Differentiating Benign Notochordal Cell Tumors From Chordomas: Radiographic Features on MRI, CT, and Tomography

Abstract

Radiologic studies may allow distinction of BNCTs from chordomas.

Case Report: An Unusual Osseous Lesion

“…Other symptoms related to the location of the lesion have been reported (coccydynia, limitation of movement, numbness, pain of fingers, neck, buttock and shoulder stiffness) [1]. Radiologically, BNCTs appears hypointense on T1-weighted and hyperintense on T2-weighted MR images [1,3,10,12]. There is no contrast enhancement after injection of gadolinium [10][11][12].…”

“…Radiologically, BNCTs appears hypointense on T1-weighted and hyperintense on T2-weighted MR images [1,3,10,12]. There is no contrast enhancement after injection of gadolinium [10][11][12]. On CT scans the lesions are often sclerotic [10,12].…”

“…There is no contrast enhancement after injection of gadolinium [10][11][12]. On CT scans the lesions are often sclerotic [10,12]. These lesions are well circumscribed.…”

“…Radiologically, chordomas also appear hypointense on T1-weighted and hyperintense on T2-weighted MR images but demonstrate heterogeneous and marked contrast enhancement after injection of gadolinium [3,4,10,12]. There is often extensive lytic bone destruction, presence of an expansive soft tissue mass and intratumoral calcification on CT scans [3,10,12].…”

Intradural chordoma mimicking a lateral sphenoid wing meningioma: a

“…The lesion was highly hyperintense only in T2-weighted images, which raised doubts. Strong hyperintensity on T2-weighted images is typical of chordomas [18]; while, meningiomas are usually isointense or mildly hyperintense.…”
