Unilateral papilledema caused by a fronto-temporo-parietal arachnoid cyst

Am J Ophthalmol. 2001 Oct;132(4):589-91. doi: 10.1016/s0002-9394(01)01043-1.


Purpose: To report a case of unilateral papilledema caused by an arachnoid cyst.

Methods: Interventional case report.

Results: A 36-year-old woman presented with unilateral papilledema in the left eye. Magnetic resonance imaging (MRI) of the brain demonstrated a large fronto-temporo-parietal arachnoid cyst in the left hemisphere. The papilledema resolved after placement of a cysto-peritoneal shunt that drained the cerebrospinal fluid directly from the arachnoid cyst into the peritoneum.

Conclusion: Papilledema caused by increased intracranial pressure is usually bilateral; unilateral papilledema is possible under special anatomical circumstances.
