Imaging findings
An 18-year-old female presented with cough, fever, and hemoptysis. Initial imaging showed cavitary consolidation, treated as a lung abscess. CT revealed a large consolidation with cavitation, a few nodules, and patchy consolidation in other lung areas. Follow-up imaging showed the cavitary component initially increasing in size before resolving, with other nodules diminishing, leaving a faint hint of the prior cavity.
Key takeaways
This case illustrates an interesting presentation of Granulomatosis with Polyangiitis (GPA) manifesting as mass-like consolidation with cavitation. The patient had a history of recurrent sinusitis and developed renal failure. The cavitary component initially enlarged before responding to steroids and rituximab.
