case_images: (A) Ultrasound showing a hyperechoic cystic-solid tumor of the right kidney measuring 4.8 x 4.0 cm. (B) MRI ADC sequence of renal tumor. (C) MRI DWI sequence of renal tumor. (D) Pathological section: cytoplasmic hyaline in most of the cells, eosinophilic nucleoli in a few cells, and gravel body-like calcifications. (E) TFE3 (Xp11.2) gene breakage detection probe revealing broken TFE3 (the ratio of break signals is 43%, exceeding the threshold of 10%). (F) Lower abdomen CT showing the 29-week fetal morphology. ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging.

case_images: Intrauterine fetal shadow ( Figure 1F ). Several small echoes were detected within this area, suggesting a cystic-solid lesion of the right kidney ( Figure 1A ). Dual renal magnetic resonance (MR) examination scanning confirmed the lesion ( Figures 1B, C ). The FISH test, performed using a transcription factor E3 (TFE3) (Xp11.2) gene break detection probe ( Figures 1D, E ), indicated that the ratio of the TFE3 break signal was 43%, exceeding the threshold value of 10%, which suggests TFE3 breaks had occurred.
