THE term "orbital pseudotumour" has been used to describe inflammatory lesions of the orbital tissues of unknown aetiology simulating a neoplasm of the orbit.The term is widely accepted by ophthalmologists, little known to neurosurgeons, and puzzling to pathologists.The term is inadequate and, to a certain extent, even misleading.It is inadequate.because it denotes a completely negative approach to this condition.These lesions present a definite clinical entity.The similarity to an orbital neoplasm is only superficial.The name is also misleading because the condition presents itself quite fre- quently as a true tumour, though this is an inflammatory tumefaction and not a neoplastic one.An alternative name for this lesion is "nonspecific granuloma of the orbit".This term, which has found some favour among pathologists (Easton and Smith, 1961), is correct if the word granuloma is used in the ancient, macroscopic way, characterizing a tumefaction not caused by a neoplasm.However, the term granuloma is nowadays used in the microscopic sense to designate an inflammatory reaction characterized by the presence of epithelioid cells and giant cells, and such a histological picture, though occasionally present, is the exception, not the rule.In the absence of any better name and because of the impossibility of using an aetiological designation, the widely-accepted term "inflammatory pseudotumour of the orbit" will probably remain in use.Since the original description and classification...
