Wegener's Granulomatosis Presenting as an Orbital Pseudotumor. A Case Report.

A 44-year-old male who complained of left eye pain and double vision consulted our outpatient clinic in July 1996. He was diagnosed as having left orbital pseudotumor 3 years previously. Although steroids and radiotherapy were administered, his ocular symptoms did not remit.A tumorous mass with crust was found in his left nasal cavity. CT findings showed a tumorous legion occupying his left orbita and ethmoid sinus. Microscopic examination of the biopsy specimen from his nasal cavity suggested Wegeners granulomatosis. Cyclophosphamide and prednisolone were administered. The tumor in the nasal cavity and ethmoid sinus shrank and he was discharged in December. Right parapharyngeal mass which was suspected to be recurrence of Wegeners granulomatosis was detected in January 1997. Following re-treatment with cyclophosphamide and prednisolone, a second remission was induced.
