Giant pseudoaneurysm mimicking as soft tissue tumor: a case report

Year: 2026

Type: article

Abstract: Pseudoaneurysms are false aneurysms that develop following arterial wall injury and are characterized by a contained hematoma with turbulent flow. While commonly presenting with typical vascular symptoms, in rare cases, they can mimic soft tissue tumors, especially in chronic post-traumatic settings. We report the case of a 23-year-old male who presented with progressive swelling in the right thigh. Initially suspected to be an aggressive soft tissue malignancy. Chronic pseudoaneurysms may present with features mimicking malignant soft tissue tumors both clinically and radiologically, especially in the absence of classic signs like pulsatility or bruit. magnetic resonance imaging findings, particularly flow artifacts and absence of solid enhancement, and bedside Doppler ultrasound are key diagnostic tools. Misdiagnosis can lead to inappropriate and potentially dangerous interventions.
