5T) or X-ray computed tomography (CT) scans obtained preoperatively and classified according to the criteria proposed by Hardy (13): grade I (microadenomas, <1 cm in diameter), grade II ([greater than or equal to] 1 cm in diameter, intrasellar or with suprasellar extension without causing bony erosion), grade III (locally invasive tumors that may be associated with diffuse sellar enlargement and bony erosion of the sella turcica), and grade IV (invasive tumors that involve extrasellar structures including bone, hypothalamus, and the cavernous sinus).
Noncontrast head CT (Figure 1) demonstrates extensive acute sub-arachnoid hemorrhage involving the suprasellar and right ambient cisterns extending into the anterior hemispheric fissure.
Axial T1WI reveals hypointensity in subcortical white matter and corona radiata of left frontoparietal lobes, Axial T2WI shows hyperintensity in the affected regions, DWI shows restricted diffusion with low ADC values(not shown here), Axial post-contrast T1 FS images reveal gyriform cortical enhancement in the frontoparietal lobes and thickened meningeal enhancement in suprasellar cistern, interpeduncular cistern & bilateral Sylvian fissure cisterns, TOF Angio reveals narrowing in proximal segment of left MCA.
If ipsilateral mesial temporal lobe region and the middle cerebral artery M1 and M2 segments need to be exposed, rotate the head only about 10[degrees]–20[degrees]; for the suprasellar and rear sella lesions, rotate the head about 20[degrees]–40[degrees]; for the anterior skull base midline lesions such as olfactory sulcus meningioma, rotate the head about 40[degrees]–60[degrees].

3 cm with effacement of the suprasellar cistern and mass effect on the brainstem that was consistent with uncal herniation.
Cranial and pituitary magnetic resonance (MR) imaging revealed a mass with a size of approximately 3x3,5x3 cm which filled the base of the sella, obstructed the suprasellar cistern, formed crenation in the base of the third ventricle, compressed the left optic nevre and the optic chiasma on the left with regular borders having the same intensity as the heterogeneous gray matter in the T1A and T2A sequences and contrast enhancement following intravenous injection of contrast material (Figure 2).
Early response to chemotherapy as an indicator for the management of germinoma-like tumours of the pineal and/or suprasellar regions.
Aneurysm rupture and vascular malformation belong to the first form, in which SAH is centered in the central basal or suprasellar cisterns and extends to periphery diffusely [68].
