[Post-radiation mucocele in two @entity1 treated for XXXX ].

@entity1 @entity5 @entity189 @entity892 @entity10
A 30-year-old @entity1 , with a history of @entity189 , which was treated by radiotherapy nine years previously, presented with occasional @entity892 and @entity10 . A nasopharyngeal biopsy showed no recurrence. The imaging revealed a sphenoidal sinus mucocele. Endoscopic marsupialization of the mucocele allowed clinical improvement. A 56-year-old @entity1 presented, five years after radiotherapy for @entity189 , with a fronto-orbital mass. CT-scan revealed a fronto-ethmoidal mucocele. Nasopharyngeal biopsy showed @entity5 recurrence. Marsupialization of mucocele was performed. Recurrence of the @entity189 was treated by radiotherapy and chemotherapy. Sphenoidal sinus mucocele developing after radiotherapy for @entity189 has rarely been reported. CT scan and MRI are useful tools in making the diagnosis. Biopsy is required to diagnose recurrence or associated radio-induced @entity5 . Endoscopic approach gives good results.
