A case of pulsating proptosis.

S Davis, J King

    The Medical Journal of Australia
    |March 24, 1979
    PubMed
    Summary

    This case report details a rare instance of unilateral pulsating proptosis caused by a bony orbital defect. This unusual presentation highlights a less common manifestation of neurofibromatosis.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Genetics

    Background:

    • Neurofibromatosis is a genetic disorder characterized by the growth of tumors along nerves.
    • Orbital manifestations of neurofibromatosis can include various tumors and structural abnormalities.
    • Pulsating proptosis, the abnormal protrusion of the eyeball accompanied by a pulse, is a rare clinical sign.

    Observation:

    • A long-term follow-up of a patient with unilateral pulsating proptosis was conducted.
    • The patient presented with clinical signs attributed to a defect in the bony wall of the orbit.
    • This specific orbital bony defect was identified as an unusual manifestation of neurofibromatosis.

    Findings:

    • The pulsating proptosis was directly linked to a congenital or acquired defect in the orbital bone structure.
    • Neurofibromatosis was confirmed as the underlying condition, presenting atypically with this orbital bony defect.
    • The long-term observation allowed for the detailed characterization of the clinical course and stability of the defect.

    Implications:

    • This case expands the understanding of the diverse clinical spectrum of neurofibromatosis.
    • Recognizing bony orbital defects as a potential cause of pulsating proptosis is crucial for accurate diagnosis.
    • Further research into the specific mechanisms linking neurofibromatosis to orbital bone abnormalities may be warranted.
