  • Title: [Focal infectious lesions of the renal parenchyma. Comparative contribution of echography and x-ray computed tomography].

    Journal: J Radiol; 1988; 69(8-9):509-16. PubMed ID: 3057184.
    Abstract:
    Nineteen cases of focal infectious lesions of renal parenchyma studied included 10 cases of acute focal bacterial nephritis (AFBN) and 9 of abscess, cases of pyelonephritis without radiological signs being excluded from this report. Each patient had been investigated by intravenous urography (IVU), ultrasound and CT scan imaging. Comparison of value of the different radiological explorations showed that urographic signs were inconstant and only weakly specific, the most valuable examination being CT scan imaging. The latter images show hypodense zones, clearer with contrast, of a rather triangular form and either single or multiple in AFBN, and mainly nodular images in abscess cases. Ultrasound is of intermediate value, being of high performance in cases of abscess but failing to demonstrate AFBN in about half the cases. However, it should not be totally neglected because of its case of access.
