Localized swelling, mass and lump, head [R22.0], Reason for Study: ^Reason: eval sellar lesion History: lesion on Head CT Pituitary MRIThere is relatively well circumscribed, homogeneously enhancing, expansile sellar mass with a couple of daughter nodules. The mass is sized about 35.7mm (RL) x 33.6mm (CC: not including daughter nodule) x 33.4mm (AP). The epicenter of the lesion is located slightly on the right side of sellar. The lesion encases right distal ICA from the foramen lacerum segment to paraclinoid segment. Enhancing portion of the tumor involves right cavernous sinus, upper part of clivus, right side of sphenoid sinus and anterior aspect petrous apex.Brain MRI with stealth protocolSellar mass with suprasellar extension was demonstrated. The ventricles, sulci and cisterns are symmetric and unremarkable. The mastoid air cells are clear. Mucosal thickenings are seen on bilateral ethmoid sinuses.
1. Large expansile sellar mass with suprasellar extension. MR evidence of local extension of the mass in particular toward right cavernous sinus with encasing distal right ICA, sphenoid sinus right side, superior aspect of the clivus and right side petrous apex. The size of the mass is measured about 35.7mm (RL) x 33.6mm (CC: not including daughter nodule) x 33.4mm (AP).2. Ventricular system appears to be normal. No other mass is seen.
