Multiple Splenic Infarctions Complicating Granulomatosis with Polyangiitis

Background: A 57-year-old patient was admitted for high-grade fever, asthenia, sweating, dry cough and diffuse arthro-myalgias. Two years earlier, elevated titers of anticytoplasmic antibodies (ANCA) of anti-proteinase 3 specificity and renal biopsy led to a diagnosis of granulomatosis with polyangiitis (GPA) with lung and renal involvement. GPA was treated by steroids, cyclophosphamide and rituximab with subsequent clinical and biological remission. The current chest CT scan was performed for a lung opacity that eventually was proved to be an organising pneumonia. CT also showed an unsuspected pattern of the spleen that was compared with a previous chest CT.
