Patient Data

Age: 75 years
Gender: Female

A large right paraselllar mass is noted measuring up to 18 mm thick, filling the cavernous sinus and moderately narrowing in the transverse portion of the cavernous carotid artery. Anteriorly, the tumour extends for 1 centimetre into the apex of the right orbit, medially into the upper right sphenoid sinus. The tumour grows over the suprasellar region, displacing the posterior pituitary bright spot up and to the left. It contacts the optic chiasm and posteriorly mildly thickens the prepontine dura and anterior right tentorium. Inferiorly, the tumour extends into Meckels cave almost completely filling it.
