Inflammatory pseudotumour of the paranasal sinuses--a case report.
Inflammatory pseudotumour represents benign non-specific granulation, and is uncommon in the head-and-neck region, particularly in the paranasal sinuses. We present herein the case of a 63-year-old woman with inflammatory pseudotumour of the paranasal sinuses. Physical examination and computed tomography revealed a mass in the bilateral nasal cavity and paranasal sinuses with extension to bilateral orbits. Multiple intranasal biopsies revealed marked lymphoplasmatic infiltration and myofibroblastic proliferation with hyalinisation. Systemic steroid therapy was selected and was very effective. The lesion has shown no evidence of enlargement for more than 1 year. The difficulties in establishing the clinico-pathological diagnosis and treatment are discussed.
