1) A mucocele is a chronic, benign expansile , and cyst-like lesion of the paranasal sinus which contained inspissated secretion and is limited by the mucosa of the affected cavity.

2) A mucocele is an encapsulated fluid collection which occurs due to obstruction of a paranasal sinus ostium.

3) Conclusion : We show here that sphenoid sinus mucocele can simulate a variety of pathological conditions.

4) Results: Retention cyst in 26 cases. mucocele in 4 cases.

5) Methods:186 patients with salivary gland mucocele were randomly divided into two treatment groups, 93 cases in each group, and treated by microwave or surgery respectively.

6) Isolated sphenoid mucocele is rare. It often occurs when the drainage of the sphenoid sinus is obstructed due to inflammation, fibrosis,[http:///mucocele.html] or previous surgery.

7) Frontal sinus mucocele invading the orbit via a traumatic fistula was verified by operative finding and histopathological study.

8) Methods: All 7 patients with mucocele of the appendix were confirmed by pathology and surgery. CT findings were analyzed retrospectively.

9) Objective: To investigate the CT features of mucocele of the appendix, and to improve the diagnostic ability of the disease.

10) Objective To observe the clinical effect of Pingyangmycin on mucocele with local injection.

11) Computed tomography and magnetic resonance imaging revealed paranasal sphenoid sinus mucocele.

12) Conclusion :CT scan is a useful method in diagnosing mucocele of the appendix.

13) ObjectiveTo evaluate the clinical value of lacrimal duct stent for treatment of lacrimal sac mucocele.

14) The tumor also extended to the frontal sinus and sella turcica. Nasal examination showed bulging mucocele from the bilateral ethmoid and sphenoid sinus.

15) ConclusionInterventional procedure using lacrimal duct stent is practicable for the treatment of lacrimal sac mucocele.

16) Pneumoceles may occur suddenly, presumably by a trap-valve mechanism or by rupture of a large mucocele.

17) If possible, it is important to re-establish sinus drainage to prevent mucocele recurrence.

18) Conclusion Microwave therapy is a good method to treat the mucocele in salivary gland. It's easy to practice and has satisfactory effect which is worth applying broadly.

19) Conclusion:Homogenous cystic or soft tissue density and no enhancement or just lightly annular enhancement may be the main characteristic changes on CT in case of appendix mucocele.

20) Objective: To discuss the reason and the treatment method of frontal sinus mucocele caused by neurofibroma of the frontal sinus.
