Pneumocephalus in frontal sinus osteoma: a case report
1Department of Otolaryngology, Dalhousie University Faculty of Medicine, Halifax Infirmary Hospital, Nova Scotia.
Abstract:
Osteomas are the most commonly encountered neoplasms of the frontal sinus. Extension of these lesions through the posterior table can result in life-threatening complications. We present the case of a 70-year-old man with yellow nail syndrome who complained of persistent rhinorrhea and the sensation of "sloshing" when moving his head. Radiographic investigation revealed a frontal mucocele that had extended to a dramatic intracerebral pneumatocele. This occurred secondary to a frontal sinus osteoma that had been incidentally noted seven years earlier. Surgical exploration via an osteoplastic flap approach allowed us to excise both the osteoma and the associated pneumatomucocele. The resulting dural defect was resurfaced using a flap of pericranium to facilitate anterior cranialization. The features of this interesting case are discussed as an illustration of the potential complications of frontal sinus osteomas. The literature is reviewed regarding management of these lesions and their complications.
Insights
Frontal sinus osteomas, benign tumors, can cause serious intracranial complications. This case highlights a rare instance where an osteoma led to a pneumatocele, emphasizing the need for monitoring and timely intervention.
Area of Science:
- Neurosurgery
- Otolaryngology
- Pathology
Background:
- Frontal sinus osteomas are common benign neoplasms.
- Posterior table extension of these tumors can lead to severe complications.
- Yellow Nail Syndrome is a rare disorder associated with lymphedema and respiratory issues.
Observation:
- A 70-year-old man with Yellow Nail Syndrome presented with rhinorrhea and a "sloshing" sensation.
- Radiographic imaging revealed a frontal mucocele extending into an intracerebral pneumatocele.
- The condition was secondary to a previously noted frontal sinus osteoma.
Findings:
- Surgical excision of the frontal sinus osteoma and associated pneumatomucocele was performed via an osteoplastic flap.
- A pericranial flap was used to repair the dural defect and facilitate anterior cranialization.
- The case illustrates a rare but significant complication of frontal sinus osteomas.
Implications:
- This case underscores the potential for delayed, life-threatening complications from seemingly incidental frontal sinus osteomas.
- Early detection and management of frontal sinus osteomas are crucial to prevent intracranial extension.
- Review of literature provides insights into the management strategies for these lesions and their sequelae.
