Peripapillary Hyperreflective Ovoid Mass-Like Structures as a Finding in Pseudopapilledema in Children

Peripapillary hyperreflective ovoid mass-like structures (PHOMS) can be observed using optical coherence tomography (OCT) of the optic nerve head [1], [2], [3], [4], [5]. The defining morphologic features of PHOMS include (1) a peripapillary location, abutting on the retina, (2) hyperreflectivity on OCT, (3) an ovoid shape on linear OCT scans through the center of the optic disc, and (4) a mass-like space-filling structural characteristic of displacing the adjacent retina from the disc [1], [2], [3], [4], [5]. A vascular complex within the PHOMS can be identified by OCT angiography [6]. PHOMS can be associated with papilledema or pseudopapilledema. Here, we present the case of an 11-year-old female with suspected papilledema.
