Sclerosing endophthalmitis in children: computed tomography with histopathologic correlation
Journal of Pediatric Ophthalmology and Strabismus
|September 1, 1983
Summary
Computed tomography (CT) scans revealed diffuse intraocular density in children with sclerosing endophthalmitis, mimicking retinoblastoma. This highlights the challenge in diagnosing leukocoria without advanced imaging techniques.
Area of Science:
- Ophthalmology
- Radiology
- Pediatric Oncology
Background:
- Retinoblastoma is a major cause of leukocoria in children, but other conditions (pseudoglioma) can mimic it, causing diagnostic difficulty.
- Distinguishing retinoblastoma from pseudogliomas is crucial for appropriate management and can be challenging without advanced diagnostic tools.
Observation:
- Orbital computed tomography (CT) was used to study three children with histopathologically diagnosed sclerosing endophthalmitis, presumed secondary to Toxocara canis.
- CT scans showed diffuse increased intraocular density, which was indistinguishable from Coats's disease and non-calcifying retinoblastoma.
Findings:
- Computed tomography (CT) is valuable for detecting intraocular calcification in retinoblastoma and simulating lesions.
- The CT features of sclerosing endophthalmitis, a common pseudoglioma, have not been well-described, leading to potential diagnostic confusion.
Implications:
- CT imaging can aid in assessing the optic nerve and orbit for retinoblastoma therapy planning.
- Further research into CT findings of pseudogliomas like sclerosing endophthalmitis is needed to improve diagnostic accuracy in leukocoria cases.
- Non-invasive tests, including CT, may improve the distinction between retinoblastoma and pseudogliomas, potentially avoiding enucleation.
