Primary intracranial synovial sarcoma with hemorrhage: A case report

BACKGROUNDSynovial sarcoma (SS) is a highly malignant tumor of unknown histological origin. This tumor can occur in various parts of the body, including those without synovial structures, but mainly in and around the joints, mostly in the lower extremities. Primary intracranial SSs are remarkably rare. This paper aims to report a case of primary intracranial SS with hemorrhage.CASE SUMMARYA 35-year-old male patient suffered a headache and slurred speech during manual labor and was sent to the emergency department. Through imaging examination, the patient was considered to have high-grade glioma complicated with hemorrhage and was treated with craniotomy. Postoperative pathology revealed SS. positron emission tomography/computed tomography was performed, which ruled out the possibility of metastasis to the intracranial from other parts of the body. Postoperative radiotherapy was given to the patient, during which radiation necrosis occurred. Sixteen months after craniotomy, cranial magnetic resonance imaging revealed recurrence of the tumor.CONCLUSIONPrimary intracranial SS is a rare malignant tumor. Primary intracranial SS with hemorrhage and radiation necrosis should be carefully monitored during postoperative radiotherapy. Surgical resection of the tumor combined with postoperative radiotherapy and chemotherapy is currently used, but the prognosis is poor.     

滑膜肉瘤的二维及彩色多普勒超声特征

目的 探讨滑膜肉瘤的二维及彩色多普勒声像图特征。方法 回顾性分析26例经手术病理证实的滑膜肉瘤患者的超声声像图特征。结果 26例滑膜肉瘤中,17例发生于中青年,二维超声显示均未累及关节腔,表现为弱回声团块,其中20例内部回声不均匀,19例伴液化,7例伴钙化;血流分级：0级5例,Ⅰ级1例,Ⅱ级7例,Ⅲ级13例。15例位于关节旁,与11例非关节旁病灶在深度、最大径、边界、形态、血流信号等方面的差异均无统计学意义（P均>0.05）。20例病变体积较大,与6例体积较小者在病变位置、形态、内部回声及血流信号方面的差异均有统计学意义（P均<0.05）。结论 滑膜肉瘤的超声表现具有一定特征性,有助于提高诊断准确率。

Commentary on "Primary orbital monophasic synovial sarcoma with calcification: A case report"

The present letter to the editor is related to the study titled “Primary orbital monophasic synovial sarcoma with calcification: A case report’’. Orbital synovial sarcoma is one of the rare intraorbital masses seen in adult and pediatric populations. Some case reports in the literature revealed that synovial sarcoma may contain calcifications. Therefore, it is important to make differential diagnosis among calcified orbital masses in childhood.
