Small renal masses have historically presented a diagnostic challenge for radiologists and urologists. MRI and CT have a limited capability to differentiate benign and malignant small solid renal masses. The relatively poor negative predictive value of renal biopsy limits the ability to avoid surgical resection in small renal masses with negative biopsy. 99mTc-sestamibi SPECT-CT can be an important tool in directing the management of patients with renal masses.We present the analysis of 99mTc-sestamibi uptake patterns in patients with small renal masses who underwent further characterization of these masses with 99mTc-sestamibi SPECT-CT. Pertinent interpretation points in differentiating renal cell carcinoma from benign renal masses such as oncocytoma or angiomyolipoma with 99mTc-sestamibi SPECT-CT are illustrated via these patient cases.We believe that this exhibit showcases an area in which 99mTc-sestamibi SPECT-CT can significantly aid patient care. The use of this nuclear medicine study in patients with small renal masses will allow clinicians to be more selective when deciding if a renal mass requires excision. The viewer of this exhibit will have a full knowledge of how 99mTc-sestamibi SPECT-CT can be utilized to provide more definite characterization of small solid renal masses.
