Initial chest radiograph and computed tomography (CT) images showed multiple satellite nodules in the left lower and upper lobes, and judging from that roentgenographic examination, tuberculosis was the most probable diagnosis (Fig. 1).
Three months later, a new infiltration appears in the left lower lobe and lesions in the left upper and lower lobes improved.

Three months later we rechecked chest radiograph and CT findings, and found new infiltration in the left lower lobe and improvement of lesions in the left upper and lower lobes (Fig. 2).
The colonies develop a rugose appearance, and they take up violet dye from medium after 2 days at 35C.

Cytology was negative but a species of bacteria grew on blood agar media (Fig. 3).
Gram stain shows Gram-negative safety pin shaped organisms (x1,000).

It was Gram-negative, non-spore forming and showed as a safety pin shaped organism on microscopic examination (Fig. 4).
