Subacute bilateral malignant exophthalmos due to orbital medulloblastoma metastases.

A 26-year-old woman complained of subacute bilateral exophthalmos, one year after the extirpation of a cerebellar medulloblastoma. The clinical picture and the orbital computed tomographic scan suggested orbital pseudotumor or endocrine ophthalmopathy rather than orbital medulloblastoma metastases. The latter diagnosis was confirmed by histologic examination. The occurrence of extraneural medulloblastoma metastases including bilateral orbital involvement is discussed.
