Fig. 3From: Primary intracranial neuroendocrine tumor: two case reportsThe radiological results and portraiture of the second patient. a Bone CT scans showed the neoplasm in the anterior cranial fossa eroded the bilateral sphenoid and the ethmoid sinus bone. b T2-weighted MRI showed the lesion was slight hyperintense. c The lesion showed hyperintensity in FLAIR MRI. d–f MRI scans demonstrated the obviously enhancing tumor infiltrated the nasal cavity, and some striped flow-empty action was found on the superior tumor border. g Preoperative picture showed the patient with fat centripetal distribution and pigmentation in the nape. h Postoperative MRI (1 week later) scans showed a gross removal of the intracranial tumor was achieved, but most part of it in the nasal cavity was removedBack to article page
