“…In the classical Type I emphysematous pyelonephritis, a reduced immune response limits the formation of pus collection and this leads to the spread of the inflammation culminating in a fulminant course of the disease. In contrast, a better immune response in Type II emphysematous pyelonephritis causes formation of pus in the kidney leading to a slower course of the disease and a better prognosis [5, 6]. …”

Presence of air in the kidney can be problematic as the location of the air in different parts of the kidney greatly affects the subsequent management and outcome of the patient. We present here a case of a patient who had emphysematous pyelitis, in which CT scan was able to display presence of air only in the collecting system, thus differentiating this condition from the more fulminant emphysematous pyelonephritis. This leads to a more favourable prognosis and outcome to the patient.

“…The mortality rate for type I EPN or EPN without fluid was 69%, which was significantly higher than 18% for type II EPN or EPN with fluid content (3,4). The first case of type I EPN changing to type II EPN was reported in 1999, and the patient survived after conservative treatment (5). In this paper, we report the first case of gas‐containing liver abscesses converting from total gas content to ones with gas and fluid content.…”
