The development of pneumobilia after blunt trauma.

Pneumobilia is the detection of gas within the biliary system. It usually develops after bilioenteric anastomosis, percutaneous or endoscopic biliary interventions, infections and abscesses. The treatment is surgical, especially in cases with no prior interventions to the biliary system. The development of pneumobilia is quite rare after blunt trauma. Therefore, both the diagnosis and management are challenging for surgeons. Herein, we present the diagnosis and conservative management of a patient with pneumobilia after blunt trauma.

Locations of lesser tuberosity cysts and their association with subscapularis, supraspinatus, and long head of the biceps tendon disorders.

BACKGROUND: Humeral head cysts are not uncommon in individuals with rotator cuff disorders. The cysts are usually considered an indicator of rotator cuff pathologies; however, they may have different meanings in different regions. PURPOSE: To determine the frequency of cysts within and adjacent to the lesser tuberosity and the relationship between these cysts and subscapularis, supraspinatus, and long head of the biceps tendon (LHBT) disorders. MATERIAL AND METHODS: We retrospectively reviewed 760 consecutive shoulder magnetic resonance imaging (MRI) examinations. Among these MRIs, we selected a group of patients with cysts located around the lesser tuberosity. The study population was also divided into two subgroups, patients with cysts within the lesser tuberosity and those with cysts adjacent to the lesser tuberosity. In addition to the number and size of cysts, the MRI appearance of the tendons was evaluated. RESULTS: Eighty-one (10.7%) patients had cysts within and/or adjacent to the lesser tuberosity, 34 (42%) patients had cysts within the lesser tuberosity, and 47 (58%) patients had cysts adjacent to it. LHBT and subscapularis tendon disorders were significantly related to more than one cyst. In a univariate analysis, cysts within the lesser tuberosity were significantly associated with LHBT and subscapularis tendon disorders; however, multivariate analyses showed that only LHBT disorders were significantly associated with cysts within the lesser tuberosity. CONCLUSION: Cysts within the lesser tuberosity were less common than cysts adjacent to it. LHBT and subscapularis tendon disorders were more frequently found in patients with more than one cyst within and/or adjacent to the lesser tuberosity. In addition, cysts within the lesser tuberosity were associated with LHBT disorders.

Frequency and imaging findings of variations in human aortic arch anatomy based on multidetector computed tomography data.

The purpose of this study was to describe the frequency of the variations in the branching pattern of the aortic arch (AA) according to multidetector computed tomography (MDCT) imaging findings. MDCT images of 1136 consecutive patients who had undergone imaging of the chest were retrospectively examined. Eleven different branching patterns were observed. A left-sided AA with three major branches was seen in 74.4% of the patients. Bovine-type AA (21.1%) and independent origin of the left vertebral artery (3.7%) were the next two most common patterns.

Multidetector computed tomography findings of the sternoclavicular joint in patients with rheumatoid arthritis.

We evaluated the multidetector computed tomography (MDCT) findings of the sternoclavicular joint in patients with rheumatoid arthritis (RA) and compare them with general population. Chest MDCT scans of RA patients were reviewed. The control group was formed from age and sex-matched individuals. The most common CT findings were cortical irregularity, joint space narrowing, and osteophytes in study group. There were no statistically significant differences in the MDCT findings between the two groups except that osteophytes were observed more often in the control group. It is difficult to distinguish between the involvement of RA and age-related degenerative changes at the sternoclavicular joint.

Pulmonary involvement in rheumatoid arthritis: multidetector computed tomography findings.

BACKGROUND: Pulmonary involvement in rheumatoid arthritis (RA) is common and encompasses a large spectrum of disease with different treatment options and prognoses. Therefore, assessment of these patients with multidetector computed tomography (MDCT) is vital. PURPOSE: To evaluate the MDCT pulmonary findings of patients with RA and to compare these findings with the clinical status. MATERIAL AND METHODS: Chest MDCT scans of 85 patients with RA between 2006-2012 were assessed. One patient with a pulmonary infection was excluded from the study. MDCT findings and distribution of the CT findings were examined, and patients were classified according to the predominant CT pattern. The pulmonary function test (PFT) results and categories, demographic characteristics, and clinical status of some of the patients for whom the results were obtained were evaluated, and the CT findings, PFT results, demographic characteristics, and clinical status were compared. RESULTS: The study group consisted of 20 men (mean age, 58.1 years ± 13.1; range, 15-77 years) and 64 women (mean age, 55.3 years ± 11.5; range, 30-84 years). The most frequent findings were nodules (78.6%) and pleural thickening (48.8%). The most common CT patterns were follicular bronchiolitis (FB) in 28 (33.3%) patients and nodular disease (ND) in 12 (14.3%) others. There was no statistically significant difference between the CT findings and PFT results, and no statistically significant difference was noted in the CT findings between symptomatic and asymptomatic patients. In addition, there were some patients who exhibited no symptoms and/or had abnormal PFT results but had abnormal CT findings. CONCLUSION: Rheumatoid arthritis is associated with a high frequency of CT findings and CT patterns, with nodules and pleural thickening being the most common CT findings and FB and ND being the most common CT patterns. MDCT identification of patients with RA may be helpful in the evaluation of pulmonary disease, even in patients without symptoms and PFT abnormalities.
