Chronic hematic cyst of the orbit.

H L Milne, C R Leone, M C Kincaid

    Ophthalmology
    |March 1, 1987
    PubMed
    Summary

    Chronic hematic cysts in the orbit can cause unilateral globe displacement. Computed tomography (CT) findings aid in differentiating these subperiosteal masses from other causes of exophthalmos.

    Area of Science:

    • Ophthalmology
    • Radiology
    • Pathology

    Background:

    • Orbital masses can lead to globe displacement, necessitating accurate diagnosis.
    • Differentiating various orbital pathologies is crucial for appropriate patient management.

    Observation:

    • Four patients presented with chronic hematic cysts causing unilateral globe displacement.
    • Symptoms included painless vertical displacement with onset ranging from 3 weeks to 4 years.
    • Two patients had a history of prior orbital trauma.

    Findings:

    • Computed tomography (CT) revealed homogeneous, nonenhancing, subperiosteal masses in the orbit.
    • Surgical exploration identified masses with a pseudocapsule but no epithelial or endothelial lining.
    • These specific CT and surgical findings are characteristic of chronic hematic cysts.

    Implications:

    • Understanding the clinical presentation and imaging characteristics of orbital hematic cysts is key.
    • CT findings can help distinguish these cysts from other causes of unilateral exophthalmos.
    • This knowledge aids in surgical planning and improves diagnostic accuracy for orbital lesions.
