Primary Brain Tumor And Homonymous Hemianopsia - Head MRI With Contrast

This video presents head MRI with contrast enhancement in a patient presenting right homonymous hemianopsia with normal carotid duplex.

Technique: multiplanar, multisequence MR images of the brain without and with 7 mL of gadavist for intravenous contrast enhancement.

Impression:
1. 8.6 cm left temporal lobe lesion with vasogenic edema and 3 mm midline shift, likely represent primary brain cancer. Due to contrast enhancement is more prominent in the posterior and medial aspect of the lesion.
2. The left-sided optic tract and the optic radiation traversed through this region of signal abnormality, likely affected by this lesion and explaining patient's right-sided homonymous hemianopsia.
