“…Frontal sinus osteomas and mucocoeles are associated in 16% of cases, however, only rarely is the pressure exerted by secretions sufficient to determine delayed erosion of sinus walls [12], meningeal layers and brain parenchyma, as we observed.…”

Life threatening intracranial complications of frontal sinus osteomas: Report of two cases

Paranasal sinuses osteomas are known as biological benign tumours. However, due to the peculiar anatomical relationships, patients harbouring an osteoma within the frontal sinus are exposed to serious orbital and intracranial complications. We report two unusual cases of intracranial mucocoeles associated with frontal osteomas. In one of them, a superposed tension aerocoele required emergency surgery. Although aggressive treatment of asymptomatic osteomas is not warranted, these lesions must be carefully observed and resected as soon as they show clinical and/or radiological signs of progression. The physiopathological and clinical aspects are discussed.

“…In case of the association of paranasal sinus mucocele and osteoma, osteoma is considered to cause the mucocele by occlusion of the sinus ostium. Fenton et al (9) induced mucocele formation in a feline model in experimental conditions. Maturo et al (10) demonstrated the frontal sinus mucocele formation in a goat model, induced by a long-term frontal recess obstruction by frontalis muscle plugging.…”

The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinus due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we described a case of a patient with frontal recess mucocele, associated with contralateral frontal recess osteoma. A 55-year-old man was admitted to the Department of Otorhinolaryngology of our hospital with the complaints of a headache affecting the fronto-ethmoidal region, left-sided nasal obstruction, and postnasal discharge. Computed tomography (CT) scan of the paranasal sinuses showed a dense bony lesion in the left and a cystic hypodense mass in the right-sided frontal recess. The patient was treated surgically, with a combined endoscopicexternal approach, bilaterally. Histopathological examination showed that the wall of the cyst was mucocele, and the bony formation was osteoma. The frontal recess osteoma is regarded as the primary condition. Thus, better ventilation and drainage of the frontal sinus were reestablished.

“…Both of these conditions cause erosion of the frontal bone by stimulating osteoclastic action. 5,6 Small veins located under the basement membrane of the mucosa are valve less, penetrate the posterior wall of the sinus through vascular foramina, and gain access to the subdural space underlying the frontal lobes. This provides a clear avenue for the intracranial spread of infection to the subdural space.…”
