title: Localised Wegener's granulomatosis presenting as an orbital pseudotumour with extension into the posterior cranial fossa.
abstract: Pseudotumour has rarely been reported to invade the intracranial cavity. We present a case of pseudotumour which extended intra-cranially into the posterior cranial fossa. The patient had circulating antineutrophil cytoplasmic antibodies in titres diagnostic for Wegener's granulomatosis. In the absence of clinical renal or respiratory tract disease, the case may represent a newly recognized sub-type of "localised" Wegener's granulomatosis.
