We present a case of idiopathic intracranial hypertension (IIH) in a 30-year-old woman. The ophthalmoscopic examination revealed marked papilledema in both eyes. Magnetic resonance imaging demonstrated bilateral enlargement of the optic nerve sheath and flattened posterior sclera. Optical coherence tomography demonstrated the presence of peripapillary hyperreflective ovoid mass–like structures (PHOMS). On lumbar puncture, the cerebrospinal fluid pressure was 300 mm H2O. She was prescribed acetazolamide, and the bilateral papilledema gradually improved. Two months later, the papilledema was completely resolved and PHOMS regressed. This case highlights the importance for clinicians to be aware of PHOMS with IIH.
