Abstract

Abstract Object To investigate the MR imaging characteristics of intracranial synovial sarcoma by reviewing this case and literature, aiming to improve preoperative diagnostic accuracy for radiologists and neurosurgeons and guide appropriate treatment planning. Material and Methods The clinical and MR images of 1 case with SS in the brain by pathology were retrospectively analyzed, and the causes of misdiagnosis were analyzed Combined with relevant literature. Results MR showed a solid cystic mass in the right frontal lobe, isointense on T1WI, heterogeneous signal on T2WI, Elevated signal on DWI, obvious uneven enhancement on T1WI, and "triple signal sign" and "cobblestone sign" appearance. Conclusion SS in the brain is very rare. MR has certain imaging features, perfect MR examination is helpful for differential diagnosis.
