Astrocytic hamartoma: a case report

Abstract

A 13-year-old Romanian boy presented to the eye clinic with a chief complaint of blurred distance and near vision. The patient reported a history of a boil on his neck that was removed in Russia one year ago. Cover testing demonstrated bilateral end point nystagmus and exotropia. Ocular health evaluation revealed an astrocytic hamartoma and oculo-rotary nystagmus. Referral to a retinal specialist helped confirm the diagnosis of astrocytic hamartoma but did not elucidate on the possible aetiology of the lesion or rule out tuberous sclerosis as the causative agent, as the patient was lost to follow-up.Based on fundus signs along with the nystagmus, neuro-imaging studies are indicated to rule out any intracranial masses that may be present. The most important differential diagnosis that must excluded is retinoblastoma, which can closely resemble astrocytic hamartoma. The suspicion of tuberous sclerosis was also considered as a potential cause of the retinal lesion, based on clinical signs. The prognosis for astrocytic hamartomas is relatively good, although until tuberous sclerosis is ruled out, caution should be exercised and serial ophthalmic evaluations should continue.

Retinal astrocytic hamartoma in tuberous sclerosis complex in an elderly person: a case report

“…Retinal astrocytic hamartoma (RAH) occurs in 40–50% of patients with TSC [2]. RAH, which is relatively static with little potential for aggressive behaviour, is largely characterised by benign tumours, and astrocyte enlargement and proliferation in the retina [3]. Generally, TSC occurs in children or young patients, and rarely affects the elderly.…”
