Intratumor gas--an ultrasound sign of tumour necrosis.
The ultrasound appearances of primary liver tumour in three patients are described. Changes in these appearances following devascularisation of the tumour by transcatheter embolisation are demonstrated. A possible mechanism for the change in appearances is suggested and is discussed in the light of plain radiographic and computerised tomographic findings.
