Most frequently, a single DVA was observed in the patients. A DVA caput could be located in the deep, subcortical, juxtacortical or deep + subcortical and juxtacortical + subcortical regions. Increasing collecting vein diameter increased visibility on noncontrast MRI, and small DVAs could be overlooked, even with contrast-enhanced MRI series if the images were not examined carefully.

Chronic-contained aortic aneurysm rupture with vertebral erosion is a rare entity with fatal complications. Multidetector computed tomography (CT) angiography is an important diagnostic method for the evaluation of the aortic aneurysms, their complications, and also the relationship between aneurysm and branching vessels and adjacent structures. We present the multidetector CT angiography findings of a 62-year-old patient with chronic-contained thoracoabdominal aortic aneurysm rupture causing severe vertebral body erosion.

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.

Dysplasia epiphysealis hemimelica (DEH) is a rare developmental disorder characterized by osteocartilaginous overgrowth in one or more epiphyses. The disease usually involves a single limb or is hemimelic (lateral or medial compartment), and lower extremities are more frequently affected than upper extremities. Here we present clinical and radiological findings for a male DEH patient at 1.5 and 3.5 years of age. The radiographs obtained at first presentation showed minimal osseous overgrowth and irregularity at the epiphyses around the left knee and ankle joints, respectively. Radiographs obtained at the second presentation showed osteocartilaginous masses at most epiphyses of the left lower extremity. Two months after diagnosis (at 3.7 years old), the patient had surgery on his left knee to relieve increased joint restriction. The histopathological diagnosis was consistent with an osteocartilaginous lesion. This case report presents imaging features and age-related progression of DEH in this patient.

SUMMARYAn enlarged peroneal tubercle can cause a peroneal tendon tear and/or tenosynovitis due to chronic friction. We present the case of a 45-year-old man with tenosynovitis in the peroneus longus and brevis tendons associated with a hypertrophic peroneal tubercle. On admission to our facility, the patient presented with pain while walking and had a fixed mass on the lateral aspect of his right foot. In addition, an osseous prominence corresponding to a hypertrophic peroneal tubercle was seen on the lateral side of the right calcaneus on radiography. MRI confirmed the hypertrophic peroneal tubercle and revealed high-signal intensity within the peroneus longus and brevis tendons along with fluid in their sheaths. BACKGROUND

To determine MRI findings that can differentiate anterior cruciate ligament (ACL) tears from mucoid degeneration. Material and Methods: Thirty-seven patients with complete ACL tears and 43 with ACL mucoid degeneration were included in this study. Discontinuity, the abnormal signal intensity of the ACL on fat-saturated-PD weighted images, contusions, a deep lateral femoral notch, anterior tibial translation, uncovered posterior horn of the lateral meniscus, a celery stalk appearance, thickening, ganglion cysts, intraosseous cysts, the ACL, Blumensaat, and posterior cruciate ligament (PCL) angles were evaluated. Optimum threshold values, sensitivity, specificity, and 95% CIs for the angles were calculated to predict the tear. Results: The prevalence of the significant findings in a tear versus mucoid degeneration, respectively, was as follows: discontinuity (97% vs. 0%, p < 0.001), contusions (65% vs. 2%, p < 0.001), the deep lateral femoral notch (22% vs. 0%, p = 0.001), anterior tibial translation (70% vs. 14%, p < 0.001), uncovered the lateral meniscus (46% vs. 7%, p < 0.001), a celery stalk appearance (0% vs. 66%, p < 0.001), thickening (19% vs. 100%, p < 0.001), ganglion cysts (14% vs. 70%, p < 0.001), and intraosseous cysts (8% vs. 63%, p < 0.001). Threshold values of ACL, Blumensaat, and PCL angles to predict the tear were ≤36° (78% sensitivity, 91% specificity), >11° (84%, 81%), and ≤96° (65%, 91%), respectively. Conclusion: A celery stalk appearance in the mucoid degeneration and discontinuity in an ACL tear are important in the differential diagnosis. ACL, Blumensaat, and PCL angles can be helpful in settings of diagnostic uncertainty.

Our research indicates that vascularity is correlated with breast development in patients with gynecomastia. Additionally, we determined that RI values might be as important as Tanner stages on US.
