Axial and coronal images using fast spin echo T1 and T2 W images should be obtained with fat-suppressed, postcontrast images using a smaller field of view with a slice thickness of 3 mm. It contains maxillary nerve, the pterygopalatine ganglion, and terminal branches of the internal maxillary artery. Sinonasal tumor extending into the anterior cranial fossa Tumors of the nasal cavity or ethmoid sinus can easily erode the cribriform plate and fovea ethmoidalis to reach the anterior cranial fossa. On T2-weighted imaging, differentiation of tumor from adjacent neural structures is possible. The cavernous sinus forms the superior and medial boundary of the parasagittal compartment while the parapharyngeal and masticator spaces of the suprahyoid neck are along the inferior aspect. The images are reviewed using bone window and soft tissue algorithm. Hemorrhage may be depicted on gradient images.

The relationship of the tumor to the internal carotid, vertebral, and basilar arteries, cavernous sinus, and brainstem determines the operability. Chordoma Skull base chordomas are benign locally invasive neoplasms originating from embryonic remnants of notochord in the basisphenoid and may grow to involve multiple areas of the cranial base, and occasionally erode into the intradural space to encompass neurovascular structures and compress the brainstem.
