F1
Brain magnetic resonance imaging (MRI) revealed a 2-cm isolated tumor with enhancement and obvious perifocal edema over the left frontal lobe [Figure 1].
Microscopically, the metastatic carcinoma shows irregular sheets infiltrating the brain parenchyma. Immunohistochemistry reveals positive nuclear staining for carcinoma cells with anti-GATA3 antibody (x200)

Immunohistochemistry revealed positive nuclear staining for carcinoma cells with anti-GATA3 antibody [Figure 2].
Postoperative magnetic resonance images 3 months (a) and 13 months (b) after the operation reveal focal encephalomalacia in the left frontal lobe with gyral enhancement with no interval variation which favors postoperative change
