Clinical question : brain lesion. Signs and symptoms : Same Nonenhanced head CT :Examination demonstrate large area of vasogenic edema in the left cerebellum measuring 28.5 x 36.2-mm in size. There is subtle mass effect on the fourth ventricle.Additional large focus of vasogenic edema in the right inferior frontal lobe measuring 32.6 x 33-mm with evidence of focal mass effect. The findings are highly suspected for peritumoral edema of metastatic lesions and recommend further follow-up with a dedicated pre-and post infused brain MRI.This examination is otherwise unremarkable.Calvarium is intact. Mastoid air cells and middle ear cavities are pneumatized and unremarkable.
1.Two foci of vasogenic edema one in the left cerebellum and a second one in the right inferior frontal lobe concerning for metastatic disease. Recommend further follow-up with pre-and post enhanced brain MRI for better characterization.2.Negative examination otherwise.
