Diagnostic Clues and Treatment of Intradural Cranial Chordoma
To the Editor:A 69-year-old man was admitted to our center for poor appetite and malaise for 10 days.Physical examination revealed impaired consciousness and dementia appearance.The head computed tomography (CT) showed a suprasellar lesion of mixed densities without bone invasion,as well as the eggshell calcification presented as interrupted little patches of high-density encircling focus [Figure 1a].The magnetic resonance imaging (MRI) showed an approximately 38.8 mm × 33.1 mm × 36.4 mm lesion in the suprasellar region with an unclear contour and an ampliative third ventricle which was caused by the tumor compression and invasion [Figure 1b-1e].The suprasellar lesion presented isointense on T1-weighted image (WI) [Figure 1b] and hyperintense on T2-WI [Figure lc].The postcontrast lesion was obviously enhanced with cellular nonenhanced region concentrating on center of the tumor [Figure 1d and 1e].It is clear that a lobulated lesion [Figure 1b-1d] along with a honeycomb-like manifestation [Figure 1d and 1e] could be detected in figures.No obvious abnormalities were identified in serological tests of pituitary hormones,adrenocortical hormones,thyroxines,and sex hormones.
