The study highlights the imaging differences between an early incidental and a late symptomatic leiomyosarcoma of the inferior vena cava.
May facilitate earlier recognition of incidental IVC leiomyosarcoma on imaging; hypothesis-generating and should not yet change practice.
Leiomyosarcoma of the inferior vena cava is a rare tumour arising from the smooth muscle fibres of the media with a mean size at diagnosis generally around 12 cm (range 2-38 cm). This study compares a 4-cm leiomyosarcoma of the inferior vena cava discovered incidentally with a symptomatic late stage leiomyosarcoma.
