Spine MR imaging features of subacute combined degeneration patients

Abstract

Symmetric T2-hyperintensity within dorsal column of spinal cord is commonly seen in SCD patients with a linear pattern in the cervical spine and a nodular pattern in the thoracic spine.

Subacute combined degeneration of the cervical and dorsal spinal cord in a 40-year-old male patient: A case report

“…On the axial planes, the bilateral high-intensity T2 signals within the posterior funiculus of the cervical spinal cord resemble the appearance of an inverted letter “V,” thus called the inverted V-sign [10 , [12] , [13] , [14] . One case series mentioned high-intensity T2 signal resembling a “dumbbell” or “binoculars” on the axial planes of the thoracic spinal cord [15] . Contrast enhancement of the spinal cord has been sporadically described [10 , 16] .…”

Degeneración subaguda combinada secundaria a infección crónica por Helicobacter pylori. Reporte de caso

“…En un artículo publicado recientemente por Sun y cols. [16] se evaluaron 8 pacientes con degeneración subaguda combinada. De ellos, 7 presentaron hiperintensidad del aspecto posterior del cordón espinal; 5 lo presentaron en la médula cervical, y 2, en la médula torácica.…”

The Role of Vitamin B12 in the Management and Optimization of Treatment in Patients With Degenerative Cervical Myelopathy

“…Two studies have shown that elevated levels of Hcy and MMA were detectable in 15% to 33% of patients with normal Schilling tests, indicating the increased specificity of laboratory measurements in diagnosing B 12 deficiency. 29,30 Magnetic resonance imaging (MRI) is not normally indicated for patients with B 12 deficiency, but some reports have noted characteristic V-shaped hyperintensity on T2-imaging when present in the cervical cord and "bumbell" or bilateral nodular shape when present in the thoracic cord in patients with severe myelopathy 31,32 (Figure 2).…”
