Amongst them, together with 14 males and 9 females aged from 28 to 70 years outdated with a median of 53.four years outdated. The medical manifestation primarily deal with ache round spinal and minority peripheral nerve symptom. The programs of illness ranged from 2 weeks to three months with a median of 9 weeks. 9 sufferers underwent CT plain scan, eight sufferers underwent plain and enhanced CT; 21 sufferers underwent MRI plain scan and enhanced; 15 sufferers underwent CT and MRI examination. The situation, bone adjustments, form, density, sign depth and enhancement traits of lesions had been noticed and in contrast with pathology.
RESULTS: Location and dimension of lesion confirmed cervical vertebrae in 1 case, thoracic vertebrae in 16 instances, lumbar vertebrae in 2 instances, and sacral vertebrae in four instances. Mass was bigger, the biggest cross-sectional dimension of group was as much as 73 mm× 125 mm. CT examination confirmed that 11 instances with “cloud and mist” form change, 6 instances with compression fractures, and with “floating ice” form change, 9 instances with “oversleeve” form change, 11 instances with spinal stenosis; enhancement scan confirmed apparent reinforcement. MRI confirmed barely low sign on T1WI and T2WI had been barely excessive sign, and sign was uneven, and enhancement scan confirmed apparent reinforcement, 13 of 16 instances with spinal canal stenosis modified like “oversleeve”, intervertebral area confirmed no vital stenosis. Comparability of CT and MRI confirmed the manifestation of bone destruction by CT was superior than that of MRI, however the vary of lesion, and associated surrounding constructions weren’t higher than MRI. MRI displayed the vary of lesion normally larger than CT. Pathology outcomes confirmed that 23 sufferers had been all main spinal massive B cell lymphoma.
CONCLUSIONS: Main spinal massive B cell lymphoma has sure options in age, location and imaging findings. The “cloud and mist”, “floating ice” and “oversleeve” form bony destruction by CT and MRI has sure significance to analysis of main spinal massive B cell lymphoma.
