What is the likely diagnosis for a sonogram of the right upper quadrant in a patient with nausea and headaches?

When the right upper quadrant ultrasound reveals a solid mass within the kidney, renal cell carcinoma is the most likely diagnosis. The kidney sits in the RUQ, and RCC is the common malignant solid lesion of the adult kidney. It often presents with non-specific symptoms such as headaches and nausea, which can arise from hypertension or paraneoplastic effects rather than a localized pain. On ultrasound, RCC tends to appear as a solid, irregular renal mass with internal vascularity on Doppler. Hepatoma would imply a liver lesion seen in the liver portion of the RUQ, not a renal mass. A renal abscess usually appears as a complex fluid collection with possible gas and is typically accompanied by fever and elevated white blood cell count. An adrenal hemorrhage would be a mass-like finding above the kidney, associated with different clinical scenarios such as trauma or coagulopathy.
