph node (n = 4), pleural effusion (n = 2) and pericardial effusion (n = 1). CT and MRI were found equal in showing the intraluminal mass, liver metastasis, pleural and pericardial effusion. Thickening of esophageal wall was demonstrated in nine patients using CT, but only seven of these tumor recurrences were confirmed by MRI, the remaining two were related to secondary fibrosis. Both CT and MRI showed diffuse gastric wall thickening determined as false tumor recurrence due to severe gastritis in one case. There were two (50%) false negatives for lung metastasis in MRI and one bone metastasis (33%) false negative in CT. CT was found superior in the demonstration of lung metastasis and MRI was superior in the evaluation of wall thickening and bone metastasis.

Abstract
Gorlin's syndrome (naevoid basal cell carcinoma) is an autosomal dominant tumor-predisposition syndrome, classically consists of multiple basal cell carcinomas of the skin, odontogenic keratocyst of the jaw, various skeletal abnormalities, and lamellar falx calcifications. Many associated lesions have been reported. We report a case of Gorlin's syndrome in a 22-year-old man in whom CT and MR images showed unusual findings of the thin corpus callosum and third ventricular cyst. We present a case of this syndrome with special emphasis on its unusual neuroradiological findings and radiological management.

Abstract
Diaphragmatic hernias are the most common abnormalities of gastrointestinal system especially in elderly patients. The radiographic findings of diaphragmatic hernias on esophagram are well known, but when incidentally found in an asymptomatic patient on axial computed tomography (CT) sections, the appearance of diaphragmatic hernia may mimic many other conditions. Our purpose is to present the CT findings of sliding hernia in an incidentally found asymptomatic patient, and to differentiate it from the other abnormalities that can be located in the distal paraesophageal area with the same appearance characteristics.

Abstract
The aim of this study was to assess the spectrum of radiographic findings in primary hyperparathyroidism (PHPT). The study group consisted of 16 women and 7 men whose Ca levels were at least two or three times higher than normal. The average age was 55.3 in women and 49.4 in men. We detected carcinoma in 1, hyperplasia in 1, multiple adenomas in 4, single adenoma in 17 patients. The most common finding in the skeletal system was the decreased bone mineral density (BMD) and the complete loss of the lamina durae dentium. BMD was found lower in women than in men. This result attributed the increased number of postmenopausal patients in our study group. The second most common finding in our study group was subperiosteal bone resorption. Brown tumors (BTs) were located at maxilla in one, widespread in one, mandibula in two, long tubular bones in four patients. Renal stone disease was found in five, spastic colon in two, gastric ulcer in one, mitral valve calcification in one patients. We demonstrated no pathologic changes consistent with PHPT in remaining seven patients.
