MR Imaging of Spinal Lymphoma

Abstract

Fourteen patients with spinal lymphoma examined by MR imaging were reviewed. Thirteen of them also had extraspinal lymphoma. Vertebral involvement was found in 12 patients, epidural in 10, and paraspinal in 8 patients. On the basis of MR imaging at 0.3 T, spinal lymphoma may be divided into three types of growth pattern according to the main location: paraspinal, vertebral, and epidural. Most frequently, all three locations were found simultaneously on MR (7/14). In one patient the location was vertebral with epidural extension, in one paraspinal with vertebral extension, in 3 it was entirely vertebral, and in 2 entirely epidural. Multiple plane TI-weighted imaging gave complete information about the extent of spinal lymphoma. The signal intensity was lower than or equal to muscle and lower than bone marrow in paraspinal and vertebral lesions on TI-weighted images and high on TZweighted images. Epidural lesions showed a hypo-or isointense signal relative to the cord on TI-weighted images except in one case and a hyperintense signal on T2-weighted images. Compression of the cord and cauda equina due to bulging of diseased vertebral bodies and epidural lesions was well demonstrated. MR imaging was also found useful in the follow-up of treatment.

Primary spinal epidural non-Hodgkin’s lymphoma presented with spinal cord compression syndrome

“…The lesion was enhanced on the administration of contrast agent. These observations suggest that PSENLs has characteristic appearances on MRI, as noted in other reports [18][19][20][21][22]. Although the MRI appearance of this tumor was quite typical, it should be differentiated from spinal epidural hematoma, abscess, and metastatic carcinoma.…”

Primary spinal epidural lymphomas

“…There does not appear to be a change with differing grades of lymphomas. [133031] Contrast enhancement helps us in better delineating the pathology (i.e., carcinoma, myeloma, and sarcoma). T2-weighted imaging often shows a higher signal than fat.…”

Primary Spinal Epidural Lymphoma: Case Report

“…kalizasyonuna göre üç tipe ayrılır: Paraspinal, vertebral ve epidural. 5 NHL'nin ekstranodal tutulumu, nodal tutuluma göre daha az görülür. Ekstranodal lenfomanın epidural mesafeyi etkilemesi son derece nadir görülen bir olaydır, SENHL tüm lenfomaların yaklaşık % 4'ünü oluşturur.…”

“…Hastalığın evrelenmesinde faydalı olan kemik iliği infiltrasyonunu gös-termede yardımcıdır. 5,9 Sürekli sırt ağrısı ve alt ekstremitede duyu kaybı varsa zaman kaybetmeden MRG yapılmalıdır. Spinal epidural kitlelerde erken tanı ve tedavi ile parapleji ve sfinkter disfonksiyonu gibi komplikasyonlar önlenebilir.…”
