A Patient with Splenic Marginal Zone Lymphoma Presenting with Spastic Paraplegia as the Initial Symptom

چکیده
In this report, we describe the case of a patient with splenic marginal zone lymphoma (SMZL) who presented with spastic paraplegia as the initial symptom. A 42-year-old male developed progressive spastic paraplegia over 4 months. His neurologic examination revealed paraplegia with pyramidal syndrome, hypoesthesia below the T1 level, and anal hypotonia. Magnetic resonance imaging (MRI) of the spinal cord revealed an extensive high-intensity signal in T2-weighted sequences and swelling involving the thoracic region and conus medullaris. A laboratory test revealed presence of the serum M component. Abdominal computed tomography images showed moderate splenomegaly. Abnormal lymphocytes of B-cell lineage markers (CD19+, CD20+, and CD25+; surface immunoglobulin κ expression; IgD+ and IgM+) were found in the peripheral blood, cerebrospinal fluid, bone marrow and spleen. Splenectomy confirmed the SMZL diagnosis. After the completion of chemotherapy, the patient was in complete remission, and spinal MRI findings were normal. Intramedullary spinal cord involvement in SMZL is extremely rare, and, to the best of our knowledge, this is the first case of SMZL with intramedullary spinal cord involvement associated with clinical and radiologic signs without the involvement of cerebral structures. Spastic paraplegia can be the initial presentation of SMZL.

We describe a case presenting complaint of complete lower body paraparesis, which was discovered to have splenic marginal zone lymphoma (SMZL). While paraneoplastic syndromes are more common in tumors, such as small cell lung cancer, very few reports exist on this condition with SMZL. We describe such a rare entity with a clinical course spanning twenty-four months after diagnosis.

Relapsing polychondritis (RPC) is a poorly understood phenomenon associated with cartilaginous inflammation of the ear, nose, tracheobronchial tree, and peripheral joints. Many cases of RPC respond to anti-inflammatories and resolve with no further complications. However, RPC has also been linked to more insidious conditions such as malignancies, autoimmune disorders, vasculitis, or underlying ...
