Fig. 3. 42-year-old woman with 2.1-cm right renal mass.

Fig. 3

A, Coronal T2-weighted single-shot fast spin-echo image shows right upper renal mass (arrow), which appears hypointense relative to renal cortex.

B and C, On coronal fat-saturated T1-weighted gradient-echo images acquired during corticomedullary (B) and late nephrographic (C) phases, lesion (arrow) shows intense enhancement and washout, respectively. Lesion was assigned clear cell likelihood score of 2. Because of location of lesion, safe path for percutaneous renal mass biopsy could not be identified. Patient underwent partial nephrectomy; histopathology results and positive homatropine methylbromide 45 immunostaining confirmed angiomyolipoma.
