Retinal Astrocytic Hamartomas: Unexpected Findings in a Giant Panda

ثبت نشده
چکیده

We report the unexpected findings of bilateral retinal astrocytic hamartomas in a giant panda. The eyes of Hsing-Hsing, a giant panda that had renal failure, chronic hypertension, degenerative joint disease, and progressive ulcerative keratitis, were examined grossly and histologically. Most of the findings were related to Hsing-Hsing’s debilitated condition or to normal anatomic variations between giant pandas and humans. These f indings included anatomic features typical of a carnivore and metastatic calcification of the cornea and tapetum secondary to renal failure, retinal arteriolar sclerosis and hemorrhage due to hypertension, and bilateral corneal ulcers due to septicemia. Bilateral retinal astrocytic hamartomas were also unexpectedly found. The clinical importance of retinal astrocytic hamartomas is discussed.

Aggressive retinal astrocytomas in four patients with tuberous sclerosis complex.

OBJECTIVE To report the clinical and histopathologic findings of retinal astrocytic tumors that showed progressive growth in four patients with tuberous sclerosis complex (TSC). METHODS Four young children each developed an enlarging retinal neoplasm that eventually necessitated enucleation of the affected eye. The systemic findings, clinical course, and histopathologic findings were reviewed...

Optical coherence tomography visualization of posterior vitreous membrane adhesion in uncomplicated solitary retinal astrocytic hamartoma

Introduction Retinal astrocytic hamartomas are benign tumors of the retinal nerve fiber layer with a characteristic appearance on ophthalmoscopic examination. Although these lesions may be found in isolation without systemic involvement, they usually occur in association with tuberous sclerosis. To our knowledge, there are few reports presenting optical coherence tomography(OCT)findings of vitr...

Bilateral presumed astrocytic hamartomas in a patient with retinitis pigmentosa

Retinal astrocytic hamartomas are benign intraocular tumors classically associated with phacomatoses. Their appearance in isolation is rare. An association between astrocytic hamartomas and retinitis pigmentosa (RP) has been described previously, but controversy still exists regarding the precise nature of these lesions in RP patients. The authors present a case report of a 24-year-old male wit...
