Diagnostic Clues and Treatment of Intradural Cranial Chordoma

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 1]a. 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 1]b,[Figure 1]c,[Figure 1]d,[Figure 1]e. The suprasellar lesion presented isointense on T1-weighted image (WI) [Figure 1]b and hyperintense on T2-WI [Figure 1]c. The postcontrast lesion was obviously enhanced with cellular nonenhanced region concentrating on center of the tumor [Figure 1]d and [Figure 1]e. It is clear that a lobulated lesion [Figure 1]b,[Figure 1]c,[Figure 1]d along with a honeycomb-like manifestation [Figure 1]d and [Figure 1]e could be detected in figures. No obvious abnormalities were identified in serological tests of pituitary hormones, adrenocortical hormones, thyroxines, and sex hormones. {Figure 1} Eventually, the patient received the diagnosis of suprasellar tumor inclined to craniopharyngioma before operation. [...]a frontobasal lateral surgical approach for resection was performed. The median age at the time of diagnosis for chordomas is 60 years, with skull base presentations commonly...
