Primary B-cell Spinal Cord Lymphoma of the Cervical Spine.

Non-Hodgkin lymphomas are a heterogeneous group of tumours, with diffuse large B-cell lymphomas (DLBCL) being particularly common. Cases of DLBCLs developing in the central nervous system, especially in the spinal cord, are extremely rare and thus pose significant diagnostic and therapeutic problems, particularly for orthopaedists and neurologists since these are the specialists the patients first consult. The tumours often appear in immunosuppressed patients and standard chemotherapy is ineffective. This paper presents the case of a 44-year-old male with a lymphoma located in the spinal cord at the C7-Th1 level. The symptoms appeared suddenly and progressed rapidly, with dissociated sensory loss and limb paresis being the most pronounced. Imaging studies and the rapid symptom progression suggested neoplastic disease. An emergency surgical procedure was performed in order to decompress the spinal cord and thus limit neurological deficits. Tumour resection allowed for making a diagnosis. By four weeks after the surgery, the tumour had grown larger than before the procedure. Chemotherapy with MTX and Ara-C and intrathecal MTX resulted in full remission. Consolidation was achieved with radiotherapy. Currently, with the low incidence of such tumours, there are no standards of management in patients with DLBCLs of the CNS. The literature contains only a few case reports on successfully treated spinal cord DLBCLs.
