Orbital apex cyst: a rare cause of compressive optic neuropathy post-functional endoscopic sinus surgery

Summary: | There are various causes that can lead to compressive optic neuropathy. We present
here orbital apex cyst as an unusual cause of compressive optic neuropathy in a 49-year-old male.
He presented with 2 weeks painless loss of vision in the left eye with left-sided headache. He
had had left functional endoscopic sinus surgery for left nasal polyps 4 years earlier. Magnetic
resonance imaging of brain and orbit revealed a left discrete orbital nodule, possibly orbital cyst
or mucocele, which was compressing on the left optic nerve. Left eye vision improved markedly
from hand movement to 6/36 pinhole 6/18 after initiation of intravenous dexamethasone.
A subsequent endoscopic endonasal left optic nerve decompression found the orbital nodule
lesion to be an orbital cyst. Marsupialization was performed instead of excision, as the cyst
ruptured intraoperatively. Postoperative vision improved to 6/7.5 with normal optic nerve function
postoperatively. Possible cause of orbital apex cyst is discussed. |
