We identified 24 children treated for malignancies between 1962 and 19
92 who had antemortem diagnoses of typhlitis that were confirmed on re
view. The study criteria specified the presence of fever, abdominal pa
in, and tenderness, with radiological evidence of right-sided colonic
inflammation. Typhlitis was most frequent in patients treated for acut
e leukemias. Computed tomography and ultrasonography were more sensiti
ve than plain radiography (false-negative rates, 15%, 23%, and 48%, re
spectively). The wider availability of these sensitive procedures and
the increased intensity of chemotherapeutic regimens may account for a
marked increase in the incidence of typhlitis over the past 5 years.
Most patients responded to aggressive medical management, and typhliti
s was fatal in only two cases (1 of 21 cases managed medically and 1 o
f 3 taken to surgery). Seven patients are alive > 1 year following the
diagnosis. These findings contrast with prior descriptions of typhlit
is as a preterminal event. Computed tomography and/or ultrasonography
should be performed in all neutropenic patients with right-lower-quadr
ant signs to permit prompt diagnosis and treatment.
