Findings and procedure details
Cases:
Case 1: A 58-year-old female patient who had a diagnosis of acute myeloid leukemia (AML) presented with a palpable lesion in the right breast. Mediolateral oblique mammogram shows palpable irregular mass (1A). The US shows irregular mass with marked hypoechogenicity and lobulated margins (1B). PET-CT shows increased FDG uptake in the corresponding area (1C). Post-contrast fat saturated T1 weighted MR shows irregularly enhancing lesion (1D). PET-CT also shows increased FDG uptake in the stomach wall compatible with leukemic infiltration (1E). Histopathologic assessment of the lesion revealed as granulocytic sarcoma.
Case 2: A 56-year-old female patient with a known diagnosis of lymphoma underwent PET/CT scan. PET-CT shows increased FDG uptake in the left breast, as well as the left kidney and the ileocecal valve (2F, 2G, 2H respectively). The breast US revealed an irregular heterogenous milimetric lesion in the corresponding area (2A). There is no significant lesion in mediolateral oblique mammogram (2D). The lesion shows diffusion restriction (red arrow) and enhancement (2B-2C and 2E respectively). Histopathologic assessment of the lesion revealed as lymphoma.
Case 3: A 57-year-old female patient with a known diagnosis of malign melanoma presented with a palpable lesion in the left breast. Mediolateral oblique mammogram shows well marginated multiple lesions (3A). The US shows the mass with marked hypoechogenicity and lobulated margins (3B). PET-CT shows increased FDG uptake in the corresponding area as well as in the left lung (3D and 3E). The lesion is also visible on CT scan (3C). Histopathologic assessment of the lesion revealed as metastasis of malign melanoma.
Case 4: A 51-year-old female patient who had a diagnosis of ovarian cancer presented with a palpable lesion in the left breast. Mediolateral oblique mammogram shows a well marginated lesion superimposed to pectoralis muscle (4B). The US shows spherical mass with marked hypoechogenicity and indistinct margins (4A). PET-CT shows increased FDG uptake in the lesion (4C). The lesion was excised (4D), and histopathologic assessment revealed as metastasis of ovarian cancer.
