Ophthalmology
Infectious Diseases
Pediatrics

Background:

Cat scratch disease (CSD) is a bacterial infection caused by Bartonella henselae.
Ophthalmic manifestations of CSD are diverse, but optic nerve involvement is uncommon.

Observation:

A 7-year-old boy presented with vision loss in one eye and an optic disc lesion.
Imaging revealed an optic nerve lesion with suspected intracranial extension and a pineal gland nodule.
Histopathology after enucleation confirmed granulomatous inflammation consistent with Bartonella infection.

Findings:

The patient was diagnosed with cat scratch disease presenting as an optic nerve granuloma.
The pineal gland nodule resolved after antibiotic treatment.
Optic nerve granulomas in CSD can be mistaken for retinoblastoma.

Implications:

This case expands the known spectrum of ophthalmic presentations of cat scratch disease.
Early recognition and treatment are crucial to prevent vision loss and misdiagnosis.
Bartonella infection should be considered in pediatric cases of optic nerve lesions and suspected intracranial masses.
