Importance of MRI in the diagnosis of a rare intracranial mucocele associated with frontal paranasal osteoma: Case report and literature review
Osteomas and cystic mucoceles are well-known benign tumors, affecting the paranasal sinuses. However, the concomitant presence of both lesions represents a rare occurrence, with only a handful of reported cases. We report a case of a frontal sinus osteoma associated with an intracranial mucocele, in...

Zusammenfassung: | Osteomas and cystic mucoceles are well-known benign tumors, affecting the paranasal sinuses. However, the concomitant presence of both lesions represents a rare occurrence, with only a handful of reported cases. We report a case of a frontal sinus osteoma associated with an intracranial mucocele, in a 61-year-old male patient, with a 3-month history of intermittent headaches and subsequent generalized seizures. Post-contrast MRI showed a frontal heterogeneously enhanced lesion with an adjacent non-enhanced cyst. After surgical excision, histopathological examination established the diagnosis of osteoma with mucoid cyst. Mucoceles increase in size progressively and gradually. They are mostly asymptomatic, nevertheless, once they extend intracranially, complications like infections, seizures, or other neurological disturbances, may frequently occur, indicating the necessity for surgical treatment. Imaging modalities, in particular a head MRI is paramount while contemplating the differential diagnosis of a solid and cystic intracranial lesions, owing to its high sensitivity and specificity. The aim of this case report is to underscore the importance of considering intracranial mucoceles in the differential diagnosis of cystic lesions in the anterior cranial fossa when associated with a solid, possibly obstructing mass. |
