We report a 54-year-old man with vitamin B12 deficiency myelopathy limited to the upper extremity region. He was well until October, 1995, when he had an onset of exertional dyspnea and general fatigue. Then he noted tingling sensation in bilateral upper extremities in March, 1996. He had undergone total gastrectomy due to gastric ulcer 15 years ago. Neurological examination revealed superficial and vibratory sensory loss in the upper extremities distal to elbows, and pseudoathetoid movement of the left fingers. Otherwise neurological examination was unremarkable. Laboratory examination revealed macrocytic anemia, and low serum vitamin B12. However, serum folate was within the normal range. In SEP studies, median nerve stimulation evoked peripheral N9 and N13 potentials, but not cortical N20 one. Posterior tibial nerve stimulation elicited normal responses. MEP, VEP, needle EMG, and nerve conduction studies gave normal findings. T2-weighted MRI showed high signal intensity lesions at the C1-Th1 level in the posterior column, especially in the cuneate fascicles. The gracile fascicles were spared. This is a very rare case of myelopathy due to vitamin B12 deficiency presenting only sensory disturbances in both upper extremities. The lesions limited in the cuneate fascicle were confirmed by electrophysiological, and neuroradiological examinations.

A 71-year-old man was admitted to our hospital because of systemic edema and exertional dyspnea. Chest radiographs revealed infiltrative shadows in both lung fields, pleural effusion, and pericardial effusion. Seven years before, he had undergone gastric surgery for a gastric ulcer with lymphoid hyperplasia. In the pathologic diagnosis based on the percutaneous lung biopsy, hyalinizing granuloma was suspected. For a more thorough diagnosis, the patient was subjected to an open lung biopsy, and the final diagnosis was low-grade B-cell lymphoma of the MALT (mucosa-associated lymphoid tissue) type. Gallium scintigraphy showed accentuated accumulation in the left neck and hypothyroidism was present. Histologic re-examination of the resected stomach revealed infiltration of centrocyte-like cells and lymphoepithelial lesions, compatible with the pathologic features of MALT lymphoma. We considered that the gastric neoplasm and the pulmonary, pleural, and thyroid tumors of MALT lymphoma had occurred seven years apart in this case. Thyroid hormone replacement and CHOP therapy improved the symptoms and decreased the lung tumor size by 73%. MALT lymphomas tend to remain localized for a long period. The multiorgan involvement seen in this case is rather rare.
