Visual dysfunction: Abnormal sign of benign spheno-ethmoidal lesions

Isolated visual dysfunction with or without proptosis is rarely described as a sign of benign sphenoethmoidal lesions. Five patients with benign swelling of the sino-orbital region and related visual defects are reported. Cases include one patient with fibrous dysplasia, two patients with mucocoeles and two patients suffering from aspergillosis of the sinuses. A review of the literature and discussion of the cases is presented.
