Orbital floor abscess secondary to sinusitis in an immunocompromised patient.
A 65-year-old man with a history of renal transplantation presented with facial pain, purulent nasal discharge, and periorbital swelling. Signs of optic nerve compromise developed and persisted despite medial orbital wall decompression. Further imaging revealed an orbital floor abscess secondary to direct communication of a maxillary pseudomonal sinusitis. Full recovery was achieved after further surgical drainage via an endoscopic endonasal approach. Failure to improve after surgical decompression is an indication for repeat imaging. Immunocompromised patients can present atypically. Orbital floor abscess secondary to sinusitis without an underlying odontogenic or traumatic cause has not previously been reported. The authors highlight the importance of clinical vigilance, serial imaging, microbiological investigations, and early surgical intervention in high-risk patients.
