Ethmoid mucocele presenting as an orbital mass

Posttravmatik frontoetmoidal mukopiyosel

Paranasal sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal sinuses. Although they are benign in nature, they may result in the destruction of the surrounding bony structures over time. Clinical findings such as exophthalmia, visual impairment, and diplopia occur due to pressure of the fronto-ethmoidal mucocele on the orbita. Currently, the endoscopic intranasal approach is preferred in the treatment of paranasal sinus mucoceles due to its minimal morbidity and low recurrence rates. Here, we present a patient aged 12 years who had a right fronto-ethmoidal mucopyocele secondary to a probable trauma 2 years prior, which resulted in proptosis due to pressure on the orbita.

A nasal mucocele originating from complex facial fractures

Mucoceles are benign, epithelial-lined mucous cysts. Commonly mucoceles form secondary to obstruction of a sinus outflow tract or from mucosal gland entrapment from chronic infection, inflammation, iatrogenic trauma, external trauma, or neoplasm. We present a rare case of a nasal mucocele in a 37-year old male arising from a remote history of maxillofacial trauma. To our knowledge, mucoceles associated with nasal bone fractures have not been reported in the literature.

Giant mucocele originating from the middle concha in a 5-year-old child: a case report

INTRODUCTION

Mucoceles are mucus-filled, epithelial-lined sacs that slowly develop in the paranasal sinuses when sinus or concha bullosa drainage is obstructed by inflammatory processes, trauma, or prior surgery. They are extremely rare in children. Symptoms usually arise from the nasal obstruction or compression of neighboring structures.

CASE PRESENTATION

This case report describes a 5-year-old Turkish boy with a 3-year history of nasal obstruction. A computed tomography scan showed a well-defined soft tissue density lesion, seemingly originating in the region of the middle concha and was suggestive of a middle concha mucocele. The mass was removed by endoscopic sinus surgery.

CONCLUSIONS

In the case of a child presenting with nasal obstruction, mucocele should be remembered in the differential diagnosis of intranasal tumors. Computed tomography and magnetic resonance imaging are helpful in making the diagnosis and endoscopic nasal surgery has proven successful in the treatment.
