Intracranial extension of paranasal sinus mucocele: Two case reports

Association of Paranasal Sinus Osteoma and Intracranial Mucocele-Two Case Reports-

“…continuity between the frontal sinus and the mucocele, and the aggressiveness of the association. Calcification of intracranial mucoceles is not rare 9,15) and histological evaluation of the bone tissue in mucoceles has been controversial. 10,15) However, histological assessment of the lesions in our cases showed that the mucocele materials contained bone islands (Figs.…”

Mucocele maxilar em lactente de 4 meses de idade

“…The most frequent site is the frontal sinus (60-65%), followed by the ethmoid sinus (20-30%), the maxillary sinuses (10%) and the sphenoidal sinuses (1%). 3 We found no cases of mucoceles in infants aged 4 months -such as the present case -in the medical literature.…”

Frontal Sinus Mucocele With Intracranial Extension Associated With Osteoma in the Anterior Cranial Fossa -Case Report-

“…[1][2][3][5][6][7][10][11][12][13][14][15][16][19][20][21][22] In most cases of coexisting osteoma and paranasal sinus mucocele, the osteoma was considered to be the primary lesion and the mucocele the secondary lesion because osteoma can cause obstruction of sinus drainage leading to mucocele. Growth of mucocele in the paranasal sinus may be prevented by giant osteoma, resulting in intracranial extension of mucocele.…”

“…Only 21 cases have been reported previously. 1,3,[5][6][7][10][11][12][13][14][15][16][19][20][21][22] Paranasal sinus osteoma can protrude into the anterior cranial fossa and cause intracranial mucocele, as well as cerebrospinal fluid (CSF) leakage and pneumocephalus. 6,7,19,20) We describe a rare case of a giant intracranial mucocele associated with a paranasal sinus osteoma in a patient who presented with a generalized convulsion, discuss a hypothesis for the pathogenesis of the association, and the appropriate surgical strategy for co-existing lesions.…”
