Previous medical history included colorectal carcinoma with liver metastases, prostatic carcinoma, type 2 DM and arterial hypertension. No focal neurological signs were elicited, and a MRI scan (Figure 1A) showed an extra-axial fronto-basal tumor, with heterogenous contrast enhancement and dural tail sign (not seen in the image). A large cyst between the lesion and the cortex could also be seen. A frontal craniotomy with total excision of a non-infiltrative, dural-adherent mass was performed.engjournal article10.1111/bpa.127071750-3639
