She was admitted to our hospital, and brain magnetic resonance imaging (MRI) revealed a right occipital metastatic tumor (Fig. 1).
A: T1-weighted magnetic resonance imaging (MRI) showing disseminated lesions. B: Fluid-attenuated inversion recovery (FLAIR) MRI revealing extensive peritumoral edema in the right temporal and occipital lobes.

Her lungs were clear, but brain MRI revealed a disseminated recurrence in the right occipital region (Fig. 2).
Postoperative computed tomography showing an acute hemorrhage in the left frontal intraparenchyma.

Follow-up CT showed a left frontal intracranial hemorrhage (ICH) away from the operation site (Fig. 3).
A: Preoperative T2-weighted magnetic resonance imaging (MRI) showing massive brain edema with a midline shift. B: T2-weighted MRI performed a month after surgery revealing a decrease in the degree of brain edema and an improvement in the midline shift. It also showed removal of the hematoma in the left frontal lobe.

Postoperative MRI revealed a decrease in the degree of brain edema and an improvement in the midline shift (Fig. 4). 
A: Preoperative magnetic resonance venography (MRV) three-dimensional reconstruction (left lateral view) revealing normal venous drainage. B: Follow-up MRV (left lateral view) taken a month after surgery poorly showing the left frontal veins draining into the superior sagittal sinus.
