Abstract:
Leiomyosarcomas arising directly from the blood vessels are rare. These tumours are formed from the muscular wall of either a major vein or artery. The authors describe the case of an 84-year-old woman with lower back pain with bilateral abdominal irradiation and marked peripheral oedema, who was diagnosed with leiomyosarcoma of the inferior vena cava after biopsy of an infrahepatic mass. An endovascular prosthesis was placed as the patient was proposed for palliative care. Leiomyosarcomas of the inferior vena cava may present with non-specific symptoms. Therefore, the authors aim to draw attention to the diagnosis process, as well as imaging findings related to this pathology.
