Aims and objectives
Common benign disease in the genitourinary tracts can undergo malignant transformation.
On the other hand,
some benign disease may mimic malignancy.
Although the usual imaging features of common benign disease are well known to radiologists,
various unusual imaging features as malignant transformation and benign malignant-mimicking lesions can be particularly misleading; therefore,
both usual and unusual imaging features should always be carefully assessed. The purpose of this presentation is...
Methods and materials
In this presentation,
we describe unusual imaging features: malignant transformation in the genitourinary tracts and benign malignant-mimicking lesions in the genitourinary tracts.
We also correlate imaging features with clinical and pathologic features.
Malignant transformation in the genitourinary tracts - malignant transformation of uterine leiomyoma - malignant transformation of adenomyosis - malignant transformation ofovarian mature cystic teratoma - malignant transformation ofendometriosis Benign malignant-mimicking lesions in the genitourinary tracts - renal angiomyolipoma with minimal fat,
aggressive renal angiomyolipoma with renal vein thrombosis - intravenous leiomyomatosis,
The major teaching points of this exhibit are: It is important to recognize both these malignant transformations and benign malignant-mimicking lesions in the genitourinary tracts. Familiarity with the clinical setting and imaging feature of both these malignant transformations and benign malignant-mimicking lesions in the genitourinary tracts will facilitate prompt and accurate diagnosis and adequate treatment.
