Craniopharyngioma simulating bilateral internal ophthalmoplegia

Area of Science:

• Neuro-oncology
• Ophthalmology
• Pediatric Neurology

Background:

• Craniopharyngiomas are rare tumors typically arising from Rathke's pouch remnants.
• They commonly occur in the suprasellar region, potentially compressing adjacent neural structures.
• Ophthalmoplegia, particularly internal ophthalmoplegia, is an infrequent presenting sign for intracranial masses.

Observation:

• A 15-year-old female presented with acute onset of bilateral internal ophthalmoplegia.
• Ophthalmoplegia involves paralysis or weakness of the eye muscles.
• Internal ophthalmoplegia specifically affects the muscles controlling pupillary constriction and accommodation.

Findings:

• Neuroimaging revealed a large craniopharyngioma as the underlying cause.
• The tumor's size and location were implicated in the rapid onset of ophthalmological symptoms.
• This presentation is atypical, as craniopharyngiomas rarely manifest with such prominent and isolated eye movement abnormalities.

Implications:

• This case underscores the importance of considering diverse neurological presentations in the diagnosis of craniopharyngioma.
• It highlights the potential for significant visual and ocular motor deficits secondary to sellar/suprasellar masses.
• Further research may elucidate specific tumor characteristics or mechanisms leading to this unusual ophthalmoplegic presentation.
