title: [Sphenoidal sinus mucocele. Diagnosis and endoscopic surgery].
abstract: Two cases of sphenoid sinus mucocele are described. Diagnosis was based on insidious orbital symptoms, apex orbital syndrome, followed by CT and MRI examinations. In one case the mucocele was preceded by seven years of a successfully treated undifferentiated nasopharyngeal carcinoma. Simple transnasal endoscopic drainage of the mucoceles gave good results, although a monocular blindness of long standing was irreversible. A high level of suspicion, combined with modern imaging techniques and prompt surgical intervention, are the prerequisites for avoiding persisting sequelae.
