Differentials Spine

Question 1

Intramedullary Spinal lesions

Answer 1

Astrocytoma
Ependymoma
Haemangioblastoma
Metastasis
Demyelinating lesion
Inflammatory process
Infection
Vascular lesion
Syrinx
Traumatic Spine cord injury

Astrocytomas (NF1) and ependymomas comprise 90%
of intramedullary tumors and cannot be reliably
differentiated based on imaging features.
*
Hemangioblastomas and intramedullary
metastases are less common.
