A diagnosis of @entity2883 with @entity2883 (GPA) can be challenging given various clinical manifestations. We report an incident case of GPA presenting with chronic @entity1244 and mimicking an early @entity1997 without renal involvement. A 51 year-old @entity1 with @entity1030 presented with subacute @entity1353 , @entity662 and @entity221 . Physical examination revealed a right nasal mass without discharge or @entity548 . @entity1353 sounds and dullness to percussion were noted at the left lung base. Laboratory findings were significant for @entity491 but normal renal function. The chest CT demonstrated dense consolidation with hypo-enhancement of the lingula. The sinus CT revealed an enhancing mass in the right nasal cavity and anterior ethmoid sinuses with associated bony destruction. @entity1 did not improve with empiric antibiotics for @entity1997 . Aspiration of the lingular fluid showed purulent material, however, microbes did not grow in culture. A positive @entity7134 screen was confirmed. A right nasal biopsy was performed which revealed @entity32 with focal @entity39 and @entity1333 . The final diagnosis was GPA. Given various clinical manifestations, the diagnosis of GPA can be difficult to distinguish from infectious etiologies. This can delay the treatment, which may be life-saving and organ sparing. We emphasize that an initial screening ANCA serology test is recommended in @entity1 with suggestive clinical findings of GPA. Biopsy of an affected organ is paramount for the definitive diagnosis.
