A High resolution CT chest taken four months after the onset of symptoms shows extensive multifocal pulmonary nodules and regions of consolidation with areas of cavitation and central bronchiectasis.

Patient had successfully completed systemic corticosteroid and rituximab treatment at the time of imaging
