title: Rare choroidal tumour simulating a malignant melanoma.
abstract: A 15-year-old boy had been treated for a central chorioretinitis of his right eye. The other eye had always been normal. Two years later he presented a relapse with deterioration of central visual acuity. All clinical tests, including fluorescein angiography, suggested an inflammatory process this time again. Thereafter, the patient did not show up for 6 years. Then he came to hospital because of strong pains in his right eye. Now, a blind and inflamed eye was found with a huge tumour from the optic nerve extending to the temporal periphery. All clinical investigations, amongst others ultrasonography, computerized tomography and magnetic resonance tomography, suggested a choroidal melanoma with extrabulbar extension. An enucleation with partial exenteration was performed. A demonstration and discussion of the clinical findings and the rare and complicated histological diagnosis of a very unusual ectopic meningioma-like lesion are given.
