A Rare Case of Neglected Rupture of Right Axillary Artery Pseudoaneurysm Mimicking a Soft Tissue Tumor

We describe a case of posttraumatic pseudoaneurysm i nvolving 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 tr aditional 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, th e 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 c ase 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.Case Rep Oncol 2020;13:1082 –1090
