Background:
Sinusitis-derived subperiosteal orbital collection is uncommon and is usually diagnosed as subperiosteal orbital abscess or, rarely, as hematoma. We report a unique and even rarer case of subperiosteal orbital collection, which is actually a complication of hematoma and abscess.
Case Summary:
A 26-year-old female presented with left eyeball pain and ipsilateral chemosis. She had no history of head trauma or upper respiratory infection. Her blood cell count showed an increase in leukocytes. Fiberoptic rhinolaryngoscopy revealed only mucosal edema of the left olfactory crest without apparent discharge. The computed tomography scan results showed an opaque left posterior ethmoid cell with a thickened bony shell and fusiform changes in the periosteal elevation of the medial wall of the left orbit. Emergent surgery revealed an ethmoid mucocele complicated with subperiosteal orbital hematoma and abscess. The pathology of the lamina papyracea between the mucocele and subperiosteal collection was necrotic, and the overlying mucosa was de-epithelialized.
Conclusion:
Subperiosteal orbital hematoma with abscess in a patient with sinusitis adds to the current knowledge of orbital complications of sinusitis.
