Hodgkins lymphoma in a patient with mastitis
The patient shown in the images below was a post-partum lactating female who presented for a baseline Ga-67 exam as part of her staging work-up for Hodgkins lymphoma (nodular sclerosing subtype).The planar whole body images demonstrate abnormal uptake of gallium within the patient's primary tumor in the mediastinum (blue arrow). Breast uptake is seen bilaterally (consistent with the patients history of lactation), but is asymmetric- right greater than left (red arrow). Asymmetric breast uptake was concerning for lymphomatous involvement of the breast, but on examination the patient was found to have a right breast mastitis.
Although the SPECT images better demonstrate the distribution of uptake
within the medistinum, they actually improve only contrast resolution (not
spatial resolution)
