Patient 4. Patient 4. Sinonasal carcinoma t(15;19). A, CT scan demonstrates a midline sinonasal tumor (arrow) with lytic bony destruction of the paranasal sinuses and hard palate (arrowheads). B, Coronal FSEIR MR demonstrates the tumor (arrow), which had a relatively short T2 relaxation time but was hyperintense relative to muscle. C, Sagittal gadolinium-enhanced, fat-suppressed T1-weighted MR image demonstrates enhancing tumor (arrow) extending into the nasopharynx. There is dural enhancement superiorly (arrowheads). C.D.
