Imaging and pathological findings of intramedullary inflammatory pseudotumour in a miniature dachshund: a case report

摘要

Magnetic resonance imaging of the intradural mass lesion. Sagittal T2-weighted images reveal a mass in the dorsal spinal cord at the fourth cervical (C4) level (yellow arrow) and a large hyperintense lesion from C2 to C6 (yellow arrowheads) ( ). The mass is isointense (yellow arrow), and the area around the mass is isointense ( ) on T1-weighted images. The mass is hypo- to isointense (yellow arrow), and the area around the mass is hyperintense on fluid attenuated inversion recovery imaging (yellow arrowheads) ( ). The mass is homogenously enhanced (yellow arrow) after contrast administration and shows a dural tail sign (yellow arrow head) on T1-weighted imaging ( ). The mass (yellow arrows) is spherical and homogenously enhanced after contrast administration on T1-weighted transverse imaging ( )
