Worsening of posterior scleritis and orbital pseudotumor in a patient with granulomatosis polyangiitis with rituximab-A case report.

We report a case of exacerbation of posterior scleritis and orbital pseudotumor in a patient with granulomatosis polyangiitis, with initial rituximab infusion. Modifications in rituximab protocols including reduction in maintenance dose for subsequent infusions with increase in premedication dose of intravenous methyl prednisolone may be useful to prevent periinfusional flares. In this case report, we highlight a rare occurrence and modification in rituximab protocol to prevent post-infusional flare of inflammation.
