To categorize underlying etiologies ofnon-traumatic spinal emergencies To give noteworthy examples and describe the imaging findings throughMR and CT To perform properdifferential diagnosisfor tailored clinical management

Spinal injuries are commonly caused due to trauma. Non-traumatic emergencies are less frequent and consist of a heterogeneous group. Although clinical symptoms are very similar, clinical management is difficult due to a wide variety of etiologies. Non - Traumatic Spinal Emergencies: 1 - Tumors 2 - Infectious / Inflammatory / Autoimmune / Demyelinating 3 - Vascular 4 - Degenerative 5 - Toxic / Metabolic / Paraneoplastic 6 - Iatrogenic

Non - Traumatic Spinal Emergencies: 1 - Tumors Astrocytoma, Ependimoma, Hemangioblastoma, Schwannoma, Menenengioma, Osteosarcoma,Metastasis* (Fig. 1)... *Metastasis: Hematogenous Metastasis: Most commonly due to lung cancer Thoracic > Cervical > Lumbal Drom Metastasis: Most commonly due to medulloblastoma Lumbal > Thoracic Symptoms: Radicular pain, paresthesias, muscle weakness, incontinence... 2 - Infectious / Inflammatory / Autoimmune / Demyelinating Multiple Sclerosis, Neuromyelitis Optica, Neurosarcoidosis, Spondylodiscitis, SLE, Idiopathic transverse myelitis,Behcet's Disease* (Fig. 2)... Behcet's Disease: Mediterranean region (Turkey - highest incidence), middle east Systemic Vasculitis Brain > Spinal Cord...

Non-traumatic spinal emergencies consist of a heterogeneous group and differential diagnosis is varietal. Clinical history recent vaccination, primary tumor, etc. is essential for diagnostic imaging planning and differentials. MRI is the preferred imaging modality whereas radiographs are used for initial evaluation and CT is used as a complementary imaging modality. The collaboration of radiologists and clinicians is indispensable for the clinical management of the patient. The radiologist should be able to define the imaging findings and have a knowledge of a probable differential diagnosis depending...
