CTICasesPneumonic Tularemia from Rabbit Carcass Exposure

Imaging findings
A man presented with fever and cough after a hunting trip where his friends skinned rabbits. A chest radiograph initially showed subtle consolidation, which progressed to more dramatic consolidation and accompanying pleural effusion a few days later. CT demonstrated a compact, round pneumonia in the left upper lobe with a posterior pleural effusion.
Key takeaways
This case illustrates pneumonic tularemia (caused by Francisella tularensis), likely acquired through exposure to infected rabbit carcasses. The imaging findings of round pneumonia and pleural effusion are notable. The pneumonic form is less common than the ulceroglandular type, and its diagnosis requires high suspicion, especially in at-risk individuals, with special precautions needed for laboratory handling.
