case_images: Magnetic resonance imaging scan showed an intramedullary lesion extending from the C5 level to the bulbar region, with hypointense and hyperintense signal in T1- and T2-weighted images, respectively

case_images: T1-weigthed imaging, and without cystic or calcified components [Figure 2]. T2-weighted images showed a heterogeneous hyperintense intramedullary lesion, featuring signs of invasion of the bulbar region; administration of MRI contrast agent showed significant enhancement of the lesion [Figure 3].
case_images: Magnetic resonance imaging scan showed an intramedullary lesion extending from the C5 level to the bulbar region, showing the absence of an adipomatous component in the tumoral lesion and exquisite enhancement with the STIR sequence and after gadolinium administration, respectively

case_images: T1-weigthed imaging, and without cystic or calcified components [Figure 2]. T2-weighted images showed a heterogeneous hyperintense intramedullary lesion, featuring signs of invasion of the bulbar region; administration of MRI contrast agent showed significant enhancement of the lesion [Figure 3]. Use of STIR sequences did not show an adipomatous component of the lesion [Figure 3].
case_images: Histopathological analysis showed a high amount of small cells with loose arrangement, scarce cytoplasm, round hyperchromatic nuclei, and perivascular pseudorosette deposition
