Traumatic injuries of the spinal column reflect the mechanisms that produced them. The patterns of these injuries on imaging studies, therefore, help to predict the underlying mechanisms of trauma and lead, in turn, to more complete description of the pathologic…
Key Points Opportunistic central nervous system infections are most commonly seen in patients with human immunodeficiency virus and are usually associated with profound immunosuppression. Hematologic disorders are frequent in cancer patients and may lead to neurological complications caused by thrombocytopenia,…
A broad spectrum of cystic lesions can be identified on spine imaging. Multiple etiologies and different imaging characteristics of these lesions make the differential diagnosis a challenging issue for radiologists. Cysts may develop within the spinal canal and may be…
