The study was aimed to determine Time Intensity Curve (TIC) type and slope value on Dynamic Contrast Enhancement Magnetic Resonance Imaging (DCE-MRI) examination technique to differentiate between benign and malignant bone lesion. The study was done on December 2018 to July 2019 with retrospective cross sectional analytic study. The samples were bone lesion patients which was examined with Dynamic Contrast Enhancement on 3T MRI. The sample size were 15 subjects, consisted of 8 (53.3%) males and 7 (46.7%) females. The age range of subjects was 13 to 75 years old (38,20 ± 20.49 y.o). Patients with malignant bone lesion were 9 (60%) people and benign bone lesion were 6 (40%) people. DCE-MRI could assess tissue vascularization and perfusion based on TIC. In this study, benign bone lesion showed TIC type 2 and 3, while malignant bone lesion mostly showed TIC type 4, with mean slope value of malignant bone lesion was 83,66 ± 75,34 % and for benign bone lesion was 9,82 ± 5,94 % with cut-off value for malignancy of >26,70%/m. The mean slope value differential for malignant and benign bone lesion was statistically significant (p<0.05). TIC examination had sensitivity of 75% and specificity of 100% in differentiating malignant and benign bone lesion. The difference in pattern type and mean slope value of TIC between benign and malignant bone lesion showed that DCE-MRI has important role in differentiating between benign and malignant bone lesion.

Traumatic lesions of the axillary artery itself are limited to 2.9–9% of major arterial injuries. Pseudoaneurysms represent a pulsating encapsulated hematoma in communication with the lumen of a ruptured vessel. Traumatic pseudoaneurysm of the axillary artery is a rare sequela of injury to the shoulder region. We describe a case of posttraumatic pseudoaneurysm involving the axillary artery, which was initially misdiagnosed as an aggressive soft tissue tumor. The man presented 10 years after an injury from a fall from a tree with a slowly growing mass in the right upper limb region and reduced range of movement. This is a neglected case with a history of traditional massage. The patient presented a pathologic fracture of the right proximal humerus and dislocation of the glenohumeral joint. At the beginning, it was suggested to be a primary soft tissue tumor, but after several examinations, including comparable X-ray, ultrasound, and histopathology, the results did not support a soft tissue tumor. Magnetic resonance imaging and computed tomography angiography (CTA) finally confirmed the finding of a pseudoaneurysm of the right axillary artery associated with a huge hematoma with different age of the bleeding product and granulation tissue. This case demonstrates the necessity of early diagnosis of axillary artery pseudoaneurysm to prevent complications after a history of trauma. CTA is a useful modality to evaluate vascular injury and provides valuable information.
