Key result
Magnetic resonance imaging revealed a heterogeneous 6-cm mass with triple sign and post-contrast enhancement, aiding in the diagnosis of primary renal synovial sarcoma.
Case Report (n=1)
This case report highlights the MRI features, including the triple sign, of rare primary renal synovial sarcoma.
Triple sign on MRI may suggest primary renal synovial sarcoma; leaves open validation in prospective series.
Primary renal synovial sarcoma (SS) was first described in 2000 by Argani, with only a few subsequent cases being reported in the English literature. Herein, we describe a case of a 52-year-old woman who presented with right flank pain. Magnetic resonance imaging revealed a 6-cm mass in the lower pole of the right kidney. T1 and T2 weighted imaging revealed a heterogeneous mass with triple sign. There was post-contrast enhancement. Imaging, histology and immunostaining together made the diagnosis of SS of the kidney.
