Tuberous sclerosis can present as retinal tumors in infants, mimicking retinoblastoma. Intracranial imaging is crucial for accurate diagnosis of these retinal hamartomas.

Area of Science:

  • Ophthalmology
  • Neurology
  • Pediatrics

Background:

  • Tuberous sclerosis is a genetic disorder that can affect multiple organs, including the brain and eyes.
  • Retinal manifestations of tuberous sclerosis, such as astrocytic hamartomas, can sometimes be mistaken for retinoblastoma.

Observation:

  • Two infants with tuberous sclerosis initially presented with ophthalmic findings suggestive of retinoblastoma.
  • One infant had small retinal tumors that enlarged over time, accompanied by neurological symptoms.
  • The other infant presented with a large retinal mass and vitreous seeding, also exhibiting intracranial lesions.

Findings:

  • Retinal hamartomas in infants can vary in appearance, from small fleck-like lesions to large, calcified masses.
  • Intracranial subependymal lesions, pathognomic for tuberous sclerosis, were identified via CT and MRI scans in both patients.

  • Neurological findings, including seizures and abnormal EEG, supported the diagnosis in one infant.

    • Implications:

    • Early and accurate diagnosis of tuberous sclerosis is vital to prevent misdiagnosis of retinoblastoma and ensure appropriate management.
    • Ophthalmic examination alone may be insufficient; integration of neuroimaging findings is essential for diagnosing tuberous sclerosis in infants.
    • Understanding the varied presentation of retinal hamartomas aids in differentiating them from other pediatric ocular conditions.
