Grisel’s syndrome is an uncommon disease following the upper neck inflammatory process or ear, nose, and throat procedure. Clinically, it frequently develops in the pediatric population. The most common initial symptom is acute painful torticollis. This report presents a case of Grisel’s syndrome in an 8-year-old girl after tonsillectomy and adenoidectomy. CT was performed for diagnosis, and the patient was diagnosed with Grisel’s syndrome. Cervical halter traction was performed, and finally the patient recovered successfully without any complication.

Solitary fibrous tumors (SFTs) are spindle-cell tumors that rarely arise within extrathoracic area. Massive SFTs involving the pterygopalatine fossa are extremely rare and surgical excision represents a multidisciplinary surgical challenge. We present a case of 64-year-old female with a huge mass originating from the pterygopalatine fossa invading the skull base. Distinct microscopic findings and a positive nuclear staining of signal transducer and activator of transcription 6 (STAT-6) pathologically confirmed SFT. The right internal maxillary artery branch was embolized preoperatively and a surgical excision was performed through a combined technique of transpalatal, mid-facial degloving and endoscopic approach. Postoperative radiotherapy successfully removed the remnant tumor adjacent to the carvenous sinus. Follow- up MR images showed no evidence of recurrence for two years. To our knowledge, there has been no previous report of the successful treatment of this vast extent of SFT in the pterygopalatine region via endoscopic-external-combined approach and radiotherapy.
