Abdominal and pelvic CT scan. A mass (arrow) was described as an "agglomerate of venous structures" involving a dilated right iliofemoral axis, but its tumor aetiology was not recognised. A nodule is observed but was reported as "thrombosed collateral circulation in the subcutaneous adipose plane of the ipsilateral inferior quadrant of the abdominal wall" (*). The definitive diagnosis of primary venous leiomyosarcoma was obtained from a biopsy of the nodule.

The presence of tumour was not reported although an increase in maximum diameter of "the thrombosed collateral circulation" of the pelvis and abdominal wall was noted (Figure 1).
Thoracic CT scan. Multiple micronodules are visualized in peripheral topography, more numerous at the right lung, where an 8 mm nodule can be identified in the apical segment of the inferior lobe, with topography and morphology suggestive of metastases.
