Orbital psuedotumour with intracranial extension

ABSTRACT

Inflammatory pseudotumour of the orbit is an unusual condition of unknown aetiology which rarely extends beyond the orbit. To our knowledge 19 cases with intracranial extension have been reported, one of which involved the pituitary fossa or sphenoid sinus. Most required cytotoxic agents, surgery or radiotherapy in addition to corticosteroids. We present a case of orbit pseudotumour with extension into the pituitary fossa, sphenoid sinus and cavernous sinuses with vascular compression. Marked clinical improvement occurred on steroid therapy alone.(AU)
