“…The most informative investigation in patients presenting in the manner described above is high resolution CT, which reveals a mass in the maxillary sinus that can simulate malignancy 13 . On CT scan most maxillary sinus mucocoeles are homogenous, isodense with brain and do not enhance with contrast.…”

SUMMARYMucocoeles of the paranasal sinuses most commonly occur in the frontal or anterior ethmoidal sinuses. We report two rare cases of mucocoele of the maxillary sinus and describe the presentation, investigations and treatment. A review of the literature on this rare clinical entity is included, with specific reference to diagnostic imaging to distinguish mucocoeles from neoplastic sinus disease.

“…A mucocoele contains sterile mucus; if the latter becomes infected, a pyocoele is formed. De (1966) described such a case strongly mimicking a carcinoma. A dental abscess would be another diagnosis.…”

Mucocoeles of the maxillary antrum extensie enough to cause local bone destruction appear to be extremely rare. Such a case is reported with the appropriate pathological and radiological findings. Perusal of the literature suggests that this condition, unlike mucocoeles arising in other sinuses, may closely mimic a carcinoma and all authors stress the necessity for Caldwell-Luc surgery to be certain of the diagnosis. Som and Shugar (1980) describe features visible on CT scanning which may help to differentiate between mucocoeles, pyocoeles and carcinomata. In spite of the relatively high incidence of cysts of the antrum, it is thought unlikely that mucocoeles in this location would arise from such a cyst; indeed it is likely that all mucocoeles arise from blockage of the outflow tract of the appropriate sinus. There is a high incidence of maxillary sinus mucocoele in Japan following Caldwell-Luc surgery (Hasegawa et al., 1979). Noyek and Zizmor (1976) suggest that compartmentalization of the autrum after operation may leave islands of mucosa without drainage; such a collection my give rise to a mucocoele.

“…An infected mucocele is called a pyocele or muco-pyocele [1] and it develops more frequently in frontal and anterior ethmoidal sinuses than the posterior ethmoid, sphenoid or maxillary sinuses. The incidence of mucopyocele in general population is 0.4% -0.8% [2] that about only 10% of the mucopyoceles occur in the maxillary sinus [3].…”

Pyocele of maxillary sinus occurs unusually, when its mucocele content gets secondarily infected. Most of the pyocele occupies the frontal and anterior ethmoid sinus involving the frontal-ethmoidal complex expanding into the orbit leading to ocular disorders. Maxillary sinus presentation is rare, and our patient had a well defined loculated pyocele in her right maxillary sinus that we suspected with radiological images and was confirmed by needle aspiration under endoscopic guidance to the pyocele sac. Here we would like to describe more in detail about the nature of the mucopyocele in paranasal sinuses, its presentation and various surgical modalities of treating the pyocele.
