    Nasopharyngeal rhabdomyosarcoma can rapidly cause bilateral vision loss in children by spreading to orbital apices. Early high-resolution CT scans are crucial for timely diagnosis of this rare but serious condition.

    Area of Science:

    • Ophthalmology
    • Pediatric Oncology
    • Radiology

    Background:

    • Rhabdomyosarcoma is a common pediatric malignancy.
    • Orbital involvement typically presents unilaterally with proptosis and restricted eye movement.
    • Nasopharyngeal rhabdomyosarcoma is less common but can have aggressive presentations.

    Observation:

    • Two pediatric cases of nasopharyngeal rhabdomyosarcoma presented with rapid, simultaneous bilateral visual loss.
    • Tumor spread to the orbital apices was identified as the cause of visual impairment.
    • Initial computed tomography (CT) scans were misinterpreted, leading to diagnostic delays.

    Findings:

    • Nasopharyngeal rhabdomyosarcoma can metastasize to bilateral orbital apices.
    • Misinterpretation of initial CT scans can significantly delay diagnosis.

  • High-resolution CT is essential for detecting subtle tumor extension.

    • Implications:

    • Emphasizes the need for high-resolution CT scans of the nasopharynx, orbits, and suprasellar region in children with unexplained bilateral visual loss.
    • Highlights the importance of considering nasopharyngeal rhabdomyosarcoma in the differential diagnosis of pediatric vision loss.
    • Underscores the critical role of accurate radiological interpretation in pediatric oncology for prompt treatment initiation.
