Genitourinary tuberculosis is the most common manifestation of extrapulmonary tuberculosis. The epididymides, the seminal vesicles, and the prostate are the most commonly infected sites. The testes are rarely involved. We describe the unusual sonographic findings in a case of tuberculous epididymo-orchitis that presented with multiple small, hypoechoic nodules within the testis.

Small bowel obstruction resulting from the mesodiverticular band is a rare complication of Meckel’s diverticulum and usually presents a diagnostic challenge. We present a case of small bowel obstruction due to the mesodiverticular band of Meckel’s diverticulum with CT scan findings.

Objective: To present the radiological features of blastrelated injuries in the victims of the 10 October 2015 Ankara bombing and emphasize the importance of imaging. Methods: This retrospective descriptive study included a total of 28 patients who underwent CT scan or radiographic imaging within 6 h after the bombing on 10 October 2015. CT scans and plain radiographs were evaluated regarding mechanisms of injuries. Injuries were categorized as primary, secondary, tertiary and quaternary. The number of shrapnel and distribution of injuries were noted. Injury Severity Score (ISS) was used to rank the severity of the injury. Results: Primary blast injuries consisted of only tympanic membrane rupture. A high rate of patients (21/28 patients) in the study group suffered from secondary blast injuries. Tertiary injuries were detected in only three patients. Of the severely injured patients, five had abdominal injuries, three had thoracic injuries and six had extremity injuries. ISS was significantly higher in patients with thoracic and abdominal injuries. Conclusion: Our results after the suicide bomb attacks showed that the most common injury pattern was secondary blast injury. The torso was the most commonly injured body region, followed by the extremities. This specific injury pattern requires the use of immense radiological imaging. Hence, radiologists should be aware of the mechanisms and spectrums of blast-related injuries. Advances in knowledge: Both the unique injury pattern and the following chaos make blast-related injuries a challenge in terms of triage, diagnosis and management. Radiologists should be familiar with the wide spectrum of these unique injuries. INTRODUCTION Mechanisms of injuryThe patterns of blast-related injuries are categorized according to the basic effect of explosion (Table 1). This categorization provides a valuable theoretical framework for understanding blast injuries. However, various mechanisms occur together and victims usually have complicated injuries.1,2 Primary injuries occur secondary to the direct effect of changes in the atmospheric pressure caused by the blast wave, which is an intense over-pressurization impulse created by the explosion. Gas-filled structures such as the middle ear, lung and the gastrointestinal tract are most susceptible. Secondary blast injuries result from flying debris and fragments. They can be seen in any part of the body and are considered to be the most common cause of explosion-related injuries. Fragments would be metallic (shrapnel) or non-metallic. Furthermore, bony fragments from other individuals can be encountered. Tertiary blast injuries occur when the victim body is thrown over by the blast wind producing blunt or penetrating trauma. Quaternary blast injuries are caused by burns, toxic inhalation and exposure to radiation.

Background: Behçet’s disease is a chronic multisystemic vasculitis affecting vessels of differing size in various organs. Thoracic manifestations of disease show wide spectrum involving a variety of anatomic structure within the chest. However, pulmonary artery involvement is a typical manifestation of disease that contributes significantly to mortality in patients. The study aimed to analyze CT features of thoracic manifestations, particularly pulmonary artery involvement, and to quantitatively assess bronchial arteries in Behçet’s disease. Methods: Patients with Behçet’s disease who underwent CT scans for suspected thoracic involvement between 2010 and 2018 were included. CT findings of 52 patients were retrospectively analyzed for thoracic manifestations of the disease. Bronchial arteries were assessed regarding diameter in patients with/without pulmonary artery involvement. The pulmonary symptoms were noted. Results: Of the 52 patients, 67% had thoracic manifestations including pulmonary artery involvement, parenchymal changes, superior vena cava thrombosis, and intracardiac thrombus. Pulmonary artery involvement was observed in 50% of the cohort. Peripheral pulmonary arteries (77%) were the most commonly affected branches, followed by lobar (42%) and central (35%) pulmonary arteries. Other thoracic findings were significantly correlated with pulmonary artery involvement (p<0.05). Compared to patients without pulmonary artery involvement, those with pulmonary artery involvement had a higher bronchial artery diameter (p<0.05) and occurrence rate of dilated bronchial arteries. Conclusion: Involvement of peripheral pulmonary arteries is frequently encountered in Behçet’s disease and it can resemble pulmonary nodules. Dilated bronchial arteries, which can be observed in cases of pulmonary artery involvement, should be considered in patients with hemoptysis.
