An association between immune status and chest CT scores in COVID-19 patients.

BACKGROUND: The characteristic features of the immune responses of COVID-19 patients and how they reflect lung involvement have not been clearly elucidated. AIM: The aim of this study was to examine the immune status and the correlations thereof with chest CT scores and lung involvement of patients with COVID-19. METHODS: In this retrospective and single-center study, 72 patients with laboratory-confirmed COVID-19 were recruited. The counts of peripheral lymphocyte subsets (CD3+ T cells, CD4+ T cells, CD8+ T cells, CD19+ B cells and CD16+ 56+ NK cells) and those of serum immunoglobulins (IgA, IgG, IgM) were measured and their associations with chest CT scores analysed. RESULTS: The proportions of lymphopenia in patients with extensive lung involvement were twice that in the general study population. In the severe disease group, the levels of total lymphocytes, T cells, B cells, NK cells; and serum IgA levels, were significantly lower than in the mild disease group (all P < .05). We found that the numbers of lymphocyte subsets and the IgA level negatively correlated with the chest CT scores. On multivariate regression analysis, pretreatment decreases in total lymphocytes, CD3+ T cells, CD4+ T cells, and CD19+ B cells, and serum IgA levels, were independent predictors of severe lung involvement. CONCLUSIONS: The cell numbers of peripheral lymphocyte subsets and the serum IgA level were negatively correlated with the chest CT scores in COVID-19 patients. These parameters tended to independently predict severe lung involvement in such patients.

Paediatric systemic lupus erythematosus: A single referral centre experience.

In this study, the clinical and laboratory findings, management and follow-up of 32 children with paediatric systemic lupus erythematosus (pSLE) were evaluated to determine the prognostic factors in pSLE. Of the 32 patients, 25 (78.1%) were females. Age at onset of symptoms and diagnosis in the patients were 147.6 ± 49 months and 154.3 ± 48 months, respectively. The most common symptom on admission were joint problems, seen in 25 (78.1%) patients. Haematological alterations were seen in 25 (78.1%) cases during follow-up. Lupus nephritis was diagnosed in 10 (31.2%) patients. Malar rash was seen in a total of 12 (37.5%) patients during follow up, however it had been noted in five (15.6%) patients on admission. Antinuclear antibody and anti-dsDNA were positive in all patients and 31 (96.8%) patients, respectively. Decreased complement 3 and 4 levels were noted in 23 (71.8%) patients. Antiphospholipid antibody was studied in 27 patients and it was found to be positive in 13 (48.1%) patients. In conclusion, based on our findings, we would like to emphasize that pSLE has a large and remarkable clinical and laboratory findings.

[Inflammatory myofibroblastic tumor of the lung: histopathology and imaging findings]. / Akcigerin inflamatuvar miyofibroblastik tümörü: histopatoloji ve görüntüleme bulgulari.

Inflammatory myofibroblastic tumor is a neoplasia of unknown clinical etiology that clinically and radiologically tends to mimic a malignant neoplasm. The tumor is histologically composed of a mixture of inflammatory cells, myofibroblastic spindle cells and plasma cells. It can occur in any part of the body. Although pulmonary inflammatory myofibroblastic tumor is the most common primary lung mass especially in childhood, this entity is usually not considered in differential diagnosis of lung nodules or masses. In this article, we aimed to disscus the pathology and imaging findings of the pulmonary inflammatory myofibroblastic tumor and increase the familiarity of radiologists and clinicians to this entity.

Is There A Relation Between Serum Uric Acid Values and Prostatic Calculi Presence?

OBJECTIVE: We planned to examine the connection between serum uric acid (UA) values and prostatic calculi (PCal) presence and to evaluate the relation between PCal and other etiological factors. METHODS: Patients between 20 and 60 years of age who were referred to the clinic with any reason and had non-contrast abdominal tomography (NCACT) for PCal were included in the study. While the patients were separated into 2 groups based on their serum UA level as ≥7 mg/dL (Group 1) and < 7 mg/dL (Group 2), NCACT was also divided into 2 groups as PCal presence (PCal+) and lack (PCal-) serum UA, calcium, phosphorus, sodium, prostate-specific antigen levels and urinary analysis results of the patients were evaluated and compared. RESULTS: PCal were detected in 38 of 169 patients (22%). PCal presence was detected to be significantly high in Group 1 (p = 0.015). While Type A localization PCal were present both in Groups 1 and 2. Based on PCal presence, UA level was detected to be significantly high in PCal+ patients (p = 0.01). No significant difference was detected among the groups in biochemical parameters and urine-related parameters other than UA. CONCLUSION: A significant relation was found between high UA value and PCal in this study. These results may show that UA plays an active role in PCal etiology.

[Imaging of pleural diseases: evaluation of imaging methods based on chest radiography]. / Plevral hastaliklarin görüntülenmesi: Akciger grafisi temelinde görüntüleme yöntemlerinin degerlendirilmesi.

The most commonly employed radiologic method in diagnosis of pleural diseases is conventional chest radiograph. The commonest chest- X-Ray findings are the presence of pleural effusion and thickening. Small pleural effusions are not readily identified on posteroanterior chest radiograph. However, lateral decubitus chest radiograph and chest ultrasonography may show small pleural effusions. These are more efficient methods than posteroanterior chest radiograph in the erect position for demonstrating small amounts of free pleural effusions. Chest ultrasonograph may be able to help in distinguishing the pleural pathologies from parenchymal lesions. On chest radiograph pleural effusions or pleural thickening may obscure the visibility of the underlying disease or parenchymal abnormality. Thus, computed tomography (CT) may provide additional information of determining the extent and severity of pleural disease and may help to differentiate malign pleural lesions from the benign ones. Moreover, CT may provide the differentiation of parenchmal abnormalities from pleural pathologies. CT (coronal and sagittal reformatted images) that also show invasion of chest wall, mediastinum and diaphragm, as well as enlarged hilar or mediastinal lymph nodes. Standart non-invasive imaging techniques may be supplemented with magnetic resonans imaging (MRI).

Magnetic Resonance Imaging May Be a Valuable Radiation-Free Technique for Lung Pathologies in Patients with Primary Immunodeficiency.

PURPOSE: In some primary immunodeficiency (PID) patients, especially in the subgroup with common variable immunodeficiency (CVID), radiosensitivity is a concern and avoidance of repeated radiation exposure has been recommended. To investigate the use of lung Magnetic resonance imaging (MRI) instead of Computed Tomography (CT) for the diagnosis and follow-up of various lesions in the lung parenchyma and airways, especially in PID patients in whom x-ray exposure should be limited. METHODS: The study enrolled 23 patients with PID who underwent thorax CT within the last 3 months and/or who will undergo initial radiological assessment. Lung MRI was performed in all patients to compare the pulmonary findings with CT images. RESULTS: MRI performance was weaker at detecting bronchiectasis extension, and a low concordance was found between MRI and CT in the assessment of the number of bronchial generations. CT better identified peripheral airway abnormalities, while CT and MRI gave similar results for detecting the presence and extension of consolidation, bullae, mucus plugging, bronchial wall thickening, bronchiectasis severity and nodules. CONCLUSIONS: Despite the low spatial resolution, higher cost, and low availability, we suggest MRI as a possible radiation-free alternative to CT in selected patients with PID.

Incidence of retrorenal colon during percutaneous nephrolithotomy.

OBJECTIVE: The aim of this study was to investigate retrorenal colon incidence in percutaneous nephrolithotomy (PNL) interventions made in our clinic. MATERIALS AND METHODS: Clinical data of 804 PNL patients, accumulated over a 7 year period (2006-2012), was surveyed. The patient files were reviewed retrospectively, and only those who had abdominal computed tomography (CT) images before PNL intervention were included in the study. In the CT images, the position of both the ascending and descending colon in relation to the right and left kidneys were evaluated. RESULTS: According to our hospital reports, 394 patients with CT images were included in the present study 27 patients (6.9%) had retrorenal colon, of which 18 (4.6%) were on the left side, 4 (1.0%) on the right side and 5 (1.3%) had bilateral retrorenal colons. Colonic perforation complication was seen only in two patients and the colonic perforation rate was 0.3%. These two cases had no CT images. CONCLUSIONS: PNL, in the process of becoming the standard treatment modality, is a safe and reliable technique for renal stone treatment. Colonic injury should be taken into consideration during PNL interventions of the lower pole of the kidney (especially on the left side) due to the location of retrorenal colon.

[Computed tomography findings in pulmonary involvement of Wegener's granulomatosis: pictorial review]. / Wegener granülomatozis akciger tutulumunda bilgisayarli tomografi bulgulari: resimlerle bir konu.

Wegener's granulomatosis is a necrotising granulomatous vasculitis which has a variable manifestations in the chest that are best described on computed tomography. Imaging findings may include masses or nodules, which may cavitate; consolidations and ground-glass opacities. Wegener's granulomatosis can mimic pneumonia, malignancy, and noninfectious inflammatory diseases. The purpose of this pictorial essay is to demonstrate the characteristic computed tomography findings of pulmonary Wegener's granulomatosis.

Comparison of mammography sensitivity after reduction mammoplasty targeting the glandular and fat tissue.

OBJECTIVE: Mammography may have some limitations in the diagnosis and screening of breast cancer for women who have previously undergone breast reduction surgery. This study aimed to investigate how the structural defects in the breast tissue formed by postoperative changes are reflected on mammography. MATERIAL AND METHODS: The records of patients who had previously undergone breast reduction surgery and who were requested to undergo mammography for breast cancer screening by the general surgery clinic were retrospectively studied. The patients' ages, surgical procedures, postoperative follow-up periods, amount of removed material, and histopathological and mammographic results were studied. The patients were classified into 3 groups: those older than 40 years who underwent reduction mammoplasty targeting predominantly the glandular tissue (group 1), those younger than 40 years who underwent reduction mammoplasty targeting predominantly the fat tissue (group 2), and those older than 40 years who were diagnosed with breast hypertrophy and were not operated (group 3). RESULTS: The mean follow-up period of the patients was 6 (2-10) years. The mean value of resected tissue was 1120 g (680-2070) in group 1 and 1220 g (720-1980) in group 2. The mean age at the time of surgery was 45 (40-70) years for group 1 and 35 (24-40) years for group 2. All patients in group 1 were classified in Breast Imaging-Reporting and Data System (BI-RADS) category 1-2; 28 patients in group 2 were classified in BI-RADS 1-2, 4 were classified in BI-RADS 3, and 8 were classified in BI-RADS 0. In group 3, 35 patients were classified in BI-RADS 1-2, 4 were classified in BI-RADS 3, and 1 was classified in BI-RADS 0. CONCLUSION: We believe that breast reduction surgery targeting predominantly the glandular tissue in patients older than 40 years increases mammographic sensitivity.

Prognostic value of preoperative neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, and multiphasic renal tomography findings in histological subtypes of renal cell carcinoma.

BACKGROUND: To determine the relationship between renal cell carcinoma subtypes and the associated mortality and biochemical parameters. An additional aim was to analyze multiphasic multidetector computed tomography findings. METHODS: This study is a hospital-based retrospective investigation, using 211 patients with a diagnosis of renal cell carcinoma upon computed tomography examination. The histological subtypes included clear cell in 119 patients, chromophobe cell in 30 patients, papillary cell in 25 patients, mixed cell in 32 patients, and sarcomatoid cell in 4 patients. RESULTS: The mean age of the patients participating in this study was 61.18 ± 11.81 years, and the mortality rate was 10.4% (n = 22) through the 2-year follow-up. The ratios of both the neutrophil-to-lymphocyte upon admission to the hospital and platelet-to-lymphocyte of the non-surviving group were significantly higher than those of the surviving group (p < 0.05). When the analysis of the 2-year survival of the patients was examined according to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups (p = 0.01). In two-way analysis of variance test, statistically significant results which were influenced by mortality (p = 0.028) and were found between renal cell carcinoma subtypes in the computed tomography density of corticomedullary phase (p = 0.001). CONCLUSIONS: The neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio may represent widely available biomarkers in renal cell carcinoma, and the logistic regression model indicated that neutrophil-to-lymphocyte ratio was a significant predictor for mortality. According to the median platelet-to-lymphocyte ratio values, the Kaplan-Meier survival curves were significantly different between the surviving and non-surviving groups.

The Comparison of Ultrasound and Tomographic Images of Lung Involvement in Critically Ill Patients With COVID-19 Pneumonia: A Prospective Observational Study.

Introduction Computed tomography (CT) has a high sensitivity for diagnosing COVID-19 pneumonia in critically ill patients, but it has significant limitations. Lung ultrasonography (LUS) is an imaging method increasingly used in intensive care units. Our primary aim is to evaluate the relationship between LUS and CT images by scoring a critically ill patient who was previously diagnosed with COVID-19 pneumonia and underwent CT, as well as to determine their relationship with the patient's oxygenation. Methods This was a single-center, prospective observational study. The study included COVID-19 patients (positive reverse transcription polymerase chain reaction, RT-PCR) who were admitted to the intensive care unit between June 2020 and December 2020, whose oxygen saturation (SpO2) was below 92%, and who underwent a chest tomography scan within the last 12 hours. CT findings were scored by the radiologist using the COVID-19 Reporting and Data System (CO-RADS). The intensivist evaluated 12 regions to determine the LUS score. The ratio of the partial pressure of oxygen in the arterial blood to the inspiratory oxygen concentration (PaO2/FiO2) was used to assess the patient's oxygenation. Results The study included 30 patients and found a weak correlation (ICC = 0.45, 95% CI = 0.25-0.65, p < 0.05) between total scores obtained from LUS and CT scans. The correlation between the total LUS score and oxygenation (r = -0.514, p = 0.004) was stronger than that between the CT score and oxygenation (r = -0.400, p = 0.028). The most common sonographic findings were abnormalities in the pleural line, white lung, and subpleural consolidation. On the other hand, the CT images revealed dense ground-glass opacities and consolidation patterns classified as CO-RADS 5. Conclusion A weak correlation was found between LUS and CT scores in critically ill COVID-19 pneumonia patients. Also, as both scores increased, oxygenation was detected to be impaired, and such a correlation is more evident with the LUS score.

Successful treatment of postinfectious bronchiolitis obliterans with gamma globulin in a tertiary center: 10 years of experience.

INTRODUCTION: Bronchiolitis obliterans is characterized by partial or total occlusion of the bronchioles due to inflammation and fibrosis, and the most common form is postinfectious bronchiolitis obliterans (PIBO). This study aimed to retrospectively present our intravenous immunoglobulin (IVIG) treatment experience in PIBO patients with a clinically severe course despite receiving commonly used treatment protocols. MATERIALS AND METHODS: The study included patients aged 0-18 with subtle immunological abnormalities who were followed up in our center for PIBO between 2010 and 2021. Clinical evaluation, body mass index (BMI), computerized tomography (CT) image scoring, and immunological parameters were recorded before and after IVIG treatment. RESULTS: Of the 11 patients included in the study, 90% were male, the mean age at diagnosis was 27.1 months (range: 5-68 months) and the mean current age was 81.4 months (range: 15-188 months). The number of hospital visits due to infection and the frequency of hospitalizations decreased markedly in the patients who underwent IVIG therapy. Oxygen therapy was discontinued in all patients, and improvements in radiological severity scores were observed. BMI z-scores improved over the baseline values after IVIG therapy. CONCLUSION: Corticosteroids are considered the best first-line treatment to control inflammation in PIBO. In our study group, PIBO patients showed favorable clinical and radiological responses to regular IVIG treatment, possibly due to minor immune deficiency secondary to steroids or as a result of undetected adaptive and innate immune defects involved in the etiology of severe PIBO.

Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study.

PURPOSE: The clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions. METHODS: This retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson's chi-squared test, the Fisher-Freeman-Halton test, and Fisher's exact test were used for the statistical analyses. RESULTS: The overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes. CONCLUSION: ADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision.

Liver Pseudolymphoma (Reactive Lymphoid Hyperplasia): Difficulty in Radiological and Pathological Diagnosis.

BACKGROUND: Pseudolymphoma of the liver (Reactive Lymphoid Hyperplasia) (RLH) is a rare condition. It is usually asymptomatic and detected incidentally on radiological imaging. Imaging features are similar to hepatic adenoma, hepatocellular carcinoma, cholangiocarcinoma, and malignant lymphoma and are not specific for pseudolymphoma of the liver. Percutaneous core biopsy is insufficient to distinguish pseudolymphoma of the liver from low-grade malignant lymphoma and extranodal marginal lymphomas. CASE DESCRIPTIONS: In this article, we present a case of hepatic RLH of a patient who was presented with a skin rash on the leg and was detected incidentally on radiological imaging. CONCLUSION: Preoperative definitive diagnosis of hepatic RLH using various imaging methods, including MRI with hepatocellular agents, is highly difficult.

COVID-19 Pneumonia Presenting with Multiple Nodules Mimicking Metastases: An Atypical Case.

Coronavirus disease 2019 (COVID-19) is an outbreak causing pneumonia due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and computed tomography (CT) images are a significant part of the diagnosis of COVID-19 related pneumonia. Typical chest CT findings are bilateral peripheral ground-glass opacities (GGO) with or without consolidation. Although rare, atypical CT findings have been described, no case of COVID-19 causing multiple solid pulmonary nodules has been reported. In this article, atypical CT findings of a 45-year-old female patient with multiple solid pulmonary nodules mimicking metastasis diagnosed with COVID-19 confirmed by reverse transcription polymerase chain reaction (RT-PCR). Teaching point: COVID-19 pneumonia may mimic multiple metastatic nodules radiologically.

Imaging Features of Breast Plasmacytoma.

Extramedullary plasmacytoma (EMP) occurs as a result of abnormal proliferation of plasma cells outside the bone marrow. Breast plasmacytomas are rare. Radiologically, they can be confused with benign and malignant lesions of the breast. It is important to be able to diagnose EMP in the breast since the treatment strategy is different from that of other lesions and allows for the diagnosis and early treatment of multiple myeloma (MM) relapse. We report imaging and clinicopathological findings of an EMP case in which a 65-year-old patient with MM in remission presented with breast masses.

Liver-Spleen Ratio: Can It Be Used for the Prediction of Coronary Artery Disease?

BACKGROUND: Considering that ectopic fat accumulation in various organs, especially the heart and liver, is a cardiometabolic risk factor, the need for easily accessible markers of ectopic fat accumulation is inevitable. The main starting point of the study is based on the hypothesis of predicting cardiovascular disease risk through the link that can be established between the liver-spleen ratio, which is one of the strong indicators of hepa- tosteatosis, and epicardial adipose tissue volume. METHODS: This was a retrospective study. The records of 283 consecutive patients who underwent coronary computed tomography angiography in our Radiology Department were reviewed retrospectively from our hospital's system. All patients' epicardial adipose tissue volume and liver-spleen ratio were calculated using appropriate criteria on non- contrast computed tomography images. Additionally, the Coronary Artery Disease- Reporting and Data System was calculated on contrast computed tomography images. The participating patients were divided into groups according to the liver-spleen ratio and Coronary Artery Disease-Reporting and Data System score. RESULTS: We found that while there was a negative correlation between the liver-spleen ratio and epicardial adipose tissue volume in the hepatosteatosis group, this relationship was not observed in the non-steatosis group. In addition, we observed that the family his- tory of cardiovascular disease and the frequency of cardiovascular disease were higher in the hepatosteatosis group than in the other group, and there was a correlation between cardiovascular disease and the liver-spleen ratio. Also, we found that age and liver- spleen ratio values were found to be independent predictors of coronary artery disease. CONCLUSION: In our study, we found that the frequency of cardiovascular disease was lower in patients with a high liver-spleen ratio. We also demonstrated in the study that the liver-spleen ratio, which indicates a low level of epicardial adipose tissue volume accumulation, is an independent predictor of cardiovascular disease. In addition, the use of liver-spleen ratio, which is more valuable than liver attenuation in predicting hepatic steatosis, may be more useful in evaluating the risk of hepatosteatosis-related cardio- vascular disease.

Study on the cross-sectional area of the multifidus muscle at the L4-L5 level on ultrasound images of Olympic-style weightlifting and judo athletes.

BACKGROUND: The multifidus muscle is located near the spine and controls the erection of the spine and stabilization during movements of the spine and extremities, and assists in all other spinal movements. Differences in paraspinal muscles between sides and levels, particularly in he multifidus, have been proposed as possible indicators of low back pain or spinal pathology. OBJECTIVE: This study aims to examine the cross-sectional area of the lumbar multifidus muscle at L4-L5 vertebral levels on ultrasound images of athletes in Olympic-style weightlifting, judo athletes and sedentary individuals. METHODS: This study included asymptomatic male athletes (athletes in Olympic-style weightlifting, n= 17, age: 19.24 ± 1.88, judo athletes, n= 17, age: 19.18 ± 1.23) and sedentary individuals (n= 17, age: 19.88 ± 1.31). The cross-sectional area of lumbar multifidus muscles was assessed bilaterally at the L4-L5 segments level in prone and using ultrasound imaging. RESULTS: Lumbar multifidus muscle cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes were larger than those of sedentary individuals (p< 0.004). No asymmetric development was observed in cross-sectional areas of right-left lumbar multifidus muscle at L4-L5 levels of athletes in Olympic-style weightlifting and sedentary individuals (p> 0.008). The cross-sectional areas of the right and left lumbar multifidus muscle at L5 segment of individuals in judo athletes was found to be asymmetrical (p< 0.008). CONCLUSION: Our study shows that the cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes are larger than that of sedentary individuals. The difference in the cross-sectional area of the lumbar multifidus muscle of athlete and sedentary groups might be said to result from hypertrophic effect of trainings of these athletes on the cross-sectional area of the lumbar multifidus muscle.

The determination of the cross-sectional area of the lumbar erector spinae muscles of Olympic style weightlifting athletes by using MRI.

OBJECTIVE: The study aims to measure the cross-sectional area of the lumbar erector spinae muscles from L3-L4 intervertebral disc levels by using magnetic resonance images of Olympic style weightlifting athletes (male n= 15, female n= 15) and sedentary individuals (male n= 15, female n= 15). METHODS: A 1.5 Tesla device was used for the magnetic resonance imaging process of all participants. The images were then executed in ImageJ software and the cross-sectional area was measured after the required synchronization steps were conducted. RESULTS: On the images taken from L3-L4 intervertebral disc levels, we observed that right-left cross-sectional area measurements of erector spinae muscles of sedentary males and females in the control groups were smaller than those of male and female athletes in Olympic style weightlifting. We also found a symmetry between right-left cross-sectional area measurements of groups of athletes. CONCLUSIONS: From the study findings, we might conclude that trainings of Olympic style weightlifting possess a hypertrophic effect on the cross-sectional area of erector spinae muscles of Olympic style weightlifting athletes.

Fracture With Urethral Injury: Evaluation by Retrograde Urethrogram.

Penile fracture is a rare condition. It primarily involves the rupture of the corpus cavernosum during erection, which may also affect the corpus spongiosum and urethra. We describe the case of a 35-year-old man who presented with acute penile pain, penile swelling, and a hematuria after a blunt trauma during sexual intercourse. The emergency retrograde urethrogram revealed a rare condition, extravasation of the opaque material from the penile urethra into the cavernous structure. The partial rupture of the corpus cavernosum with urethral disruption was repaired surgically. At the 3-month postoperative follow-up control, no complications were reported by the patient who has had both normal erectile and voiding functions. In cases of penile fracture with suspected urethral injury, retrograde urethrogram can be used for definitive diagnosis.
