Angiomyolipoma of the kidney

Angiomyolipoma in the Knee-A Case Report

“…The fat has a characteristic tissue density that often permits easy identification of an angiomyolipoma on CT [12]. Already in 1988, Uhlenbrock et al reported that at MR imaging, most angiomyolipomas could be clearly characterized because of the depiction of intratumoral fat especially by the use of fat-suppression techniques [13]. In the present case, CT and MRI did not reveal fatty component of the 247 fig.…”

Clinical Risk Management in radiology. Part II: applied examples and concluding remarks

“…The suspected diagnosis of a 13-mm angiomyolipoma could have been adequately resolved with an unenhanced CT scan or with an MRI scan. In fact, both techniques are highly accurate in identifying adipose tissue, which in this type of hamartoma is the most prevalent tissue type [6][7][8][9][10][11]. Therefore, both the US and the CT urography studies were inappropriate.…”

“…The term "appropriateness" (in Italian appropriatezza) is becoming familiar to healthcare workers, partly because, in a number of ways, it is one of the key concepts underlying the Italian National Healthcare Plan. The term entered the Italian language from English and encompasses a series of behaviours to be [6][7][8][9][10][11]. Pertanto sia l'ecografia che l'uro-TC non erano indagini appropriate.…”

CT and MR Imaging of Extrahepatic Fatty Masses of the Abdomen and Pelvis: Techniques, Diagnosis, Differential Diagnosis, and Pitfalls

“…Intuitively, the degree of central signal loss can be predicted by the size of the lesion, the section thickness, and the voxel size. MR imaging offers no definite diagnostic advantage over CT (24,25) but should be considered in younger patients because of the absence of ionizing radiation.…”
