Diagnosis: Myositis (pectoralis muscles)
Full history:
This patient is a 19 year old man with nodular sclerosing
lymphoma diagnosed eight months prior to this examination.
Prior gallium scintigraphy showed this tumor to be gallium
avid. The patient had undergone chemotherapy and was being
evaluated to determine therapeutic response.
Findings:
Prominent soft tissue uptake is seen in the pectoralis
muscles, bilaterally. Otherwise, the examination
showed only physiologic distribution of activity.
Discussion:
The patient is an avid weight-lifter. Two days prior to the
examination, the patient had an intensive workout, focusing
on his chest muscles. At the time of the examination, he
admitted to being "quite sore" in his chest.
The history and scintigraphic findings are characteristic
of an exercised-induced, myositis.
Followup:
The patient was followed conservatively.
