* Follow-up can be in the form of additional imaging, procedure, or other definitive management.
¶ A pseudotumor is a lesion that can have the appearance of a tumor on ultrasound but can be characterized as a non-tumor structure (eg, column of Bertin, persistent fetal lobulation) by computed tomography or magnetic resonance imaging. Once characterized, pseudotumors do not need additional follow-up.
Δ Solid contrast-enhancing masses need follow-up because some of these can be renal cell carcinomas. Other benign lesions, such as fat-poor angiomyolipoma and oncocytoma, can also have a similar appearance.
◊ Indeterminate lesions include those that are not definitively benign on imaging.Do you want to add Medilib to your home screen?
