Awake craniotomy with brain mapping as the routine surgical approach to treating patients with supratentorial intraaxial
tumours: a prospective trial of 200 cases.
In such cases, the tumor cells attain a spindled morphology and may appear different from those in the intraaxial
component; nevertheless, this feature has not been associated with aggressiveness (6,30).
Gamma knife radiosurgery for symptomatic brainstem intraaxial
A hemorrhagic lesion is a contraindication to the t-PA administration; other contraindications arrive if there are signs such as the presence of intraaxial
neoplasm, intracranial neoplasm, arteriovenous malformation, aneurysm, hemorrhagic transformation of an ischemic infarct.
Five of these patients with hyponatremia had the diagnosis of intracranial aneurysm, two had frontobasal tumors (e.g., meningioma and pituitary adenoma), four had intraventricular hematoma, whereas one patient had intraaxial
tumor, one had meningitis, and one had posterior fossa hematoma.
The neuroimaging revealed a large intraaxial
heterogeneous mass lesion in the left frontal and anterior parietal lobe associated with a 1.3 cm right midline shift, effacement of suprasellar cistern, and obliteration of the perimesencephalic cistern likely representing transtentorial descending herniation.
Inclusion criteria for the study were as follows: (1) patients were suspected of having an intraaxial
brain tumor (newly detected or recurrent lesions 6 months or more after successful treatment) by CT and MRI (both were performed as routine clinical studies), (2) each patient gave written informed consent and received MeAIB-PET and MET-PET, and (3) results were confirmed pathologically, or by clinical follow-up more than 6 months after the PET studies.

The CT scan finding shows that 50% cases had intraaxial
lesions and 40% had extraaxial lesions, while 10% had both (Figure 1).
A total of 27 patients (14 males, 13 females; mean age, 51.8 [+ or -] 12.5 years; range, 20-67 years) who each had been diagnosed with an intraaxial
tumor between October 2011 and February 2013 were included in this study.
DWI diffusion sequence: intraaxial
supratentorial, with the emphasis of the left F-T-P-O lobe, showed o large inhomogeneous, franc hyperintense range in the diffusion sequences.
