Diagnosis: Chemotherapy induced lung gallium uptake
Full history:
The patient has a history of Hodgkin's disease, and is
status post three courses of chemotherapy, most recently
only a few weeks prior to this study. She has
no significant pulmonary symptoms at this time. The
previous gallium scintigraphy demonstrated abdominal
and bone involvement, but no pulmonary involvement.
Findings:
Diffuse pulmonary uptake of gallium is seen, in addition
to normal uptake in bone, lacrimal glands, liver, and spleen.
Discussion:
Diffuse lung involvement could be due to an infectious
process or may be seen following certain forms of
chemotherapy. While it is possible that there is
diffuse involvement with tumor, this is unlikely given
the normal chest radiograph, the lack of previous lung
involvment, and the regression of disease elsewhere
following chemotherapy (as measured by CT examination
and gallium scintigraphy). Given the lack of evidence
of infection (clinically or on radiographs) the
pulmonary uptake is most likely due to the effect of
the chemotherapy.
Followup:
Chest radiographs remain negative for pulmonary involvement.
