Summary

Persistent hyperplastic primary vitreous (PHPV) is a congenital eye condition. MRI can help differentiate dorsal PHPV from retinoblastoma, crucial for appropriate treatment.

Background:

Persistent hyperplastic primary vitreous (PHPV) is a congenital anomaly resulting from the failure of the primary vitreous and its associated hyaloid vasculature to regress.
Leukocoria, a white pupillary reflex, is a key clinical sign that necessitates prompt and accurate diagnosis.

Observation:

This study focuses on the dorsal type of PHPV.
Magnetic Resonance Imaging (MRI) is utilized to visualize the ocular structures and identify characteristic features of dorsal PHPV.

Findings:

MRI demonstrates specific features of dorsal PHPV that aid in its identification.
These features are distinct from those of other leukocoria causes, particularly retinoblastoma.

Implications:

Accurate MRI-based diagnosis of dorsal PHPV is critical for appropriate clinical management.
Distinguishing PHPV from retinoblastoma avoids unnecessary and potentially harmful treatments for a benign condition and ensures timely intervention for malignant conditions.
