A 62-year-old woman was admitted with general malaise and anorexia in September, 1988. Multiple myeloma (IgA-lambda, Stage IIIb) was diagnosed, and amyloidosis was also diagnosed by abdominal fat aspiration biopsy. A partial remission was achieved by MEVP combination chemotherapy, and she was discharged in December, 1988. She was readmitted because of dizziness and palpitation in April, 1989. A diagnosis of sick sinus syndrome was made, and a VVI permanent pacemaker (PPM) was implanted. She was able to walk to our outpatient clinic for 10 months after the PPM implantation. However, right hemiplegia and aphasia were recognized on April 19, 1990. CT scans revealed low density in the areas of the left anterior and middle cerebral artery. The symptoms of congestive heart failure worsened progressively, and the patient, who had been confined to bed, died on March 5, 1991. She was the fifth myeloma-associated amyloidosis patient who received a PPM implantation. Her survival time was one year and ten months, and was the longest among a small number of reported cases with PPM implantation.

Multiple myeloma rarely presents with neurological symptoms. We describe two patients with pseudo-stroke manifestation of multiple myeloma. The first patient was a 60-year-old female with the initial presentation of multiple myeloma forming a large skull tumour compressing the brain with resultant symptoms of aphasia, limited logical contact and right upper extremity paresis. The second patient was a 69-year-old female who presented with a partial motor epileptic seizure involving both right limbs with persisting weakness of muscles and speech disturbances due to a skull tumour 4 years after the diagnosis of multiple myeloma. Pseudo-stroke manifestation of multiple myeloma is extremely uncommon, however it can sometimes be observed both as an initial presentation and in the course of long-lasting disease.

Immunomodulatory drugs (IMiDs) currently used in the treatment of multiple myeloma, are thalidomide, lenalidomide and pomalidomide. One of the most common side effects of thalidomide is neurotoxicity, predominantly in the form of peripheral neuropathy. We report 6 cases of significant central neurotoxicity associated with IMiD therapy. Treatment with thalidomide (1 patient), lenalidomide (4 patients), and pomalidomide (1 patient) was associated with various clinical manifestations of central neurotoxicity, including reversible coma, amnesia, expressive aphasia, and dysarthria. Central neurotoxicity should be recognized as an important side effect of IMiD therapy.

Chimeric antigen receptor T cell therapy has become an important tool in the treatment of relapsed and refractory malignancy; however, it is associated with significant neurological toxicity. We characterized the neurological toxicity associated with chimeric antigen receptor T-cell therapy in a consecutive series of 100 patients up to 2 months post transfusion, 28 of whom were obtained from chart review and the others by prospective observation. The underlying neoplasms were lymphoma (74%), myeloma (14%), leukaemia (10%), and sarcoma (2%). The median age of the cohort was 64.5 years old and 39% of patients were female. The most commonly occurring neurological symptoms were encephalopathy (57%), headache (42%), tremor (38%), aphasia (35%) and focal weakness (11%). Focal neurological deficits are frequently observed after chimeric antigen receptor T-cell therapy and are associated with regional EEG abnormalities, FDG-PET hypometabolism, and elevated velocities on transcranial Doppler ultrasound. In contrast, structural imaging was typically normal. As this form of treatment is more widely adopted, recognition of the frequently encountered symptoms will be of increasing importance for the neurologists and oncologists caring for this growing patient population.
