title: Forme fruste of von Recklinghausen's disease: unilateral association of an orbital neurofibroma, a trigeminal neurinoma, and an acoustic neurinoma. Case Report.
abstract: A patient who presented with a tumor of the left ambient cistern, a left cerebellopontine angle tumor, and a left orbital tumor causing left hearing loss and left exophthalmos without café au lait spots or cutaneous neurofibromas is described. There was no family history of von Recklinghausen's disease. A cerebellopontine angle tumor removed by a suboccipital craniectomy was an acoustic neurinoma. An ambient cistern tumor was approached through a subtemporal route. A tumor arising from the trigeminal nerve was also a neurinoma. An orbital neurofibroma was excised by a frontal craniotomy with removal of the orbital roof. This rare unilateral association of neurinomas and a neurofibroma on the left side was thought to be a forme fruste of von Recklinghausen's disease, and it could be considered a presentation of a mosaic of von Recklinghausen's disease.
