Renal schwannoma: A case report and literature review of a rare and benign entity mimicking an invasive renal neoplasm.

Schwannomas of the kidney are rare with only a handful of cases reported in literature. We present a case of a large Schwannoma of the right kidney causing mass effect with imaging characteristics thought to represent renal cell carcinoma. On imaging, these masses present similarly to solid renal masses and are therefore indistinguishable without tissue diagnosis. Thus, surgical resection is the definitive treatment for renal schwannomas.
