RESUMO

Rib graft is a common source of cartilage in rhinoplasty. Donor site choices for this resource were identified according to the authors who presented the introduction of this technique. However, the scientific basis of this valuable method lacks information, including the anatomical properties of costal cartilage. In this study, cartilage radioanatomy is examined and tested for if any estimators are present. A total of 148 thoracal CT scans of patients who applied to our facility were analyzed. Patients were divided per their sex and age of 35, and rib cartilage dimensions, including axial length between the sternal and costal ends of the cartilage (TotL), posteroanterior diameters at the sternal end (StDia), costal end (CosDia), the thickest part (MaxDia) as diametrical parameters and vertical height at the thickest part (h) were recorded. Length of the sternum (St), the axial length of the clavicle (ClavL), the distance of the sixth rib from the anterior axillary border (AntAx), and thorax circumferences at the level of both pectoralis major muscle origin (ThC) and nipples (BrC) were recorded. Statistical analyses were done for correlations. St, ClavL, ThC, and BrC were found to have the most correlated measurements in groups with the age of 35 and less of both genders, and the relations were lost in older groups. Thorax shape may change after the age of 35 years, but in younger patients, St in females and ClavL in males can be used as estimators of cartilage amount.

RESUMO

OBJECTIVE: Peripartum cardiomyopathy (PPCM) diagnosis made by excluding identifiable causes of heart failure (HF) and occurs end of the pregnancy or during the postpartum period of five months. It presents a clinical HF spectrum with left ventricular systolic dysfunction. BACKGROUND: The purpose of this study is to retrospectively evaluate the clinical characteristics, cardiac magnetic resonance (CMR) imaging features, and end-points consisting of left ventricle recovery, left ventricular assist device implantation, heart transplantation, and all-cause mortality. METHOD: Outpatient HF records between 2008 to 2021 were screened. Thirty-seven patients were defined as PPCM. Twenty-five patients had CMR evaluation at the time of diagnosis, and six patients were re-evaluated with CMR. RESULTS: The mean age was 30.5 ± 5.6 years, and the mean LVEF was 28.2% ± 6.7%. In 13(35.7%) patients, LVEF recovered during the follow-up course. The median recovery time was 281(IQR [78-358]) days. LVEF on CMR was 35.3 ± 10.5, and three patients exhibited late gadolinium enhancement(LGE) patterns. Sub-endocardial and mid-wall uptake pattern types were detected. 18(75%) patients met the Petersen left ventricle non-compaction cardiomyopathy(LVNC) criteria. Patients with NC/C ratio lower than 2.3 had lower LVEDVi and LVESVi (124.9 ± 35.4, 86.4 ± 7.5, p = .003; 86.8 ± 34.6, 52.6 ± 7.6, p = .006), respectively. The median follow-up time was 2129 (IQR [911-2634]) days. The primary endpoint-free 1-year survival was 88.9% (event rate 11.1%), and 5-year survival was 75.7% (event rate 24.3%). CONCLUSION: In a retrospective cohort of PPCM patients, 35.7% of patients' LVEF recovered, and the primary end-point of free-5-year survival was 75%. Twenty-five patients were assessed with CMR; three of four met the Petersen CMR-derived LVNC at initial evaluation.

RESUMO

BACKGROUND: Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients. METHOD AND RESULTS: Forty-three patients with at least 6-month heart transplantation history were included in this study. Each patient had conventional echocardiography and cardiac MRI evaluation, followed by endomyocardial biopsy and right heart catheterization, which were performed in six hours. Echocardiographic parameters of RV systolic function, RV fractional area change (RV FAC), tricuspid annular plane systolic excursion (TAPSE), RV myocardial performance index, and RV global longitudinal strain, were compared with MRI RVEF (P values were <0.001, <0.3, <0.9, and <0.4, respectively). RV FAC was the only parameter to strongly correlate with MRI RVEF (r=0.747, P<0.001); and RV FAC 48.5% value had 90.5% sensitivity and 90.5% specificity to predict the pathologic reference value of MRI RVEF ≤50% (AUC:0.96; 95% CI, 0.908-1.013). CONCLUSION: To our knowledge, this is the first prospective study to evaluate the correlation between the echocardiographic parameters for RV systolic function and MRI RVEF in heart transplantation recipients. RV FAC is the only parameter to correlate well with MRI RVEF, and its routine use in the follow-up of heart transplantation recipients should be considered.

RESUMO

Exposure to high Ca concentrations may influence the development of low-turnover bone disease and coronary artery calcification (CAC) in patients on hemodialysis (HD). In this randomized, controlled study, we investigated the effects of lowering dialysate Ca level on progression of CAC and histologic bone abnormalities in patients on HD. Patients on HD with intact parathyroid hormone levels ≤300 pg/ml receiving dialysate containing 1.75 or 1.50 mmol/L Ca (n=425) were randomized to the 1.25-mmol/L Ca (1.25 Ca; n=212) or the 1.75-mmol/L Ca (1.75 Ca; n=213) dialysate arm. Primary outcome was a change in CAC score measured by multislice computerized tomography; main secondary outcome was a change in bone histomorphometric parameters determined by analysis of bone biopsy specimens. CAC scores increased from 452±869 (mean±SD) in the 1.25 Ca group and 500±909 in the 1.75 Ca group (P=0.68) at baseline to 616±1086 and 803±1412, respectively, at 24 months (P=0.25). Progression rate was significantly lower in the 1.25 Ca group than in the 1.75 Ca group (P=0.03). The prevalence of histologically diagnosed low bone turnover decreased from 85.0% to 41.8% in the 1.25 Ca group (P=0.001) and did not change in the 1.75 Ca group. At 24 months, bone formation rate, trabecular thickness, and bone volume were higher in the 1.25 Ca group than in the 1.75 Ca group. Thus, lowering dialysate Ca levels slowed the progression of CAC and improved bone turnover in patients on HD with baseline intact parathyroid hormone levels ≤300 pg/ml.

RESUMO

BACKGROUND: Knowledge of the normal size of the thoracic aorta and pulmonary arteries is important regarding the detection of the abnormal and valuable in the treatment of patients with congenital and acquired cardiovascular diseases. PURPOSE: To determine the normal diameters of the thoracic vascular structures of pediatric participants on contrast-enhanced multidetector computer tomography (MDCT) scans. MATERIAL AND METHODS: Between July 2010 and July 2014, the MDCT examinations obtained from 520 participants (age range, 0-18 years; mean age, 8.49 years ± 5.54 [standard deviation]; male:female ratio, 1.6:1) with normal cardiovascular examinations were retrospectively evaluated. Patients were divided into six groups according to their age. Diameters of the ascending aorta (AA), descending aorta (DA), main pulmonary artery (MPA), right pulmonary artery (RPA), and left pulmonary artery (LPA) were measured. RESULTS: The diameters of the thoracic vascular structures increased with age and the statistical difference among the age groups and genders were significant. The vascular structures in male patients tended to have higher dimensions than female patients. The LPA demonstrated higher mean values than the RPA in each age group. The mean ratio PA (MPA/AA) is 0.93 ± 0.08 for pediatric participants and it is slightly higher in girls compared to boys (0.93 ± 0.07 and 0.92 ± 0.07, respectively). The level of pulmonary artery bifurcation moves caudally with increasing age with thoracal 6 vertebra being the most common for all age groups (53.3%). CONCLUSION: We believe that the results of our study can serve as a potential reference in differentiating the normal from the abnormal size of the aorta and pulmonary arteries on chest MDCT studies in the pediatric population.

RESUMO

AIM: Our aim was to determine the relationship between erectile dysfunction (ED) and silent coronary artery disease (CAD) by multidetector computed tomography (MDCT) coronary angiography. METHODS: Thirty consecutive men with nonhormonal and nonpsychogenic ED and with no cardiac symptoms were evaluated. Medical history, physical examination and laboratory investigation were performed. The five-item brief form of the International Index of Erectile Function (IIEF-5) was performed for evaluation of ED. The Agatston score (AS) was determined from MDCT images under beta blockade to induce bradycardia. The MDCT coronary angiography findings were evaluated by two radiologists blinded to the clinical findings. Patients were classified into three categories (mild, moderate and severe ED) according to IIEF-5 scores and into five categories (very low, low, moderate, moderately high and high CAD risk) according to the AS. RESULTS: Mean age was 58.3 ± 8.7 years (46-79). 6 patients had hypertriglyceridemia, 4 had hypercholesterolemia and 4 had hyperglycemia. All patients had normal early morning testosterone levels. Regarding IIEF-5 scores, none of them had mild ED, 14 had moderate ED and 16 had severe ED. Of the 14 patients with moderate ED, 21.4% had low and 28.5% had moderate CAD risk regarding AS. Of the 16 patients with severe ED, 25% had moderate, 31.2% had moderately high and 25% had high CAD risk regarding AS. Increasing age was a risk factor for high AS (p = 0.045). There was a significant correlation between AS and ED severity (p = 0.01). CONCLUSIONS: ED and CAD often coexist. MDCT coronary angiography can detect coronary lesions and allow appropriate medical intervention.

RESUMO

Collision tumors in the paranasal region are extremely rare with limited literature data. To the best of our knowledge, this is the first report of associations of squamous cell carcinoma-esthesioneuroblastoma and lymphoma-hemangiopericytoma in the paranasal region. Preoperatively, radiological and clinical findings should be evaluated carefully for the diagnosis and two or more biopsy specimens should be taken from different morphological parts of the lesions. Adjuvant therapy should be planned according to two different histologies and special importance should be given to the tumor which indicates the prognosis of the patient. A multidisciplinary approach is required for the management of synchronous malignancies.

RESUMO

Situs inversus totalis (SIT) describes a complete mirror image of the visceral organs in the thoracic and abdominal cavities. Dextrocardia, in combination with SIT, is a rare congenital anomaly with a frequency of 1:10 000, and coronary heart disease may occur with a similar frequency and manifestation as in the general population. Coronary computed tomography (CT) angiography is useful for accurately assessing the coronary artery origin and position for preprocedural planning of difficult coronary artery catheterisation in SIT. In this case, invasive coronary angiography (ICA) was performed from the same angle but on the opposite side compared to standard angiography. With the use of volume-rendered three-dimensional and curved reformatted images reconstructed from coronary CT angiography, the advancement of guidewires and catheters during ICA as well as the planning of surgical procedures can be performed more safely.

RESUMO

AIMS: Left ventricular non-compaction cardiomyopathy (LVNC) is a poorly understood entity resulting in heart failure. Whether it is a distinct form of cardiomyopathy or an anatomical phenotype is a subject of discussion. The current diagnosis is based on morphologic findings by comparing the compacted to non-compacted myocardium. The study aimed to compare demographic and prognostic variables of patients with dilated cardiomyopathy (DCM) and LVNC. Emphasis was given to cardiac magnetic resonance (CMR) imaging analysis. Data on survival were also assessed. METHODS AND RESULTS: We retrospectively evaluated the characteristics and outcomes of 262 non-ischaemic cardiomyopathy patients with LVNC and DCM phenotypes. Petersen's CMR criteria of non-compacted to the compacted myocardial ratio 2.3 were used to diagnose LVNC. The primary endpoint was a composite endpoint of major adverse cardiovascular events comprising cardiovascular-related death, left ventricular assisted device implantation, or heart transplantation. A total of 262 patients with CMR data were included in the study. One hundred fifty-five patients who fulfilled CMR criteria were diagnosed as LVNC. CMR findings revealed that LVNC patients had higher left ventricular end-diastolic (137.2 ± 51.6, 116.8 ± 44.6, P = 0.002) and systolic volume index (98.4 ± 49.5, 85.9 ± 42.7, P = 0.049). Cardiac haemodynamics, cardiac output (5.61 ± 2.03, 4.96 ± 1.83; P = 0.010), stroke volume (73.9 ± 28.8, 65.1 ± 25.1; P = 0.013), and cardiac index (2.85 ± 1.0, 2.37 ± 0.72; P < 0.0001), were higher in LVNC patients. Of all the 249 patients, 102 (40.9%) patients demonstrated late gadolinium enhancement (LGE). According to Petersen's criteria, the Kaplan-Meier survival outcome did not reveal significant differences (hazard ratio [HR]: 1.53, 95% confidence interval [CI]: [0.89-2.63], P = 0.11). The presence or pattern of LGE did not show significant importance for endpoint-free survival. Most of the sub-epicardial LGE pattern was found in LVNC patients (94.4%). When receiver operator characteristics analysis was applied to NC/C ratio to discriminate the primary endpoint, a higher NC/C ratio of 2.57 was associated with adverse events (HR: 1.90, 95% CI: [1.12-3.24], P = 0.016). CONCLUSIONS: Our study questions the criteria being used for the diagnosis of LVNC. Further evaluation of CMR variables and association of these findings with demographic variables and survival is mandatory.

RESUMO

Stenosis or occlusion of a large right coronary artery or its vein grafts in symptomatic patients who underwent previous bypass grafting procedure with patent left-sided grafts is mostly managed by percutaneous interventions. When percutaneous interventions fail, it is a difficult decision to reoperate on a such patient for a single-vessel disease considering the risk of resternotomy. We present our technique which involves small anterior thoracotomy and partial sternotomy.

RESUMO

Mucormycosis is a rare and often fatal invasive fungal infection. Disseminated or pulmonary forms are common in patients with immune deficiency while rhinocerebral form is common in diabetes mellitus. The aim of this study was to evaluate retrospectively the adult mucormycosis cases which were followed up in our hospital between 2007-2010. The cases were evaluated in terms of demographic characteristics, underlying diseases, laboratory, clinical and treatment results. A total of 12 mucormycosis cases (6 were male; age range: 18-74 years; mean age: 50.83 ± 18.27 years) were evaluated. Ten of the 12 cases had definitive diagnosis of invasive fungal infection according to EORTC/MSG (European Organization for Research and Treatment of Cancer/Mycoses Study Group) criteria whereas two had possible mucormycosis. Six cases had rhinoorbital, four had rhinocerabral, one had pulmonary and one had rhinocerebral and pulmonary mucormycosis. Fever (n= 10; 83%), edema in face (n= 8; 67%) and eyes (n= 6; 50%) were the most common symptoms and findings. Mycologic culture was performed in ten cases and was found positive in five cases (four cases had Rhizopus spp. one case had Mucor). In two cases direct microscopy revealed mycelium but culture did not yield any pathogen. Two cases had concomitant Aspergillus spp. growth. Overall mortality rate was determined as 50% (6/12). All of the cases received antifungal therapy (liposomal amphotericin B and posaconazole or itraconazole), however, surgical intervention was applied to five cases. Mean duration of antifungal treatment was 60.8 ± 47.4 days. Mortality rate was lower in cases who received concomitant surgical therapy, but the difference was not found statistically significant (2/5 vs. 4/7, p> 0.05). Hematologic diseases (n= 6) and diabetes mellitus (n= 3) were the most common underlying diseases in mucormycosis cases. Voriconazole prophylaxis applied to three cases with hematologic diseases was detected as a risk factor. Development of mucormycosis in those cases who were under voriconazole prophylaxis, deserves attention. Since this is the largest 3-years series of adult mucormycosis cases reported from a single center and includes the first cases treated with posaconazole, the results of this evaluation may aid to the management of patients with mucormycosis.

RESUMO

Coronavirus disease 2019 (COVID-19) first emerged in China and rapidly spread in the world causing a pandemic. Chest computed tomography (CT) continues to play an important role in the diagnosis and follow-up of the disease due to shortcomings of the real-time reverse transcription-polymerase chain reaction test, which is the gold standard in the diagnosis of this disease. Typical chest CT findings of COVID-19 pneumonia have been widely reported in the literature. However, atypical findings such as central involvement, peribronchovascular involvement, isolated upper lobe involvement, nodular involvement, lobar consolidation, solitary involvement, pleural and pericardial fluid, and subpleural sparing can also be seen. Knowing these atypical findings is important to avoid misdiagnosis. This review summarizes the atypical findings that can be seen in the course of the disease and may be confused with other diseases.

RESUMO

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported in Wuhan, China. The infection rapidly spread to more than 200 countries around the world. The clinical presentation of the disease may vary from mild illness to severe pneumonia such as acute respiratory distress syndrome (ARDS). The chest computed tomography (CT) has an important complementary role in diagnosis of the disease. The predominant CT findings of the disease are ground glass opacities and consolidations located in subpleural areas of lower lobes. Widespread ground-glass opacities, consolidation, air bronchograms, central involvement of lung parenchyma, mediastinal lymphadenopathy are more common in patients with the severe form of the disease. CT imaging also guides in differentiation of alternative diagnosis or in assessment of associated pulmonary embolism during the course of the disease. In this pictorial review we aim to review the CT features of COVID-19 pneumonia and mention the changes throughout the disease process.

RESUMO

OBJECTIVE: In this study, we aimed to determine the prevalence of gynecomastia by evaluating computed tomography (CT) images of male patients who were admitted to our hospital during the coronavirus disease-2019 (COVID-19) pandemic. MATERIALS AND METHODS: This study included a total of 1,877 patients who underwent chest CT for prediagnosis of COVID-19 pneumonia between March 15th and May 15th, 2020. All images were evaluated for the presence of gynecomastia. Gynecomastia patterns were evaluated according to morphological features, and diagnoses were made by measuring the largest glandular tissue diameter. Statistical analysis was performed with IBM SPSS software version 25.0. RESULTS: The prevalence of gynecomastia was 32.3%. In terms of pattern, 22% were nodular, 57% were dendritic, and 21% were diffuse glandular gynecomastia. A significant correlation was found between age and gynecomastia pattern (p<0.001). The incidence of nodular, dendritic, and diffuse glandular gynecomastia increased with advancing age. A significant difference was found in the analysis of the correlation between age groups and glandular tissue diameters (p<0.001). With an increase in glandular tissue diameter, the gynecomastia pattern changed from a nodular to a diffuse glandular pattern. CONCLUSION: In our study, gynecomastia diagnosis was made through axial CT images. Although CT should not replace mammography and ultrasonography for clinical diagnosis of gynecomastia, chest CT scans can be used to evaluate patients with suspected gynecomastia.

RESUMO

OBJECTIVE: This article focuses on the radiologic findings related to vascular system involvement and pulmonary, pleural, and mediastinal involvement of Behçet disease. CT is an important diagnostic imaging technique in the evaluation of patients with Behçet disease. CONCLUSION: CT is a valuable imaging technique in the diagnostic work-up of Behçet disease. CT effectively demonstrates vascular system involvement that is the main cause of mortality in these patients. CT is also effective in detecting mediastinal, pleural, and pulmonary parenchymal findings related to the disease.

PURPOSE: We aimed to demonstrate the computed tomography (CT) findings observed at the initial presentation of coronavirus disease 2019 (COVID-19) pneumonia and reveal the most frequent infiltration and distribution patterns of the disease. METHODS: One hundred and eighty-five patients (87 men, 98 women; mean age, 48.7 years), who underwent RT-PCR sampling and high-resolution CT examination in our hospital between March 15, 2020, and April 15, 2020, and got a definitive diagnosis of COVID-19 disease via initial or follow-up RT-PCR test, were included in the study. We comprehensively analyzed the most common and relatively rare CT imaging features (e.g., distribution pattern, density of the lesions, additional CT signs) in patients diagnosed with COVID-19 pneumonia. RESULTS: Thirty-eight patients (20.6%) had no evidence of pneumonia on their initial high-resolution CT images. Among 147 patients (79.4%) who had parenchymal infiltration consistent with pneumonia, 10 (6.8%) had a negative baseline RT-PCR test, and positivity was detected as a result of repeated tests. Most of the patients had multifocal (89.1%) and bilateral (86.4%) lesions. The most common location, right lower lobe, was affected in 87.8% of the patients. Lesions were distributed predominantly at peripheral (87.1%) and posterior (46.3%) areas of lung parenchyma. Most of the patients had pure ground glass opacity (GGO) (82.3%) followed by GGO with consolidation (32.7%) and crazy paving pattern (21.8%). Pure consolidation, solid nodules, halo sign, reverse halo sign, vascular enlargement, subpleural line, air-bronchogram, and bronchiectasis were the other findings observed in at least 15% of the cases. Halo sign, acinar nodules, air-bubble sign, pleural thickening and effusion, mediastinal and/or hilar lymphadenopathy were seen rarely (2%-12.9%). Pericardial effusion, pneumothorax, cavitation, and tree-in-bud pattern were not detected in our study group. CONCLUSION: Multifocal and bilateral GGO infiltration predominantly distributed in peripheral, posterior, and lower lung areas was the most common infiltration pattern.

RESUMO

Hydatid disease can occur anywhere in the body and can demonstrate different imaging features that vary according to growth stage, associated complications, and affected tissue. Cardiovascular system involvement of hydatid disease is very rare. In this article, we present the cardiac magnetic resonance (MR) and thorax computed tomography (CT), MR angiography (MRA) findings of hydatid cysts located in the right ventricle and pulmonary arteries after surgical removal of hepatic hydatid cysts.

RESUMO

Herein, an awkward case of globe perforation with a bullet-entering from the right posterior scapular region and leaving the body from the right orbit through the eye - is reported. Route of the bullet could be devastating - as it passed through the neck and the maxillofacial region-however by chance no vital damage occurred. Its path was assessed by plain radiography and computed tomography scans. Sometimes prediction of the trajectory is very difficult without additional radiological investigations. Especially, in the case of any high velocity projectile wounding, physician must be aware of the fact that the bullet's course will not be a linear but most probably a complicated one. Prognosis of the injury depends on the path of the bullet or shrapnel fragment, close clinical observation, an open-minded approach, and the multidisciplinary care. Moreover, even the crime investigation might be needed.

RESUMO

OBJECTIVE: Allograft rejection is still an important cause of morbidity and mortality after heart transplantation (HTx). Many techniques in cardiac magnetic resonance imaging (CMR) were investigated to diagnose acute cellular rejection (ACR). However, there is not enough information about late gadolinium enhancement (LGE) in the myocardium and ACR. METHODS: We prospectively analyzed our consecutive 41 heart transplant recipients who were admitted for routine endomyocardial biopsies. CMR was performed maximum 6 h before the scheduled endomyocardial biopsy. Correlation between LGE in the myocardium and ACR was investigated. RESULTS: Twenty-seven patients showed no rejection, and nine of them had LGE in the myocardium. Fourteen patients had LGE in the left ventricle (LV), and two patients had LGE also in the right ventricle (RV). There was no correlation between LGE and ACR (p=0.879). There was no difference in the left ventricular ejection fraction (LVEF), right ventricular fractional area change (RVFAC), and cardiac ischemic time between the groups (p=0.825, p=0.370, and p=0.419, respectively). LGE in the myocardium could be due to previous rejection episodes; therefore, all patients were retrospectively searched for previous rejection grades and number of episodes. Thirty-eight of the 41 patients had a history of one ACR episode, but none of them had a statistically significant correlation with LGE (for grade 1R, p=0.964 and grade 3R, p=1) There was also no correlation between number of rejection episodes history and LGE. CONCLUSION: LGE is not suitable to detect ACR in heart transplant patients. LGE and the history of ACR have no correlation.
